Is There A Minimum Age for the Shingles Vaccine? – Healthline

September 18, 2022

If youre like an estimated 99% of people born before 1980, chances are youve had the varicella-zoster virus, which causes chickenpox. It usually shows up in childhood with a trademark itchy and crusty rash, though it can strike at any time, with or without symptoms.

Many people who got chickenpox as a child have long since forgotten about it or perhaps never knew they had it in the first place. But fast forward a few decades and you may experience a potentially painful and long lasting complication: herpes zoster, also called shingles.

There is a shingles vaccine. The Food and Drug Administration (FDA) approved Shingrix in 2017 after finding it safe and highly effective at preventing shingles. But its mostly recommended for people ages 50 and over.

Read on to learn about the reasons behind the over-age-50 rule and a few exceptions to that rule.

The Centers for Disease Control and Prevention (CDC) recommends the shingles vaccine for people with healthy immune systems who are ages 50 and over. This is because your immune system becomes less robust as you age, so your risk of developing shingles increases.

The CDC also recommends the vaccine for people ages 19 and over who are immunocompromised. This means they have a weakened immune system.

Shingrix is a vaccine that contains an inactive form of the herpes zoster virus. It helps you develop an immunity to the active virus.

Adults receive the vaccine in two separate doses. Generally, healthy adults over age 50 get their second dose 2 to 6 months after the first dose. Immunocompromised adults may get the second dose sooner.

There is no maximum age for getting Shingrix.

Shingles is caused by a reactivation of the varicella-zoster virus, which is the virus that causes chickenpox.

When you get chickenpox and recover, the varicella-zoster virus doesnt go away. Instead, it stays dormant in your nerve cells. As you get older, your body is less able to fight off viruses. During this time, the virus can reactivate.

The hallmark sign of shingles is a pronounced rash of painful blisters filled with clear fluid. It usually shows up on one side of the body, especially on the head, neck, or torso. That said, it can appear anywhere on your body.

Other symptoms include:

The blisters typically start healing within 7 to 10 days and go away within a month. Yet the condition can sometimes cause persistent nerve pain, called postherpetic neuralgia (PHN).

PHN may affect the same area where you had the shingles rash. It can persist for months or years, become intensely painful, and sometimes interfere with daily life.

About 1 million people get shingles each year. The risk of getting shingles gets higher as you get older. In fact, people ages 65 or over are three times more likely to get shingles than younger people.

According to the CDC, 1 in 3 people will get shingles in their lifetime. Shingles is more common in women than in men, and it is more common in white people than in Black people.

Risk factors for shingles include:

Certain conditions or medications that affect your bodys immunity also increases your risk, particularly:

People born after 1995 are less likely to get shingles because they are less likely overall to get chickenpox. That year, a vaccine was released, which reduced chickenpox transmission significantly.

You can get shingles after vaccination with the chickenpox vaccine, but its less likely than if you got chickenpox.

Depending on when you get Shingrix, the vaccine is more than 90% effective in preventing shingles and PHN.

Chickenpox and shingles are caused by the same virus, varicella-zoster. When you recover from chickenpox, the virus stays in the cells in your nervous system.

It can become active again if your body is no longer able to suppress it. It spreads down nerve fibers and up to your skin, causing a rash, inflammation, burning, and pain.

A doctor will examine the rash on your skin and ask you about your symptoms. This is usually how healthcare professionals diagnose shingles.

A healthcare professional may remove some fluid from a blister for testing, but typically this is not necessary.

Vaccination is the key to preventing shingles. The CDC recommends:

According to the CDC, you should get the vaccine even if, in the past, you:

Creating and maintaining healthy lifestyle habits such as stress management, a healthy diet, regular exercise, and getting plenty of sleep can also help prevent or lessen flare-ups.

Shingles can be painful but the blisters often begin to heal within a week. Your skin usually clears up within a month.

People who develop PHN can have it for months or years afterward, but not everyone who has shingles will develop PHN.

Healthcare professionals can help treat shingles and shorten its duration with prescription antiviral drugs. These can also reduce your likelihood of having PHN.

Most people only get shingles once, though it is possible to get it again.

Shingrix is not recommended for adults under age 50 who have a healthy immune system.

It is recommended for adults ages 19 or over who are immunocompromised, such as people with an immune-related health condition or who are receiving immunosuppressive agents, which are medications that reduce the bodys immune response. These medications may help prevent organ rejection after an organ transplant and treat other medical conditions.

Its recommended that you get a second dose between 2 and 6 months after the first. But, if you have waited longer than 6 months, according to the CDC, you will not have to start over. Just get your second dose as soon as possible.

Yes. You can still catch the varicella-zoster virus if youve never had chickenpox, and that may cause shingles.

Immunity stays strong for at least 7 years and is more than 90% effective at preventing shingles and PHN among people ages 50 and over, per the CDC. It is between 68% to 91% effective in immunocompromised adults over age 18.

Most people dont develop side effects from the shingles vaccine, but some can occur. The vaccine is injected into your arm, so pain and soreness at the injection site are common.

The FDA also issued a warning in 2021 that there may an association between receiving the vaccine and developing Guillain-Barr Syndrome (GBS), though the relationship is poorly understood and more research is needed.

GBS is a rare condition in which your bodys immune system attacks part of the nervous system.

No, the CDC recommends that all people over age 50 get the shingles vaccine.

You should not get Shingrix if you:

Shingles is a painful condition caused by the same virus as chickenpox. The virus can remain dormant in your nervous system for decades before reactivating.

There is one FDA-approved vaccine that prevents shingles and its complications. Its usually given to adults over age 50 or to those ages 19 or over who have compromised immune systems. Your doctor may be able to prescribe it to you sooner depending on your circumstances.

If you do get shingles, it usually goes away within a month. Yet its possible to develop PHN that lasts for months or years. Your healthcare professional may be able to prescribe antiviral drugs that will shorten the duration of the shingles infection and help prevent PHN.

Nearly 50 Members of Congress Call on Pentagon to End Military Vaccine Mandate – The Epoch Times

September 18, 2022

Nearly 50 Republican lawmakers, led by Rep. Mike Johnson (R-La.), have called on theDepartment of Defense (DOD) to withdraw its COVID-19 vaccine mandate for military members, citing concerns over the mandates impact onthe readiness of the U.S. Armed Forces.

In a letter toSecretary of Defense Lloyd Austin dated Sept. 15 (pdf), lawmakers, includingReps. Chip Roy (R-Texas) and Thomas Massie(R-Ky.), expressed their grave concerns over the impact of the mandate, particularly with regard to theU.S. Army.

As a result of your mandate, eight percent of the Armys approximately 1 million soldiers face expulsion, Army recruiters cannot meet their FY22 target, and the Army has cut its projected FY23 end strength by 12,000 soldiers, they wrote.

Referring to Russias ongoing invasion of Ukraine, lawmakers noted that the U.S. military currently facesa self-imposed readiness crisis.

Citing sparse data from the Department of Army, they noted that at least 40,000 National Guardsmen, 20,000 Army Reservists, and at least 15,000 Active Army Soldiers have not yet received a COVID-19 shot and subsequently face being discharged from service.

The Department of Defenses own Covid response page indicates that approximately 900,000 soldiers are fully vaccinated out of the 1 million soldiers in the Army, Army Reserve, and Army National Guard, they wrote.

Lawmakers pointed totestimony delivered in July byVice Chief of Staff of the Army, Gen. Joseph Martin, before theHouse Armed Services Committee. During that testimony,Martin stated that less than 20,000 people werefacing discharge for refusing to take the COVID-19 vaccine, much less than the initial figures that officials had provided.

However, lawmakers in their letter to the DODnoted that the Army has not published official data pertaining to the number of unvaccinated service members in months.

The opaqueness of the Department continues to frustrate Members of Congress attempting to perform oversight of the Executive Branch, they wrote, noting that their repeated inquiries remain unanswered.

Republicans also pointed to the thousands of servicemembers that have been left in limbo while they await a formal judgment regarding their medicalexemptions to the vaccine.

Some have waited for nearly a year to learn if they will be forcibly discharged for their sincerely held religious beliefs or medical concerns, lawmakers wrote.

Furthermore, according to current Army policy, even those few soldiers who receive permanent exemptions will be treated as second-class soldiers for the rest of their careerseach of them requires approval from the Undersecretary of the Army to travel, change assignments, or even attend training courses away from their home station, they wrote.

