Category: Covid-19 Vaccine

The U.S. is home to the worlds biggest and best-known pharmaceutical companies. But China is giving the U.S. a run for its money in the race to develop a vaccine for Covid-19a feat that would instantly change the dynamics of the fight against the deadly virus, and the geopolitical competition between the U.S. and China.

Beijings government, including its military and several state-backed firms, has committed hundreds of millions of dollars and cleared regulatory barriers to accelerate research and development. Even before...

In Race for Covid-19 Vaccine, China Tries for a Coup - The Wall Street Journal

COVID-19 vaccine not coming anytime soon: Health professor from Italy  |  Photo Credit: iStock Images

New Delhi: It is not possible to develop a vaccine for Covid-19 soon, as the RNA virus changes very quickly and this makes it difficult to create a good vaccine, says Claudio Colosio Unimi Professor, Department of Health Sciences University of Milan, Italy.

Claudio as the Director, Occupational Health Unit of the Hospitals Saints Paolo and Carlo of Milano, has been extensively handling the Covid-19 pandemic. When queried about a vaccine still not appearing on the horizon, Claudio said there is no vaccine for HIV infection yet (and people still survive).

And is there a possibility to develop a vaccine for Covid-19, and how soon is it possible?

Claudio replied "Not very soon. RNA viruses change very quickly and this makes it difficult to create a good vaccine."

Elaborating on the Italian experience of Covid-19, -- a possibility the population has developed herd immunity after experiencing the viral infection attack for close to 6 months -- Claudio said "No. Today the rate of immunization is in the order, depending on the areas, of 2-15 per cent. Very far from herd immunity."

Italy was worst hit by coronavirus, currently the number of cases have reduced drastically from 5,000 to less than 300 cases a day.

Comparatively, India is just where Italy was months back. More than 9,000 cases were reported on Thursday. It also posted over 5,000 for over two weeks, before crossing 6,000, then 7,000 and 8,000 in rapid succession.

On suggestions for India from his experience in Italy, Claudio said: "Doing the big sacrifice of locking down if possible.

"Otherwise mandatory mask: surgical mask is ok for most situations. However, I understand how difficult this is in India.

"Finally, social distancing. Otherwise it would be very difficult to stop the chain of infection. You should be satisfied when the number of subjects infected by a single coronavirus subject will be under 1."

Citing the Covid-19 study at the University of Milan, Claudio said: "We are studying the trends of infection among healthcare workers and whether the approaches are adequate to avoid the spreading of the disease ("contact tracing")."

Queried on the increasing levels of pollution, especially in Indian context which has many polluted cities, aiding the spread of coronavirus, Claudio said "There is not any evidence of this. Just only a hypothesis. I don't trust it."

When asked, if the current trend of number cases would lead India in the US, UK direction, where the viral infection ran havoc claiming thousands of lives, Claudio said "This is something we cannot anticipate from here. For sure the risk is highest in the most populated regions, and in any place where social distancing is difficult. And India suffers both these risk determinants!"

Responding to a query on Italy's efforts in bringing down deaths due to Covid-19, (according to WHO since May 25 Italy has reported less than 100 deaths a day), Claudio said "With social distancing and removing these people (vulnerable group) from the more risky jobs, for example some departments in the hospitals for health care workers.

"A good solution requires smart job done."

COVID-19 vaccine not coming anytime soon: Health professor from Italy - Times Now

Even as scientists race to develop a COVID-19 vaccine, experts acknowledge that children could be among the last members of society to be vaccinated.

At least 10 vaccines are being tested in people across the globe, with the United States' top infectious disease doctor, Anthony Fauci, optimistically estimating we could have a viable vaccine by early 2021. While preliminary data on these vaccines has been encouraging, children have been excluded from early studies.

Fauci told ABC News it's possible that studies in children might "catch up" to those in adults, if they are done correctly.

"There is no reason not to believe that [a vaccine] wouldn't be available simultaneously for adults and children," Fauci said.

But other vaccine experts interviewed by ABC News said studies among children could take much longer to complete, and a hard look at the timeline of ongoing vaccine trials raises questions about whether families can expect their children to be vaccinated at some point in the upcoming academic school year.