According to U.S Army fragmentary orderspublishedby Fox News, the Army has barred unvaccinated soldiers from official travel unless they receive the undersecretarys approval.

The Department has abused the trust and good faith of loyal servicemembers by handling vaccine exemptions in a sluggish and disingenuous manner, lawmakers said.

They then questioned who would replace the roughly 75,000 soldiers if they were to be discharged from the Army. Martin said in July that if a shortfall in Army troop size were to persist, it could have an impact on readiness.

Citing Army Secretary Christine Wormuths interview with NBC News earlier this year in which she noted that the Army has only met 52 percent of its recruiting goal for the fiscal year 2022, they asked, How will it recruit another 75,000 troops beyond its annual target to account for vaccine-related discharges?

In that same interview,Wormuth said she believes the Army would end up roughly12,000 to 15,000 recruits short this year.

The data is now clear. The Department of Defenses Covid vaccine mandate is deleterious to readiness and the militarys ability to fight and win wars, lawmakers concluded. The vaccine provides negligible benefit to the young, fit members of our Armed Forces, and the mandates imposition is clearly affecting the Departments ability to sustain combat formations and recruit future talent.

We urge you to immediately revoke your Covid-19 vaccine mandate for all servicemembers, civilian personnel, and contractors and re-instate those who have already been discharged.

As of July 1, 2022, under the Biden administrations vaccine mandate,members of the Army National Guard and U.S. Army Reserve who are not vaccinated and do not have an approved exemption are unable toparticipate in federally funded drills and training and will not receive pay or retirement credit.

BidensCOVID-19 vaccine mandate has been in place across the entire military since last year and the White House has defended the move, stating that mass vaccination will help stem the spread of the virus.

The Epoch Times has contacted the Department of Defense for comment.

New Omicron-fighting Covid vaccine supplied with flimsy needles across Scotland to get replacement syringes – STV News

September 18, 2022

Vaccination centres across Scotland are to receive replacement syringes after warnings needles supplied with a new Omicron targeting Covid vaccine were unfit for purpose.

NHS staff complained about the dose administering devices that came with the Moderna Spikevax Bivalent jab that is the first that has been approved to target two strains of the virus.

Vaccinators said the needles bend when they try to pierce vials of the vaccine.

It comes as Scottish Covid rates increase for second week in a row.

National Services Scotland, the body that provides supplies and advice to the NHS across the country, said alternative products would be sought to avoid any disruption to the vaccination programme that has already begun its autumn rollout.

Following complaints, the UK Health Security Agency (UKHSA) which has procured the Moderna jab across the four-nations, said it would supply a different needle and syringe as a precautionary measure.

At this time we are not issuing a product recall, but this decision will allow us time to fully investigate the issues raised, said Gareth Thomas, deputy director of vaccines and countermeasures at UKHSA.

National Services Scotlands director of national procurement said that the new needles would be sent out across Scotland while the feedback received is investigated.

Gordon Beattie said: We can confirm that UKHSA have communicated to us today that as a precautionary measure, they are arranging for alternative combined needles and syringes to be supplied in Scotland whilst they investigate the feedback received about the combined needles and syringes that were recently brought into use.

The alternative product is virtually identical to the one successfully used as part of the Covid programme with the Pfizer vaccine, UKHSA said.

We are aware that some NHSE sites are experiencing some problems with the use of the new needle and syringe being supplied for administrating the Moderna bivalent vaccine, the UKHSAs Mr Thomas said.

The Medicines and Healthcare products Regulatory Agency (MHRA) authorised Modernas bivalent vaccine, which targets both the original Covid strain and the Omicron variant, on August 15.

Known as mRNA-1273.214, the dose is an updated version of the Moderna vaccine which is already in use for first, second and booster doses.

The Office for National Statistics (ONS) Coronavirus Infection Survey found around one in 45 people in Scotland had the virus in the week to September 5, up from one in 50 the week before.

The most recent figure equates to around 2.16% of the population, or an estimated 113,500 people.

According to the ONS, Scotland has the highest rates of Covid-19 of any country in the UK, with Northern Ireland showing around one in 55 people are infected, England one in 85 and Wales one in 110.

The autumn flu and Covid vaccination programme is under way for thousands of people across Scotland.

Health Boards are prioritising care homes at the beginning of the roll out; with residents and staff first to receive their jabs.

Health and social care workers and carers will be invited to book their combined flu/Covid-19 appointment using the online portal, with a range of sites/times available to choose from.

How others receive their jab will depend on a number of factors. Full details are available on the Scottish Government website.

Astrocytes, the Covid vaccine and the 2021 classification – Brain Tumour Research

September 18, 2022

Researchers at Tel Aviv University have reported that they effectively eradicated glioblastoma using a method based on their discovery of two critical mechanisms in the brain that support tumour growth and survival: one protects cancer cells from the immune system, while the other supplies the energy required for rapid tumour growth. The work found that both mechanisms are controlled by brain cells called astrocytes, and in their absence, the tumour cells die and are eliminated.

A paper detailing this work was published in the scientific journal Brain

Researchers at University College London (UCL) and Great Ormond Street Hospital (GOSH) have been awarded a 1.2 million grant from Great Ormond Street Hospital Childrens Charity (GOSH Charity) to develop a new treatment for an aggressive type of brain tumour, diffuse midline glioma (DMG), until recently known as diffuse intrinsic pontine glioma (DIPG). They will be using a patients own immune system to attack the cancer cells.

The team will use CAR T-cells (patient immune cells engineered to recognise and eradicate cancer cells) in a clinical study for up to 12 patients with DMG at GOSH.

With results from a study at Stanford University in the USA already showing promise of CAR T-cell therapy in DMG, it is hoped that this clinical trial at GOSH will be a crucial first step in developing effective CAR T-cell treatments for DMG and other high-risk brain tumours that can be devastating to families.

A New Human Fetal Brain Atlas Decodes the Origin and Formation of Brain Cancer. Medulloblastomas are classified into four major subgroups. Three main groups originate from the cerebellum, and one is from the dorsal brainstems lower rhombic lip. In this research, rodent models have been used to help understand the origins of cerebellar tumorigenesis. An analysis of their molecular, cellular, and histological models has aided research in studying brain tumours and this could help scientists plan for better outcomes.

Recent research has uncovered a unique metabolic vulnerability in the sphingolipid pathways of gliomas that possess the IDH1 mutation. Sphingolipids are a family of lipid signalling molecules that play a variety of second messenger functions in cellular regulation. The two primary metabolites, sphingosine-1-phosphate (S1P) and ceramide, maintain a rheostat balance and play opposing roles in cell survival and proliferation. Altering the rheostat such that the pro-apoptotic signalling of the ceramides outweighs the pro-survival S1P signalling in glioma cells diminishes the hallmarks of cancer and enhances tumour cell death. This review discusses the sphingolipid pathway to identify the enzymes that can be most effectively targeted to alter the sphingolipid rheostat and enhance apoptosis in gliomas.

The World Health Organization (WHO) has published the fifth edition of the Classification of Tumors of the Central Nervous System (CNS). This 2021 update introduces major improvements that will have an important influence on clinical care and research of brain tumours, especially diffuse gliomas. It will provide clinicians with more accurate guidance on prognosis and optimal therapy for patients and ensure that more homogenous patient populations are enrolled in clinical trials, potentially facilitating the development of more effective therapies.

This is paid for content and offers a review of the mechanisms of T cellmicroglia interactions and discusses a collaboration fostering heterogeneity and immunosuppression in brain cancers.

Surveys:

A new comprehensive statistical report on childhood and adolescent brain tumours ages 0-19 years has been published. The Central Brain Tumor Registry of the United States (CBTRUS) Statistical Report: Paediatric Brain Tumour Foundation Childhood and Adolescent Primary Brain and Other Central Nervous System Tumors Diagnosed in the United States in 20142018 comprehensively describes the current population-based incidence of primary malignant and non-malignant brain and other CNS tumours in children and adolescents ages 019 years, collected and reported by central cancer registries covering approximately 100% of the United States population.

Brain tumour patients and COVID-19 vaccines: results of an international survey. A total of 965 unique surveys were completed from 42 countries of an anonymous 31-question online survey conducted in the summer of 2021. The survey was open to adult brain tumour patients over the age of 18. The purpose of this study was to determine if brain tumour patients and their caregivers have received a COVID-19 vaccine and explore their thoughts and opinions on these vaccines.