"Children will be vaccinated, in time," said Dr. Paul Offit, director of the Vaccine Education Center at the Children's Hospital of Philadelphia, who sits on the Food and Drug Administration's vaccine advisory committee.

"To date, my sense is that children are not part of these initial studies," Offit added. "It would be unfathomable giving children a vaccine that has not been adequately tested in children."

Work on a COVID-19 vaccine is underway at American biotechnology company Moderna in Massachusetts. Moderna plans to start phase II of its vaccine trials soon and phase III in the summer of 2020.

The process for testing a COVID-19 vaccine in children could take "extra months and maybe years longer," according to Paul Duprex, PhD, Director of the Center for Vaccine Research and professor of microbiology and molecular genetics at the University of Pittsburgh.

Throughout history, scientists have constantly been reminded that children are not simply small adults. Their bodies and immune systems work differently than adults, so they need to be studied separately -- preferably after safety has already been well-established in adults.

"Every person is special, but kids are especially special," said Duprex. "They are our charges. The emotional baggage that goes with something going wrong in clinical trials involving kids -- and I'm not saying adults are not important -- it's just different."

For now, vaccine trials remain laser-focused on members of society deemed to have the highest risk, such as front-line workers and adults. Although some groups have announced their intention to test vaccines in children, ABC News contacted four vaccine groups and none said they have actually started studies in children yet.

Typically, vaccines are tested in a stepwise approach: phase 1 for safety, phase 2 to start testing effectiveness and a massive phase 3 study with thousands of people.

The pharmaceutical company Pfizer told ABC News it will advance a vaccine into children once positive data from phases 1 and 2 is available in adults. Another company, Inovio said it plans "to assess pediatric populations in the future."

The University of Oxford, which has partnered with the pharmaceutical company AstraZeneca, is one of the few vaccine groups that has announced formal plans to start testing in children.

But a University spokesperson told ABC News that children will not be injected right away, and will only be given the vaccine once "all of the adults studies are moving along and have generated sufficient safety data."

In the United States, the National Institute of Allergy and Infectious Diseases (NIAID), which is collaborating with pharmaceutical companies for vaccine trials, told ABC News the agency would continue to work with CDC to better understand how the virus affects children.

In a statement, the agency said: "We will continue to plan for follow-on clinical trials to include younger age groups so such trials can commence if epidemiological CDC data indicate a need to test COVID-19 vaccines in children."

With vaccine skepticism on the rise, experts stressed that it will be important to proceed with caution. According to an ABC News/Washington Post poll, 27% of American adults said they were not inclined to get a vaccine -- even if it was available for free.

With any new vaccine, the ethical thing to do is test for safety in healthy adults first, and then begin testing it among people who need it the most, explained Jennifer Miller, Ph.D., an assistant professor at Yale School of Medicine and founder of Bioethics International and the Good Pharma Scorecard.

For COVID-19, that means older adults, front-line workers and people with underlying medical conditions. Children are far less likely to die of this disease.

"About 2% of the cases reported are in the pediatric population," said Dr. David Kimberlin, professor and co-director of the Division of Pediatric Infectious Diseases at the University of Alabama-Birmingham.

"It's about minimizing risks, it's about informed consent and it's about the population that needs it the most," Miller said.

Minimizing risk is important, especially when it comes to children and vaccines, experts agreed.

Very rarely have candidate vaccines caused a disease to become more severe when the individual is subsequently exposed to the natural infection.

This happened in 1966, when a chemically inactivated vaccine candidate for a childhood lung disease called RSV led to the death of several children. "That tragic event set the RSV vaccine field back decades," said Duprex. "In fact, there still is no licensed RSV vaccine."

Fauci proposed that children might be tested in a so-called "bridging study," in which children are studied in a Phase I trial to ensure the vaccine is safe, and then quickly folded into a large phase 3 study.

Other experts noted it's theoretically possible that studies in children could "catch up" to those in adults, though unprecedented. But even if we do not have a vaccine for children right away, that doesn't necessarily mean children will have to remain socially distant indefinitely.

Eventually, widespread vaccination of adults could end up protecting children thanks to "herd immunity," which is when enough people are vaccinated to snuff out an ongoing chain of infections.