Opportunities:

There is an opportunity to join Professor Oliver Hanemann at our University of Plymouth research Centre as a research focused lecturer meanwhile Kings College London are looking for an enthusiastic Postdoctoral Research Associate to lead a project on ultrasound-mediated paediatric brain tumour treatment using drug-loaded thermosensitive liposomes.

New Believe Magazine out now if the clinicians amongst you would like to have the opportunity to have the Believe Magazine (full of fundraising/campaigning/research news) available to view in public spaces at your clinics please let me know and we will send a box over to you.

Finally this week why not make the most of the Autumn weather and join us for our national Walk of Hope which is taking place on Saturday 24thSeptember. This year, we want to make it our biggest Walk of Hope yet and we need your help.

The Unintended Consequences of COVID-19 Vaccine Policy The Wire Science – The Wire Science

September 10, 2022

Since 2021, mandatory proof-of-vaccination policies have been implemented and justified by governments and the scientific community to control COVID-19. These policies, initiated across the political spectrum, including in most liberal democracies, have spread globally and have involved:

(See table.)

The publicly communicated rationale for implementing such policies has shifted over time. Early messaging around COVID-19 vaccination as a public health response measure focused on protecting the most vulnerable. This quickly shifted to vaccination thresholds to reach herd immunity and end the pandemic and get back to normal once sufficient vaccine supply was available.1 2 In late summer of 2021, this pivoted again to a universal vaccination recommendation to reduce hospital/intensive care unit (ICU) burden in Europe and North America, to address the pandemic of the unvaccinated.

COVID-19 vaccines have represented a critical intervention during the pandemic given consistent data of vaccine effectiveness averting COVID-19-related morbidity and mortality.36 However, the scientific rationale for blanket mandatory vaccine policies has been increasingly challenged due to waning sterilising immunity and emerging variants of concern.7 A growing body of evidence shows significant waning effectiveness against infection (and transmission) at 1216 weeks, with both delta and omicron variants,813 including with third-dose shots.14 15

Since early reports of post-vaccination transmission in mid-2021, it has become clear that vaccinated and unvaccinated individuals, once infected, transmit to others at similar rates.16 Vaccine effectiveness may also be lower in younger age groups.17 While higher rates of hospitalisation and COVID-19-associated morbidity and mortality can indeed be observed among the unvaccinated across all age groups,36 broad-stroke passport and mandate policies do not seem to recognise the extreme risk differential across populations (benefits are greatest in older adults), are often justified on the basis of reducing transmission and, in many countries, ignore the protective role of prior infection.18 19

Mandate and passport policies have provoked community and political resistance including energetic mass street protests.20 21 Much of the media and civil debates in liberal democracies have framed this as a consequence of anti-science and right-wing forces, repeating simplistic narratives about complex public perceptions and responses. While vaccine mandates for other diseases exist in some settings (e.g., schools, travel (e.g., yellow fever) and, in some instances, for healthcare workers (HCWs)),22 population-wide adult mandates, passports, and segregated restrictions are unprecedented and have never before been implemented on this scale.

These vaccine policies have largely been framed as offering benefits (freedoms) for those with a full COVID-19 vaccination series,23 24 but a sizeable proportion of people view conditioning access to health, work, travel and social activities on COVID-19 vaccination status as inherently punitive, discriminatory and coercive.20 21 2528 There are also worrying signs that current vaccine policies, rather than being science-based, are being driven by sociopolitical attitudes that reinforce segregation, stigmatisation and polarisation, further eroding the social contract in many countries.

Evaluating the potential societal harms of COVID-19 pandemic restrictions is essential to ensuring that public health and pandemic policy is effective, proportionate, equitable and legally justified.29 30 The complexity of public responses to these new vaccine policies, implemented within the unique sociopolitical context of the pandemic, demands assessment.

In this paper, we reflect on current COVID-19 vaccine policies and outline a comprehensive set of hypotheses for why they may have far-reaching unintended consequences that prove to be both counterproductive and damaging to public health, especially within some sociodemographic groups. Our framework considers four domains: (1) behavioural psychology, (2) politics and law, (3) socioeconomics, and (4) the integrity of science and public health (see figure 1).

Our aim is not to provide a comprehensive overview or to fully recapitulate the broad ethical and legal arguments against (or for) COVID-19 vaccine mandates and passports. These have been comprehensively discussed by others.3133 A full review of the contribution of mandates and passports to COVID-19 morbidity and mortality reductions is not yet possible, although some existing studies on vaccine uptake are cited below.

Rather, our aim is to add to these existing arguments by outlining an interdisciplinary social science framework for how researchers, policymakers, civil society groups and public health authorities can approach the issue of unintended social harm from these policies, including on public trust, vaccine confidence, political polarisation, human rights, inequities and social well-being. We believe this perspective is urgently needed to inform current and future pandemic policies. Mandatory population-wide vaccine policies have become a normative part of pandemic governance and biosecurity response in many countries.

We question whether this has come at the expense of local community and risk group adaptations based on deliberative democratic engagement and non-discriminatory, trust-based public health approaches.

What can we learn from the behavioural sciences?

Reactance, entrenchment and vaccine uptake

Apart from mandatory vaccination of the elderly (planned in Czech Republic, Greece, Malaysia and Russia), most policies do not specify individuals at higher risk of severe COVID-19 outcomes among whom COVID-19 vaccine uptake rates, and vaccine confidence, are very high.34 35

Although studies suggest that current policies are likely to increase population-level vaccination rates to some degree,3639 gains were largest in those under 30 years old (a very low-risk group) and in countries with below average uptake.36 Moreover, insights from behavioural psychology suggest that these policies are likely to entrench distrust and provoke reactance a motivation to counter an unreasonable threat to ones freedom.

Literature reviewed by Drury et al,40 including a survey by Porat et al41 in the UK and Israel, found that compulsory COVID-19 vaccination would likely increase levels of anger, especially in those who are already mistrustful of authorities, and do little to persuade the already reluctant. Two experiments in Germany and the USA found that a new COVID-19 vaccine mandate would likely energise anti-vaccination activism, reduce compliance with other public health measures, and decrease acceptance to future voluntary influenza or varicella (chickenpox) vaccines.42 43

A third experiment found that selective mandates increased reactance when herd immunity targets were not clearly explained44 which most governments failed to communicate adequately and convincingly as they shifted their rationale from herd immunity to hospital/ICU admission metrics. De Figueiredo et al45 found that vaccine passports in the UK would induce a net decrease in inclination to get vaccinated among those who had not received a full vaccination dose, while Bell et al46 found that UK HCWs who felt pressured to get vaccinated were more likely to have declined the COVID-19 vaccine.

Jrgensen et al47 found that the reintroduction of vaccine passports in late 2021 in Denmark increased distrust among the unvaccinated. Finally, recent evidence from France suggests that the passe sanitaire was associated with increased vaccination but that it did so to a lower extent among the most vulnerable, may have contributed to increased nocebo effects and did not reduce vaccine hesitancy itself; the authors concluded: Mandatory vaccination for COVID-19 runs the risk of politicising vaccination further and reinforcing distrust of vaccines.48

Cognitive dissonance

The public interpretation of these policies has occurred within the context of the rapidly changing pandemic. Oftentimes, public announcements and media coverage have oversimplified, struggled to communicate potential adverse events (including a potentially higher risk in the convalescent)49 and overstated vaccine efficacy on transmission. Significant public concerns about safety signals and pharmacovigilance have been furthered by the lack of full transparency in COVID-19 clinical trial data50 51 as well as shifting data on adverse effects, such as blood-clotting events,52 myocarditis53 and altered menstrual periods.54

These changes have been associated with changes to vaccination guidelines in terms of eligibility for different vaccines in some countries. Mandates, passports and segregated restrictions create an environment where reactance effects are enhanced because people with low vaccine confidence see contradictory information as validating their suspicions and concerns. The pressure to vaccinate and the consequences of refusal heighten peoples scrutiny of information and demand for clarity and transparency. Current policies have likely facilitated various layers of cognitive dissonance a psychological stress precipitated by the perception of contradictory information.

Citing the potential for backlash and resistance, in December 2020, the director of the WHOs immunisation department stated: I dont think we envision any countries creating a mandate for [COVID-19] vaccination.55 Many governments originally followed with similar public statements, only to shift positions, often suddenly, in mid- or late-2021 during the delta or omicron surge, including in Austria (the first country to announce a full population-wide mandate).56 57

Cognitive dissonance may have been compounded by the changing rationale provided for vaccine mandate policies, which originally focused on achieving herd immunity to stop viral transmission and included public messaging that vaccinated people could not get or spread COVID-19. Policies often lacked clear communication, justification and transparency, contributing to persistent ambiguities and public concerns about their rationale and proportionality.58 In late 2021, however, the re-introduction of onerous non-pharmaceutical interventions in countries with mandates and passports perpetuated cognitive dissonance, since governments had made promises that vaccination would ensure a return to normal and many people (especially younger people) had vaccinated based on these announcements.36 48

When mandate rules are perceived to lack a strong scientific basis, the likelihood for public scrutiny and long-term damage to trust in scientific institutions and regulatory bodies is much higher. A good example is the lack of recognition of infection-derived immunity in employer-based vaccine mandates and passports in North America, including most universities and colleges.59 Despite clear evidence that infection-derived immunity provides significant protection from severe disease on par with vaccination,18 31 prior infection status has consistently been underplayed.

Many individuals with post-infection immunity have been suspended or fired from their jobs (or pushed to leave) or been unable to travel or participate in society31 5659 while transmission continued among vaccinated individuals in the workplace. This inconsistency was widely covered in American conservative and libertarian-leaning media in ways that reinforced distrust not only about the scientific basis of vaccine policies but also the entire public health establishment, including the US Centers for Disease Control and Prevention (CDC).

Stigma as a public health strategy

Since 2021, public and political discourse has normalised stigma against people who remain unvaccinated, often woven into the tone and framing of media articles.60 Political leaders singled out the unvaccinated, blaming them for: the continuation of the pandemic; stress on hospital capacity; the emergence of new variants; driving transmission to vaccinated individuals; and the necessity of ongoing lockdowns, masks, school closures and other restrictive measures (see table 2).

Political rhetoric descended into moralising, scapegoating, and blaming using pejorative terms and actively promoting stigma and discrimination as tools to increase vaccination. This became socially acceptable among pro-vaccine groups, the media and the public at large, who viewed full vaccination as a moral obligation and part of the social contract.61 The effect, however, has been to further polarise society physically and psychologically with limited discussion of specific strategies to increase uptake especially in communities where there would be disproportionately larger individual and societal benefits.

There is rarely a discussion of who and why people remain unvaccinated. Vaccine policy appears to have driven social attitudes towards an us/them dynamic rather than adaptive strategies for different communities and risk groups.

Leveraging stigma as a public health strategy, regardless of whether or not individuals are opposed to vaccines, is likely to be ineffective at promoting vaccine uptake.62 Unvaccinated or partially vaccinated individuals often have concerns that are based in some form of evidence (e.g., prior COVID-19 infection, data on age-based risk, historical/current trust issues with public health and governments, including structural racism), personal experiences (e.g., direct or indirect experience of adverse drug reactions or iatrogenic injuries, unrelated trauma, issues with access to care to address adverse events, etc) and concerns about the democratic process (e.g., belief that governments have abused their power by invoking a constant state of emergency, eschewing public consultation and over-relying on pharmaceutical company-produced data) that may prevent or delay vaccination.45 46 6366

Inflammatory rhetoric runs against the pre-pandemic societal consensus that health behaviours (including those linked to known risk factors for severe COVID-19, for example, smoking and obesity) do not impact the way medical, cultural or legal institutions treat individuals seeking care. Some governments discussed or imposed medical insurance fines or premiums on the unvaccinated, while hospital administrators considered using vaccination status as a triage protocol criterion. The American Medical Association released a statement decrying the refusal to treat unvaccinated patients67 but this has not prevented the ongoing narrative of shaming and scapegoating people choosing not to get vaccinated.

Trust, power and conspiracy theories

Trust is one of the most important predictors of vaccine acceptance globally68 69 including confidence in COVID-19 vaccines.63 70 71 Data show that being transparent about negative vaccine information increases trust and Petersen et al72 found that when health authorities are not transparent, it can increase receptivity to alternate explanations.

COVID-19 vaccine policies have the potential to erode vaccine confidence, trust and the social contract in the particular context of the pandemic, which has exacerbated social anxieties, frustrations, anger and uncertainty. By the time COVID-19 vaccine mandates were introduced, many communities had struggled under lockdowns and other severe public health restrictions, undergone a succession of pandemic waves with changing rules that stretched public confidence in government, had their economic security and livelihoods negatively impacted and been exposed to a media-induced culture of fear perpetuated by an abundance of conflicting and confusing information. All of this occurred within the broader global trend of increasing inequities between North and South, rich and poor, as well as the erosion of trust in institutions and experts.

It is likely that many of the alternative explanations of the pandemic, often called conspiracy theories, were further entrenched when vaccine policies were forcefully implemented in 2021, creating a strong confirmation bias that governments and corporate powers were acting in an authoritarian manner. Those who resist vaccine mandates and passports are more likely to have low trust in government and scientific institutions,2528 63 64 and these beliefs and distrust have likely grown due to the propensity of policies to justify social segregation, creating new forms of activism.

Furthermore, multiple social perceptions and logics about science, technology and corporate and government power have been grafted onto the public discussion about COVID-19 vaccines, specifically related to authoritarian biosurveillance capabilities.73

These include concerns about the adoption of implantable tracking devices (including microchips), digital IDs, the rise of social credit systems and the censorship of online information by technology companies and state security agencies. The COVID-19 pandemic happens to coincide with far-reaching technological advances that do provide the capability for new forms of mass state surveillance.74 75

For example, emerging biocompatible intradermal devices can be used to hold vaccine records,76 while multifunction implantable microchips (that can regulate building access and financial payments, much like cellphones) are now available on the market.77 Aspects of vaccine passport policies (dependent on QR codes) combined with these innovations as well as censorship by social media companies of vaccine clinical trial and safety issues from reputable sources like the BMJ78 have likely reinforced and exacerbated suspicion and distrust about the impartiality of public health guidance and vaccines.79

It is highly likely that reactance effects generated by current vaccine policies have increased the view that public health is influenced by powerful sociopolitical forces acting in the private interest, which may damage future social trust in pandemic response.

The political and legal effects of vaccine mandates, passports and restrictions

The erosion of civil liberties

The COVID-19 vaccine policies that we have outlined represent a broad interference with the rights of unvaccinated people. While some governments introduced mandates and passports through the democratic process (e.g., Switzerland, Austria, France), many policies were imposed as regulations, decrees, orders or directions under states of emergency and implemented in ways that allowed ad hoc juridical decisions and irregular and overpermissive private sector rules, with limited accountability or legal recourse to address rights violations.58

Vaccine passports risk enshrining discrimination based on perceived health status into law, undermining many rights of healthy individuals: indeed, unvaccinated but previously infected people may generally be at less risk of infection (and severe outcomes) than doubly vaccinated but infection-nave individuals.80 A weekly negative SARS-CoV-2 test is often seen as a compromise in lieu of full vaccination status, but this places additional burdens (including financial) on the unvaccinated while also risking reputational damage.

Employer-imposed mandates that do not provide reasonable accommodation (e.g., testing, relocation or reassignment of duties) or that require people to be vaccinated following prior infection even where employees can work remotely, arguably constitute a disproportionate imposition of a health intervention without workplace-related justification.81 Many countries have also tightened the ability to seek religious, medical or philosophical exemptions, open to unclear decision-making and political interference.82

Perhaps the most high-profile case to date involves the deportation of the top-ranked mens tennis player, Novak Djokovic, at the Australian Open 2022, despite having been granted a medical exemption on the basis of documented prior infection.83 While media outlets were quick at hinting about problems in his official submission, the Minister of Immigration accepted that he had a valid test result and that he posed only a very low risk to the health of Australians.84 Yet, the court ruled that it was reasonable for the Minister to conclude that Mr Djokovics presence could foster anti-vaccination sentiment and thus have a negative impact on vaccination and boosters.84 It endorsed Mr Djokovic characterisation as a threat to Australian civil order and public health.83 84

The case underlines concerns of vaccine mandates and passports as a tool for disproportionate policy that circumvents normative civil liberties and process.