"Usually it's the older way around -- vaccinating children protects older adults," Kimberlin said. But in the case of COVID-19, if we find a successful vaccine and most adults become immune to the virus, "parents could still very legitimately look at that as a win for children because it's a win for society."

In the race for a vaccine, children may be last to be vaccinated - ABC News

The novel coronavirus crisis has introduced us a to a different world one with a new normal. Temperature checks, social distancing, masks, work-from-home and distance learning are some of the new norms that all of us need to embrace and adapt to. Governments have imposed strict measures in order to break the chain of infections, this includes travel restrictions and citywide lockdowns. The COVID-19 virus is not only a health threat, but has also decimated livelihoods, local businesses and the economy in general.

It is believed that until an effective vaccine is found,the new normal is likely to stay indefinitely. This can be seen from the recent announcement made by the President of the Philippines, Rodrigo Duterte who said that he will not allow face to face classes in schools until a COVID-19 vaccine is made available.

To date, over 6.2 million people have been infected with the COVID-19 virus and total deaths recorded have already passed the 370,000 mark. Scientists and pharmaceutical giants around the world from ASEAN member state, Thailandto European countries are currently working at breakneck speed to develop a vaccine for the disease since it first emerged in Wuhan, China.

According to the Global Alliance for Vaccines and Immunisation (GAVI), as of 11 May, there are more than 102 candidate vaccines that researchers are working on, of which at least nine are now being tested in clinical trials on humans.

So, what are some of the latest developments in the race to find a COVID-19 vaccine?

When candidate vaccines make it to human clinical trials, they first go through Phase 1 trials primarily to test the vaccines safety, determine dosages and identify any potential side effects in a small number of people. Phase 2 trials further explore safety and start to investigate efficacy on larger groups. The final stage, Phase 3 trials, which few vaccines ever make it to, are much larger, involving thousands or tens of thousands of people, to confirm and assess the effectiveness of the vaccine and test whether there are any rare side effects that only show up in large groups, stated GAVI.

Some candidate vaccines that are in Phase 2 include the Beijing Institute of Biological Products and Wuhan Institute of Biological Products, which both belong to Chinas state-run Sinopharm Group. Others include BioNtechs MRNA Vaccine in Germany and the University of Oxfords Viral Vector Vaccinein the United Kingdom (UK).

There is good news from the Beijing Institute of Biological Products, as it was recently reported that the vaccine jointly developed by the organisation and China National Biotec Group Co. has completed Phase 2 testing and may be ready for the market at the end of 2020 or early next year, according to a report published in the official WeChat account of the state-owned Assets Supervision and Administration Commission.

Nevertheless, Phase 3 would not be endured without challenges. Media reports have stated that the final stage of testing needs to be done in a place where the virus is still spreading rapidly, and Chinas cases seem to have been plummeting every day. Other than that, a viable vaccine needs massive production capabilities in order to meet global distribution demands.

Although many are hoping for a vaccine or a cure to be deployed very soon, "unfortunately, we really do not know which vaccine will work and whether there will be one at all. If we're lucky, we'll receive indications in autumn as to (a potential vaccine's) effectiveness," GAVI head Seth Berkley told a Swiss newspaper.

There are other concerns regarding the search for a vaccine; domestic interests and that a vaccine would first go to high-income countries.

Based on a statement by GAVI, when a COVID-19 vaccine is ready, scaling-up manufacturing capacity to produce enough for the world will be a difficult task. Even with the current investment into greater manufacturing capacity, it is not enough to vaccinate everyone straightaway.

So, when vaccines do become available, it will most likely be those at greatest risk of the coronavirus health workers, older people and those with underlying conditions, such as diabetes that will be prioritised first.

Dr Koh Mia Tuang, a consultant paediatrician with a subspecialty in paediatric infectious diseases at the University of Malayas Medical Centre in Malaysia recently wrote an article in the local media discussing the affordability of a COVID-19 vaccine when it is eventually made available.

There is no guarantee that less developed countries will be able to afford and have access to the vaccine, explained Dr Koh.

Even now, certain more powerful and rich nations have an understanding with potential vaccine manufacturers to have exclusive rights to the first vaccines, which will likely culminate in an artificial global vaccine shortage, he added.

At the moment, drugs such as antivirals lopinavir/ritonavir (for HIV treatment) and remdesivir (originally developed for Ebola) have been rebranded as temporary treatments for COVID-19 patients with severe conditions.

Until a viable, safe and effective vaccine is found, it is important to adhere to guidelines and safety measures provided by health authorities. In reference to the popular proverb prevention is better than cure, and as advised by many medical specialists such as Dr Koh Mia Tuang himself: stay healthy, practice social distancing and diligent handwashing, wear face masks when possible and avoid crowded areas as preventive measures against the COVID-19 coronavirus.

COVID-19: SARS-CoV-2 mutation study from Gujarat to help in development of coronavirus vaccine  |  Photo Credit: Reuters

New Delhi: The novel coronavirus was discovered last year, in the last week of December. Since almost five months, a lot of new information on the virus has come in. According to a study conducted in Gujarat, analysis of mutations across the SARS-CoV-2 genome may help in the development of a single COVID-19 vaccine, says Professor Chaitanya G. Joshi, Director at Gujarat Biotechnology Research Centre (GBRC), reported news agency IANS.

As already known, the coronavirus seems to be mutating at a high speed, and it was reported that the virulent L-strain of the coronavirus is responsible for high mortality, though no conclusive evidence of the same has been found as yet. It was also found that the A2A type mutation, which has become predominant, also increases the efficiency of the entry of the virus, into the human body through cells.

"In the samples sent to us so far, we have seen four S strains and the rest all are L-strains. We have analyzed nearly 150 samples. At this stage, it is not correct to attribute deaths to L-strain. Various factors are involved in death due to this viral infection. The virus is mutating and it has already spread into many parts of the country. Analysis of mutation will help in vaccine development," said Joshi, reported the news agency.

Mr Joshi further added that the vaccine will undergo testing and trials, to establish its efficacy. Hinting that developing a vaccine is no cake-walk, Joshi said that some diseases get a vaccine while some don't, giving an example of malaria and HIV, which do not have a vaccine yet, even after being around for years.

However, the analysis of the genome will definitely help in the development of the vaccine, as well as treatment for the viral infection, Joshi assured.

The COVID-19 cases in India cross the 2 lakh mark today, with more than 5800 deaths. The toll of confirmed cases all over the world stands at 6.8 million. More than 17,000 cases have been reported from Gujarat alone. There exists no specific cure or vaccine for the novel coronavirus. Researchers from all over the world, including India, are racing towards finding an effective vaccine against the recently discovered virus. India is currently developing 11 vaccines against COVID-19.

COVID-19: SARS-CoV-2 mutation study from Gujarat to help in development of coronavirus vaccine - Times Now

Washington, D.C., June 02, 2020 (GLOBE NEWSWIRE) -- As the COVID-19 vaccine race accelerates, experts recognize that the challenge will not end with the development of a vaccine. The extraordinary effort to make a vaccine available across the globe will only be effective if the majority of people achieve immunity through vaccination. Meeting the Challenge of Vaccination Hesitancy, a new report released today by the Sabin-Aspen Vaccine Science and Policy Group, calls for an urgent, coordinated effort to strengthen vaccine acceptance and address the risk that vaccination hesitancy the reluctance or opposition to vaccination despite the availability of safe and effective vaccines poses to communities around the world.

The global call for a vaccine to end the COVID-19 pandemic highlights the value of vaccines for the health and economic stability of individuals and communities. While the world eagerly awaits the day when COVID-19 vaccines will be widely available, the threat of deadly vaccine-preventable outbreaks is at our doorstep. Just last year, the United States suffered its largest measles outbreak in 20 years, concentrated in communities with low immunization rates. Similar outbreaks have occurred around the world in communities susceptible to measles because of under vaccination.

Designed to maintain, restore and strengthen confidence in the value of vaccines, the report includes three big ideas that alone and together can contribute to reversing the trend. The report calls for:

Progress toward increasing immunization coverage has stalled in recent years, opening the door to outbreaks of measles and other vaccine-preventable diseases. This trend is often fueled by complacency and loss of confidence in the system that develops, produces, recommends and delivers vaccines. Hesitancy toward vaccination can be exacerbated by the spread of misinformation about the safety and efficacy of vaccines across the internet.