There are also significant privacy issues with passports, which involve sharing medical information with strangers. Having set these population-wide passport precedents, it is conceivable that they could be expanded in the near future to include other personal health data including genetic tests and mental health records, which would create additional rights violations and discrimination based on biological status for employers, law enforcement, insurance companies, governments and tech companies.

COVID-19 vaccine passports have normalised the use of QR codes as a regulated entry requirement into social life; in France and Israel, double-vaccinated citizens lost their status when passports required a booster dose in 2021/2022.85 86 Technology companies interested in biosurveillance using artificial intelligence and facial recognition technology have obtained large contracts to implement vaccine passports and now have a financial interest in maintaining and expanding them.87

Political polarisation

COVID-19 vaccine policies have generated intense political debate, mass street protests and energised new populist movements with varied political views.20 21 2528 56 Studies show that while many support these policies, others view them as inherently coercive, discriminatory, disproportionate and counter to liberal values of bodily autonomy, freedom of choice and informed consent.2528 It is clear that current policies are divisive and unpopular with many, even vaccinated people, and that they have become a source for collective rage and anger, notably for those who have been fired from their jobs or isolated and barred from social life.

COVID-19 vaccine policies may influence upcoming elections. For instance, right-wing and populist parties in Germany (the Alternative for Germany), Canada (Peoples Party) and Austria (Freedom Party) have come out strongly against medical segregation. After implementing the worlds first population-wide mandatory vaccine policy in February 2022, Austria suspended it sixdays before police would impose fines (max. 3600), partially due to legal concerns, mass street protests and the fact that the rate of vaccination had not significantly improved (20% of adults remain unvaccinated).56 88

In 2022, the US Supreme Court struck down the Biden administrations federal vaccine mandate as unconstitutional,89 just as it came into effect for 80million workers (although upholding the mandate for HCWs); republicans had long criticised the mandates.90 91 In Martinique and Guadalupe, vaccine passports have led to months of political unrest and violent protests that threaten the stability of the French government.48 Pottinger92 argued that mandates and passports could trigger insurrection and civil war in South Africa.

Just as the smallpox vaccination mandates in 1850s Britain created the first anti-vax movement,93 the backlash against COVID-19 policies is energising a global network connected by modern communication technology against these measures. These backlashes may contribute to increased distrust of other vaccines and foster new forms of radicalisation and protest.

While mainstream news outlets have voiced concern about the rising anti-vaccination fervour among the far-right, and potential for violence,94 centre and left politicians have also used this rhetoric for their own agenda. In Canada, Prime Minister Trudeau used majority support for mandatory vaccination and passports to divide the conservative opposition in the 2021 federal election. The end to exemptions for unvaccinated truckers crossing the US-Canadian border precipitated the trucker freedom convoy protests in early 2022 in Canada, which led to weeks of protesters occupying streets outside parliament. The protest ended with the unprecedented invoking of the Emergencies Act, equivalent to martial law, which was heavily criticised by civil liberty organisations and included the freezing of protester bank accounts.95 96

In the USA, California and New York (Democrat-controlled states) have implemented COVID-19 vaccine passports for children while Florida, Georgia and Texas (Republican-controlled) are introducing legislation to remove childhood school vaccine mandates in general. Some medical freedom and anti-vaccination groups have made increasingly false and inflammatory claims, and business owners and employees requiring QR codes for entry have been targeted for abuse, in some cases.

In turn, pro-vaccine advocates have equated anti-mandate social groups as anti-vaxxers and even domestic terrorists, calling for government agencies and social media companies to strengthen censorship laws. Echo chambers have skewed the reasonableness of risk assessment of some pro-mandate individuals, who now fear that unvaccinated people are unsafe physically but also culturally despite the scientific evidence. Political polarisation and radicalisation both anti-mandate and pro-mandate will increase if punitive vaccine policies continue.

Disunity in global health governance

Current vaccine policies risk furthering disunity in global health governance. Despite the WHO stating in early 2022 that boosters would prolong the pandemic by contributing to vaccine hoarding and low supply,97 universities (including some global health departments) in wealthy countries have mandated boosters for low-risk healthy students and faculty,59 when vaccination rates remained low in many low/middle-income countries (LMICs).98

Efforts to pressure pharmaceutical companies (who developed vaccines with the support of publicly funded research money) to remove patent protections have proven unsuccessful.99 100 Pharmaceutical companies have ensured that the costs of adverse effects are borne by governments101 ; in turn, the worlds tens of millions of migrants and asylum-seekers may be denied COVID-19 vaccines because of legal liability issues.102

Simultaneously, some scientists are calling the unvaccinated (as a homogeneous group) the source of future variants (variant factories) fuelling inflammatory rhetoric103 that may have contributed to the heavily criticised reaction to close international borders to southern Africa during the spread of Omicron in late 2021. International travellers, especially from the global south, have been barred from travelling to high-income countries based on the type of received vaccine.

The rollout of vaccine passports and mandates is financially costly and diverts resources and focus away from other interventions. In Canada, $1 billion was pledged by the Trudeau government for vaccine passports104 and in New York State, the Excelsior Pass App-system developed by IBM will cost more than $27million.87

Importantly, focus on the unvaccinated as the cause of health system collapse diverts public attention away from global equity failures and deep structural challenges facing public health capacity in many countries. It absolves governments of attending to other strategies for opening schools and keeping public spaces safe, including improved ventilation and paid sick leave. The indiscriminate global adoption of current COVID-19 vaccine policies may also compromise national sovereignty by skewing health priorities in LMICs, taking budgets away from other important health priorities and disregarding public opinion a new form of vaccine colonialism.

Perhaps more significantly, it is possible that vaccination metrics become tied to international financial agreements and development loans and that pharmaceutical and technology companies influence the global adoption of passport systems and mandate policies for the current but also future pandemics.

Socioeconomic impacts

Increasing disparity and inequality

Historically, marginalised groups those facing economic challenges and racial and minority groups tend to have less confidence in vaccination programmes and are more likely to be distrustful.6366 6871 This raises the possibility that current vaccine policies may fuel existing inequity.105 A rapid policy briefing by the Nuffield Council on Bioethics106 emphasised that immunity passports could create coercive and stigmatising work environments and are more likely to compound than redress structural disadvantages and social stigmatisation.106

It is highly likely that mandates and passports have been implemented in ways that discriminate against disadvantaged groups including immigrants, the homeless, isolated elderly people, those with mental illness, specific cultural and religious groups, those in precarious living circumstances, and people with certain political views and values.

Moreover, communities who have historically been subject to state surveillance, segregation, structural racism, trauma or violence may be more likely to resist medical mandates. In Israel, reports suggest that Bedouin and Palestinian communities in the Occupied Palestinian Territory have faced major barriers to vaccine access, with more distrust of vaccination and bureaucratic barriers to accessing and using green passes even when vaccinated.58

Similar challenges have been raised among Europes Roma and in black communities in the UK and the USA.45 66 107 Altogether, rather than enhancing human agency and strengthening communities and social cohesion, many current vaccine policies including monthly fines for non-compliance (e.g., Greece and Austria) may work to disempower individuals and contribute to long-term psychosocial stress and disharmony.

Reduced health system capacity

The pandemic has created immense strain on health systems, contributing to disruptions in global immunisation programmes108 and burnout in healthcare and social care workers that risk worsening clinical outcomes for all patients. These trends may be exaggerated by the current policy push towards mandatory COVID-19 vaccination of healthcare/social care workers and firing of unvaccinated staff. The ethical arguments against these policies have been outlined by others.31 33 109

Despite these considerations, many countries may lose frontline staff due to mandates. By December 2021, despite the forthcoming imposition of a (later rescinded) vaccine mandate for patient-facing National Health Service (NHS) workers, 8% of medical practitioners in the UK (73000 people) remained unvaccinated.110 In late 2021, Quebec (Canada) dropped its proposed mandate for HCWs, citing the devastating labour shortage it would cause in hospital systems (3% of staff, or 14 000, were unvaccinated).111 Both cases created immense stress on already overburdened health staff and administrators, and were decried for their lack of clarity and clumpy policy process.112

Exclusion from work and social life

COVID-19 vaccination policies that disproportionately restrict peoples access to work, education, public transport and social life can be considered a violation of constitutional and human rights.113 The economic effects of restricting access to work may also have indirect implications for dependents of the unvaccinated. A survey in October 2021 in the USA found that 37% of unvaccinated participants (5% of participants overall) would leave their job if their employer required them to get a vaccine or get tested weekly; this rose to 70% of unvaccinated participants (9% of all participants) if weekly testing was not an option.114

Economic deprivation and parental stress resulting from restricted access to work and exclusion from social life may have long-term psychological and livelihood consequences on individuals, families and especially children.30 Commentators have also highlighted the potential impact of mandates in creating supply chain bottlenecks in certain commodities and with cross-border trade and argued that changing vaccine rules and regulations threaten to negatively impact overall economic recovery in some sectors of the economy including tourism.115

The integrity of science and public health

Erosion of key principles of public health ethics and law

Current vaccine policies may erode core principles of public health ethics. As some of those supporting mandates recognise,113 116 and contrary to the media portrayal that the unvaccinated are entirely free to decline, many COVID-19 vaccine policies clearly limit choice and the normal operation of informed consent. This has placed medical professionals in an awkward position, blurring the lines between voluntary and involuntary vaccination.