With misleading and conspiratorial vaccine theories proliferating online, it has become critical to effectively measure and understand the impact of vaccine misinformation, and to devise a strategy to enhance public trust in all vaccines. These actions are needed to protect overall health for the next generation and to ensure successful uptake of a COVID-19 vaccine when it is available.

The new report presents an in-depth analysis into the root causes of vaccine hesitancy, an exploration of the current landscape of misinformation and actionable steps to address these trends. The report is a product of the Sabin-Aspen Vaccine Science & Policy Group, a joint initiative of the Sabin Vaccine Institute (Sabin) and the Aspen Institute, made up of 24 global innovators and thought leaders with converged expertise across public health, medicine, philanthropy, venture capital, biotechnology, biology, ecology, ethics and journalism. Misinformation on social media and skepticism and distrust in government, industry and science are detailed in the five background papers that frame the report.

In order to shift the conversation and address the dangers of misinformation, we need to learn how people make decisions about vaccines, said Shirley M. Tilghman, president emerita of the university, professor of molecular biology and public affairs at Princeton University and Sabin-Aspen Group co-chair. This requires understanding the social processes that contribute to attitudes around vaccines and conducting effective education and outreach to activate awareness and support for immunization.

Developing strategies to counter vaccine hesitancy will require significant investment, as well as broader engagement with new disciplines and collaborators, especially within the social and behavioral sciences and with social media platforms, said Harvey V. Fineberg, M.D., Ph.D., president of the Gordon and Betty Moore Foundation and a Sabin-Aspen Group co-chair. Many of the tech companies are aware of and have begun to be responsive to vaccine misinformation; now its up to us to deepen this partnership to improve vaccine acceptance and protect the health of individuals and communities around the world.

Misinformation is emerging about COVID-19 vaccines, even as they are early in development, increasing the urgency to understand vaccine hesitancy and put forth actionable solutions, said Bruce Gellin, M.D., M.P.H., Sabins president of Global Immunization. We are proud to share this report, and grateful for our partnership with the Aspen Institute and the leaders who have brought their creativity and determination to this issue.

Vaccines face another obstacle their own success. Decades of diligent vaccination campaigns have established community immunity (or herd immunity), in which the percentage of a population immune to a disease is high enough to prevent its spread. As a result, the potentially deadly consequences of not vaccinating have become less apparent to the general public, leading to a rise in complacency.

Vaccine uptake is just as critical to understand and improve as vaccine access said Ruth Katz, executive director of the Aspen Institute Health, Medicine and Society (HMS) Program. If the factors that contribute to vaccine hesitancy complacency, convenience and confidence are not properly understood or addressed, the health and wellbeing of future generations will be at risk.

The Sabin-Aspen Vaccine Science & Policy Group is a partnership that brings together senior leaders across many disciplines to examine some of the most challenging vaccine-related issues and drive impactful change. This second meeting of the Sabin-Aspen Vaccine Science & Policy Group and its research and report were funded by the Bill & Melinda Gates Foundation.

Amid COVID-19 Vaccine Race, Sabin Vaccine Institute and the Aspen Institute Release Report on Vaccine Hesitancy; A Call to Improve Vaccine Acceptance...

June 2 (UPI) -- Army scientists are testing coronavirus vaccines developed by outside laboratories -- but also one created by the Army itself -- and are optimistic they'll have a vaccine ready by the end of the year.

Using a virus isolated from the blood of a Washington state man who was the virus' first U.S. death, Army researchers are testing vaccines in hundreds of mice, and researchers are also working to evaluate test vaccines produced by pharmaceutical companies under the White House's "Operation Warp Speed," which has a stated goal of producing a virus by the end of the year.

Human clinical trials could begin as soon as the end of the summer.

"We've done a lot of work that you'll hear about in the near future showing that all the [COVID-19-linked] viruses circulating in the world can be covered by a single vaccine," Kayvon Modjarrad, director of emerging infectious diseases at the Walter Reed Army Institute of Research, told reporters Tuesday.

Some reports suggest there are multiple coronavirus strains -- perhaps as many as eight -- circulating around the world, and that some may be more contagious than others, so the possibility of a vaccine that could handle multiple strains would be a significant development.