It is clear that many who are vaccinated did so because of the serious consequences of refusal, such as loss of employment and livelihood or access to social events and travel. We should pause to consider the extent to which current policies, and how they are implemented in clinical settings, sets a precedent for the erosion of informed consent into the future and impact the attitude of the medical profession to those who are reticent to undergo a specific medical procedure.

According to public health ethics, the principle of proportionality requires that the benefits of a public health intervention must be expected to outweigh the liberty restrictions and associated burdens.32 It would violate the proportionality principle to impose significant liberty restrictions (and/or harms) in exchange for trivial public health benefits, particularly when other options are available. Evidence shows that the efficacy of current COVID-19 vaccines on reducing transmission is limited and temporary,716 likely lower in younger age groups targeted for vaccine mandates and passports36 and that prior infection provides, roughly speaking, comparable benefit.18 31 80

The effectiveness of vaccine mandates in reducing transmission is likely to be smaller than many might have expected or have hoped for, and decrease over time. These issues have been widely discussed in the public arena, raising the idea that many current vaccine policies are no longer being guided by the best science but are rather being used to punish individuals who remain unvaccinated and to shape public opinion and compliance. Some governments have publicly admitted this much; in the words of French President Emmanuel Macron, the aim is to piss off [the unvaccinated] to the end. This is the strategy.117

Mandating a third dose for young boys to attend college or university in America has been widely discussed in the US media despite the lack of evidence for substantial clinical benefit,59 118 and with evidence of small but still significant risk of myocarditis that compounds with each dose.119121 Scandinavian countries have taken a precautionary and voluntary approach in their recommendations to the vaccination of children, with Swedish authorities stating that [because of] a low risk for serious disease for kids, we dont see any clear benefit with vaccinating them.122 This furthers the perception that current COVID-19 school vaccine mandates (e.g., in California) are disproportionate, especially as safety studies in young children remain relatively sparse.123

Proportionality is also a key condition from a constitutional and human rights perspective.113 124 125 The formal requirements of legal proportionality tests, which differ slightly depending on jurisdiction and context, generally reflect a balancing similar to the one in public health ethics. In part because of legally required restraint when it comes to assessing the reasonableness of complex policy interventions, several courts, human rights tribunals and committees, and labour arbitrators have upheld mandates as proportionate or made statements as to their legitimacy.113

This appears to have led to a broad presumption that mandates are legally unproblematic. But a common requirement of legal proportionality is that no other, less rights-restricting measures are available that can reasonably achieve the key public health goal. Accommodation of the workplace, or alternatives to vaccination such as testing, should be and have often been identified by courts, tribunals and arbitrators, as being a core element of the legality of mandates.81 113 124 126 Mandates imposing unconditional vaccination, those ignoring the role of prior infection, and those ignoring a shifting risk/benefit balance depending on specific populations, should be considered suspect from a legal proportionality perspective.

When members of the public perceive mandates to be ethically and legally problematic and in violation of established norms of informed consent and proportionality, this will erode trust in public health and scientific institutions and even courts that endorsed or actively promoted such policies. This presents a challenging paradox for experts and authorities: will pro-mandate scientists and organisations come to acknowledge that mandates and passports were disproportionate policy responses?

One key aspect of building trust in science and public health involves the open acknowledgement of when experts are wrong and when policies were misguided; however, it appears that many officials have doubled down in their narratives. This may undermine key ethical and legal criteria for policy and have damaging effects on the integrity of public health itself.

Erosion of trust in regulatory oversight

COVID-19 vaccines were developed in record time to meet an urgent public health need and have been accepted by billions of people, preventing deaths, severe hospitalisation and long-term sequelae from SARS-CoV-2.36 COVID-19 vaccines have also generated at least $100billion profit for pharmaceutical companies, especially Pfizer.127 Has the acceptance of mandates and passports and the rhetoric around anti-vaxxers contributed to a cultural shift in norms of scientific and corporate transparency and accountability?

Governments have refused to disclose the details of contracts with manufacturers, including for additional doses or next-generation vaccines.99 Vaccines are typically not approved until 2years of follow-up data are gathered,2 but given the urgency of the COVID-19 pandemic and international harmonisation of new agile regulations, the novel mRNA COVID-19 vaccines were placed into emergency use in Europe and North America in late 2020.128

There is concern that, in the fog of crisis, vaccine policy is being driven by vaccine manufacturers rather than independent scientific and regulatory review. For example, in April 2021, Moderna informed their investors that they were expecting a robust variant booster market as a source of profits. Similarly, Pfizer CEO Albert Bourla suggested that a fourth dose of vaccine would be necessary, without any clinical trial data or independent evaluation that the benefits of subsequent doses outweigh any risks, nor consideration of the changing clinical dynamics with the Omicron variant.118 This only adds to distrust over decision-making around vaccine use and ensuing mandates.

The public is aware of the history of corporate pharmaceutical malfeasance and criminal and civil settlements in the billions of dollars, including with Pfizer, in part resulting from marketing practices and misrepresentation of safety and efficacy of medicines.50 51 129

The nature of mandates, passports and restrictions has increased public demands for scientific accountability and transparency shown to be fundamental to building long-term confidence in vaccination.130 This has increased the need to diligently track all safety signals for adverse effects in specific demographics131 and explore trends in overall population mortality and potential non-specific effects.132 However, the original clinical trial data remain unavailable for independent scientific scrutiny50 51; a whistleblower raised important concerns about data integrity and regulatory oversight practices at a contract company helping with Pfizers clinical trials in the USA.133

After a Freedom of Information Act (FOIA) request by a civil society group, the US Food and Drug Administration (FDA) requested (ultimately denied by a federal judge) 75 years to fully release internal documents and communications related to the regulatory process between FDA and Pfizer. In September 2021, an FDA advisory committee voted 16-2 against boosting healthy young adults in the USA but was over-ridden by the White House and CDC, leading to the resignation of two top FDA vaccine experts.118

Such efforts have only increased the perception that regulatory agencies are captured by industry and would conveniently ignore a higher than usual adverse effect ratio to control the pandemic. Concerns have been raised about the lack of due process in vaccine injury compensation claims for the COVID-19 vaccines,100 which are to be borne by governments and not pharmaceutical companies. A video of a US congressional roundtable on COVID-19 vaccine adverse events with medically confirmed vaccine-injured individuals from the original clinical trials, a US military clinician and Peter Doshi (senior editor of the BMJ) was permanently removed by YouTube.134

These practices do not reinforce confidence that authorities are being transparent or applying optimal standards for regulatory safety, efficacy and quality for these novel vaccines standards which should arguably be more stringent given the legal precedent for mandates and passports.

Conclusion

The adoption of new vaccination policies has provoked backlash, resistance and polarisation. It is important to emphasise that these policies are not viewed as incentives or nudges by substantial proportions of populations2528 41 45 especially in marginalised, underserved or low COVID-19-risk groups. Denying individuals education, livelihoods, medical care or social life unless they get vaccinated especially in light of the limitations with the current vaccines is arguably in tension with constitutional and bioethical principles, especially in liberal democracies.3033

While public support consolidated behind these policies in many countries, we should acknowledge that ethical frameworks were designed to ensure that rights and liberties are respected even during public health emergencies.

The Unintended Consequences of COVID-19 Vaccine Policy The Wire Science - The Wire Science

Health System Warns Exemptions to COVID Vaccines May Expire With New Options – Medpage Today

September 10, 2022

The Froedtert Health network in Wisconsin has sent a clear message to employees claiming religious exemptions from COVID-19 vaccination: with an alternative to mRNA vaccines now available, get vaccinated or resign.

In an email to a Froedtert staff member obtained by WTMJ-TV, the health network's COVID-19 Vaccine Religious Exemption Review Committee wrote, "Your original exemption submission and additional documentation you provided do not meet the criteria of explaining your sincerely held religious belief that conflicts with receiving the COVID-19 vaccine, including the new Novavax vaccine."

The religious exemption will not be upheld, despite additional comments provided that "related to opinions or non-factual information," the committee added. If the staff member does not get a first dose by September 21, they will be "considered voluntarily resigned."

The move by Froedtert, which is affiliated with the Medical College of Wisconsin in Milwaukee, signals a blow to vaccine holdouts in the workplace, including healthcare providers, who have argued their religion prevents them from getting vaccinated.

While the Pfizer and Moderna vaccines are mRNA-based, Novavax is protein-based. Those who requested religious exemptions to their work or school policies have often cited the use of fetal material in mRNA vaccines or in their development, though neither Novavax nor the Pfizer and Moderna vaccines contain fetal tissue or DNA. However, it has been reported that laboratory-replicated fetal cell lines, some originating from abortions decades ago, have been used in the testing of mRNA vaccines.

Dorit Reiss, PhD, a professor at the University of California Hastings College of the Law in San Francisco, who has researched religious exemptions from vaccines, told MedPage Today it was only a matter of time before some employers, including hospitals, started to enforce vaccination policies after Novavax was authorized for use in August.

"I've said publicly before that I think Novavax does change the situation in relation to arguments about cell lines," she said. "This is the first I've heard of an employer actually moving on it."

An emailed statement from Froedtert to MedPage Today said, in part, "This protein-based vaccination option eliminates conflicts for those staff with religious or medical exemptions caused by mRNA-based vaccines and other concerns. Since those staff are now eligible for a vaccination that does not conflict with their religious beliefs or medical situation, their exemption will expire."

The health network said that the rule will affect less than 1% of their staff, and that "impacted employees" were given a chance to apply for another exemption before previous ones expired, noting they will uphold "valid medical exemptions and sincerely held religious exemptions."

Reiss said of the many claims to back up religious exemptions she's come across, the fetal cell line argument was perhaps the most common, partially because it might curry favor from pro-life judges. "If they can piggyback on the abortion debate, they're more likely to win" in a dispute, she said. But other reasons, like the claim that some religions require blood to be free of contamination, have also been used.

Some vocal opponents of vaccine requirements may have anticipated the post-Novavax repercussions, and urged their followers to use other reasons to back up their religious objections, Reiss said.

For example, Cait Corrigan, a Boston University theology student behind a group called Students Against Mandates, posted an online outline to the group's website with tips for "successful" religious exemption letters, writing, "Note you can write about aborted fetal tissue ... but this is not enough! (You must talk about the issue of Blood in the vaccines, being made in the Image of God, etc.)" (MedPage Today could not confirm whether Corrigan is still a student at Boston University.)

But neither these types of arguments nor religious beliefs are likely to hold up in most courts, according to Reiss and other experts. "The standard for vaccine mandates in the workplace is, you can refuse an exemption if it's an undue burden, like the burden of not having vaccinated employees at a hospital," she said.

And though objections to vaccination itself may be sincere, "for most of them, I think it's about safety concerns, many of them created by misinformation," Reiss noted. "For most of them, the religion is a cover for that concern."

Does Moderna’s vaccine IP lawsuit herald the end of the pandemic? – Medical Marketing and Media

September 10, 2022

The SARS-CoV2 virus has proven to be nothing if not tenacious. While its virulence has been tempered by vaccines, boosters and treatments, it remains a force to be reckoned with. And even though many have tried to predict the pandemics eventual conclusion, lets just say that reports of the coronavirus death have been greatly exaggerated.

Given that backdrop, more than a few pundits must have raised an eyebrow upon hearing that, with its recent COVID-vaccine intellectual property lawsuit against Pfizer and BioNTech, Moderna was, in effect, declaring the end of the pandemic.

In the suit, filed in the U.S. District Court for the District of Massachusetts and the Regional Court of Dsseldorf in Germany, Moderna asserts that multiple patents were infringed upon. One involves chemical modifications to the mRNA molecule, which reduce the bodys immune response against the mRNA itself. Another involves mRNA encoding for a full-length coronavirus spike protein.

Together they form the foundation of the mRNA platform in Spikevax, Modernas COVID-19 shot. The technologies underlying the patents were invented by the company years before the pandemic began. Moderna alleges that Pfizer and BioNTech ultimately chose to adopt the same vaccine design and chemical modification for their COVID-19 shot, Comirnaty.

Not surprisingly, Moderna is seeking monetary damages. But the timing of the lawsuit is what has piqued the broader industrys curiosity.

Back in October 2020, Moderna issued a statement on IP-related matters. In it, the company acknowledged there are other COVID-19 vaccines in development that may use Moderna-patented technologies, but vowed not to enforce its COVID-19 related patents against makers of those other vaccines while the pandemic continues.

Then in March of this year, Moderna issued an updated pledge, saying in effect that the situation had changed. Its August 26 lawsuit, then, was a de facto recognition of the end of the COVID-19 pandemic by [Moderna], as the company previously signaled reluctance to pursue patent litigation while the pandemic was ongoing, analysts from SVB Securities observed in a research note.

Modernas complaint cites the voluntary pledge it made more than two years ago. It goes on to explain that, by early 2022, The collective fight against COVID-19 had entered a new endemic phase and vaccine supply was no longer a barrier to access in many parts of the world, including the United States. In view of these developments, Moderna announced on March 7, 2022, that it expected companies such as Pfizer and BioNTech to respect Modernas intellectual property and would consider a commercially reasonable license should they request one.

To date, neither Pfizer nor BioNTech has requested a license. So what happens now that a competitor is asserting that it played a role in the creation of Pfizers shot, which the drugmaker expects will bring in $32 billion in global revenue this year?

The way forward is complicated by the fact that mRNA vaccines rely on a host of technologies developed by multiple companies, non-profit labs and government institutions. Parsing ownership will be a thorny process.

Meanwhile, in light of the slowdown in FDA approvals, no one wants to undercut these proven cash cows. Moderna says that it isnt looking to remove Comirnaty from the market. And the various companies suing Moderna for patent infringement, which include Arbutus Biopharma/Genevant Sciences and Alnylam Pharma, arent looking to get in the way of Spikevaxs future sales, either.

Such disputes are typically resolved via a one-time royalty payment. If the history of IP kerfuffles among companies in the oligonucleotide space is a guide, the SVB team wrote, The most likely outcome would be modest royalties paid by both companies, usually in the low single digits percentage-wise.

Moderna is only suing for Comirnaty revenue Pfizer and BioNTech realized after March 8, 2022, as it said it values a speedy end to the pandemic over the potential for profits. That would imply a modest royalty payment.

Law firms for the parties, on the other hand, stand to gain much more. Legal teams for Pfizer and BioNTech are likely to weaponize their own patent portfolio and pursue a path of delay and deny, which could result in the dispute taking years to resolve in court.

Legal scholars say Modernas patent case may depend in part on whether were past the pandemic phase of COVID-19. With 400 people dying every day and current case counts sitting at around 90,000 per day and 40,000 more currently hospitalized in American hospitals one could argue that we are very much not. The World Health Organization certainly hasnt downgraded the pandemic status yet.

And even though Moderna thinks its March 2020 pledge has expired, the firms initial promise may still be binding. Assuming Pfizer/BioNTech were justified in relying on their rivals 2020 vow when they developed and priced Comirnaty, Moderna could be prevented from reneging (and from enforcing its patents) under a legal doctrine known as promissory estoppel.

Why is Moderna willing to take the chance of its suit backfiring for such a small amount? Probably because of the potential of mRNA as a platform technology. Determining who owns the licenses now could result in larger payouts down the line.

But Moderna may not be able to simply invalidate prior patent assurances. As long as the WHO still maintains that the COVID-19 pandemic is in force, it aint over til its over.

Study: COVID-19 Vaccine Prevented Approximately 27 Million Infections in US Adults – Pharmacy Times

September 10, 2022

The percentage of infections, hospitalizations, and deaths that were prevented from COVID-19 vaccination increased with greater vaccine coverage, according to a recent study.

Based on a review of the data, investigators observed that the US COVID-19 vaccination program was successful in preventing millions of infections, deaths, and hospitalizations from SARS-CoV-2 in adults in the United States. Specifically, the investigators found that individuals who received a complete vaccine serieseither 2 doses of BNT162b2 or mRNA-1273, or 1 dose of JNJ-78436735was estimated to prevent 30% of all future COVID-19 infections. Vaccination was also found to reduce 33% of all expected hospitalizations and 34% of deaths in individuals aged 18 and older.

COVID-19 vaccination in the US has provided substantial protection against infections, hospitalizations, and deaths among those who have been vaccinated, wrote the study authors in their report published in JAMA Network Open. Vaccination is an effective public health intervention with demonstrable impact, which will be critical in combination with nonpharmaceutical interventions to mitigate the COVID-19 pandemic.

During the study, investigators aimed to estimate the number of SARS-CoV-2 infections and associated hospitalizations and deaths prevented due to the COVID-19 vaccine in US adults. At the start, the investigators first estimated the burden of COVID-19 by age group, month, and state in the United States using a multiplier model. After gathering data on estimated COVID-19 hospitalizations, the investigators then estimated the number of infections and deaths associated with the virus.

To determine the estimated number of vaccinated individuals in the United States, the investigators used CDC data and calculated the numbers based on age group, month, state, and vaccine type. The results of this analysis indicated that approximately 27 million infections were prevented because of the COVID-19 vaccine. Among those who were fully vaccinated, approximately 235,000 deaths were prevented during the 9-month study period. The vaccine also protected against an even larger 1.6 million hospitalizations in adults aged 18 years and older.

Additionally, the US COVID-19 vaccination program had the greatest impact in terms of averting severe disease in older adults. These age groups not only have the highest rates of hospitalizations and deaths, but they also have the highest rate of vaccine coverage, according to investigators.

The investigating team also observed that the northeast region of the United States likely experienced the most prevention against infections, hospitalizations, and deaths from COVID-19. This estimate was based on the higher rates of vaccination in this population compared to other US regions.

The investigators also noted that the study findings had the limitation of not taking into account reduced infections, hospitalizations, or deaths in unvaccinated peoplenor did the findings account for the benefits experienced by partially-vaccinated individuals. Investigators also admitted that they could have underestimated both the burden of severe outcomes in unvaccinated people and accurate hospitalizations caused by COVID-19 infection.

However, investigators did note that the data showed both direct and long-term benefits from a full vaccination. Additionally, the study authors noted that they hope future research will be focused on estimating the impact of vaccination in individuals younger than age 18 years, as well as assess the benefits of partial vaccination, indirect benefits of vaccination on disease transmission, and the impact of additional primary or booster doses.

The associations between vaccination status, type, and time since vaccination with lineage identity during the emergence of new SARS-CoV-2 variants -…

September 7, 2022

In a recent study published in Emerging Infectious Diseases, researchers assessed the association between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strains and patient age, coronavirus disease 2019 (COVID-19) vaccination status, vaccine type, and days elapsed since the most recent vaccination among New York residents.

Studies have reported higher transmissibility and immune-evasiveness of novel SARS-CoV-2 strains such as Omicron and Delta compared to previously circulating strains. The increased number of mutations in recent strains greatly enhance the infectivity and attenuate the immune protection conferred by existing COVID-19 vaccines, monoclonal antibodies (mAbs), and convalescent sera transfusions. Factors such as patient age, type, vaccination status, and the duration elapsed since the most recent vaccination may also affect COVID-19 vaccine efficacy.

In the present case-control study, researchers performed a matched case-control analysis to assess the differences in vaccine effectiveness for SARS-CoV-2 strains such as Delta and Omicron associated with variation in vaccination status, vaccine type, time since vaccination, and patient age among New York residents.

A viral genomic sequence dataset linked with demographic and vaccination data obtained from records of the communicable disease electronic surveillance system and New York state immunization information system, respectively, was used for the analysis. The case patient group comprised individuals infected with the emerging SARS-CoV-2 strain, whereas the control group comprised individuals infected with any other SARS-CoV-2 strain.

Respiratory swabs that were found to be SARS-CoV-2-positive by real-time reverse transcription polymerase chain reaction (RT-PCR) were subjected to whole-genome sequencing (WGS) analysis based on the global initiative on sharing all influenza data (GISAID) database sequences. An individual was regarded unvaccinated if the specimen was obtained before COVID-19 vaccinations, vaccinated if the specimen was obtained >2 weeks post-prime vaccination completion (Janssen vaccines initial dose and Moderna or Pfizer vaccines subsequent dose), and booster vaccinated if the specimen was obtained any time post-booster dose administration of any type of COVID-19 vaccine.

Omicron emergence was analyzed between 28 November 2021 and 24 January 2022, including 1439 case patients (individuals with Omicron infections) and 728 controls (individuals with Delta variant, B.1.617.2, or AY strain infections). Case patients were matched to controls based on the date of specimen collection (6 days), location (New York state economic areas), patient sex, and age.

Delta emergence was analyzed between 19 March 2021 and 15 August 2021, with 603 case patients and 1,816 controls, respectively. The control group comprised individuals infected with B.1.1.7 and Q.4 Alpha (62%), B.1.526 Iota (20%), P.1.X Gamma (3.5%), and B.1.351.X Beta (1.0%). Logistic regression modeling was used with models selected based on the Akaike information criterion (AIC) scores, and odds ratios (ORs) were calculated.

The team excluded 261 partially vaccinated individuals (whose specimens were obtained between the first dose and two weeks post-completion of vaccination with Moderna (n=90) and or Pfizer vaccines (n=171). In addition, individuals were excluded if they had received the booster (third) vaccination (e.g., potentially immunosuppressed individuals) due to small sample sizes (58 individuals who received booster doses within 135 days of the second vaccination) and different vaccination histories.

Most of the case-control pair individuals for Omicron infections were aged between 18 years and 69 years and resided in the Mid-Hudson and Capital areas. Among cases and controls, 22% and eight percent of individuals had been administered booster vaccinations, respectively. The corresponding percentages for unvaccinated individuals were 30% and 57%, respectively.

The sample population for Pfizer, Moderna, and Janssen vaccinations comprised 177, 109, and 22, respectively. Omicron infections showed the greatest associations with the status of prime vaccinations and booster vaccinations, with OR values of 3.1 and 6.7, respectively. On removing patient age as a criterion for matching (309 case-control pairs), lower age was predictive of Omicron infections (OR 0.96) and OR values for the status of prime vaccination (OR 4.8) and third (booster) vaccination (OR 39) were greater compared to those obtained previously.

On considering only vaccinated individuals (129 case-control pairs), the odds of Omicron infection reduced with a greater duration of days elapsed post-the most recent vaccination (OR 0.99). A trend toward lower chances of Omicron infections post-Janssen vaccinations was observed with borderline significance [OR 0.4, in relation to any messenger ribonucleic acid (mRNA) vaccination].

Among the case-patient/control pairs for Delta infections (55 case-control pairs), most of the individuals were aged between 18 years and 69 years (75%) and resided in Long Island, Mid-Hudson, and Finger Lakes areas (89%). About 62% and 75% of cases and controls were unvaccinated, respectively. Delta infections showed the greatest associations with vaccination status (OR 2.4).

The vaccine type and days elapsed since the most recent vaccination showed no significant association with the odds of Delta infections. Removing age as a matching criterion showed that the odds of Delta infections were 7.3-fold higher among individuals who received Pfizer vaccinations compared to unvaccinated individuals. The odds were also higher for Moderna vaccines (2.0-fold) and Janssen vaccines (0.5-fold), although not statistically significant individually.

Overall, the study findings showed that novel SARS-CoV-2 strains have greater potential than previously circulating strains to cause vaccine breakthrough infections. Infections among completely vaccinated and booster vaccinated individuals were associated significantly with Omicron. However, the odds of being infected with Omicron in relation to Delta reduced with advancing age. An identical but non-significant trend was noted with vaccination status during Delta predominance.