"There's no evidence currently that there are new strains," Modjarrad said Tuesday, but the Army's vaccine is being designed with a long-term approach to combating new strains of the novel coronavirus, so researchers could more easily fight any strains that arise.

There are still other unknowns researchers have to contend with -- including the possibility of re-infection and the wide variety of health outcomes for the infected.

It's also too early to tell exactly how long the vaccine's effects will last after patients receive it -- since researchers don't yet know how long it lasts from people who get infected naturally.

Ensuring access to the vaccine once it's been developed is also out of the Army's hands.

Instead it will be up to the Centers for Disease Control to execute a campaign to deploy the vaccine broadly, and the the Food and Drug Administration will also have a "very strong hand" in deciding who gets immunized, according to Nelson Michael, the director of the Center for Infectious Disease Research at the Walter Reed Army Institute of Research.

COVID-19 vaccine to be tested on 30 monkeys in NIV Pune, Forest Department gives its nod  |  Photo Credit: iStock Images

New Delhi: As the race towards developing and testing vaccines against the novel coronavirus infection intensifies, with India playing a major role in treatment and vaccine trials, ICMR'S National Institute of Virology, Pune, has been granted the use of 30 monkeys for vaccine trials, TOI reported.

30 monkeys of the female gender, in the age of three to four years, will be given to the institute to test the COVID-19 vaccine. The monkeys will reportedly be procured from the Vadgaon forest range in Pune.

Sources have, however, said that the institute will have to do the monkey catching itself, with the forest department only assisting them in the process.

Forest Minister Sanjay Rathod said, The vaccine will be tested on the monkeys and I have granted permission for it. He added, NIV will have to ensure their daily routine is not disrupted and the project cannot be used on a commercial basis. He also said that the permissions were granted on the condition that NIV will take good care of the animals.

The permissions were granted keeping in view that NIV was a government institution. More than 10 vaccines areunder trial in the country. Dr Harsh Vardhan last week said that around 4 vaccines are likely to enter the phase of clinical trials in the next 3 to 6 months.

A vaccine is one of the only ray of hopes against the novel coronavirus, SARS-CoV-2, the virus responsible for causing COVID-19. There is no specific cure, or vaccine available against the virus, as of now.

COVID-19 vaccine to be tested on 30 monkeys in NIV Pune, Forest Department gives its nod - Times Now

BILTHOVEN, Netherlands andPROVIDENCE, Rhode Island, June 2, 2020 /PRNewswire/ --Intravacc, one of the world's leading translational research and development vaccine institutes, with an extensive track record in developing viral and bacterial vaccines, and EpiVax, a biotechnology company based in Providence with expertise in developing vaccines and therapeutics, announce that they have entered into a collaboration agreement to further progress an novel vaccine against COVID-19, based on Intravacc's proprietary Outer Membrane Vesicles (OMV) technology platform.

For this joint research project, Intravacc will combine its safe and immunogenic OMV delivery platform with synthetically produced COVID-19 epitopes (protein allergens), designed and optimized by EpiVax using advanced immunoinformatics tools, in order to generate a safe and highly effective T-cell response against SARS-CoV-2 and related coronaviruses. Pre-clinical studies will start immediately so as to select the best candidate peptides for the vaccine. Intravacc will utilize its in-house pilot-scale facility for the GMP production of the OMV-peptide vaccine, for clinical (phase I) studies expecting to start in Q4 2020.

Annie De Groot, MD, CEO and CSO of EpiVax, said:

"We are thrilled to enter into a partnership with Intravacc using their very novel 'click-on' OMV technology and the highly immunogenic and safe SARS-CoV-2 multi-epitope-bearing peptides designed using the iVAX toolkit at EpiVax. We believe that the combination of technologies and the strength of our longstanding collaboration with Intravacc will lead to the development of an effective and safe vaccine that could rapidly benefit hundreds of millions of people around the globe."

Dr. Jan Groen, CEO of Intravacc, stated:

"A COVID-19 vaccine based on this approach is expected to be very safe and to reduce the morbidity and mortality rates associated with COVID-19. The vaccine is expected to lower the risk that individuals infected with SARS-CoV-2 will require hospitalization and/or intensive care. It also expected to induce long-term memory responses to prevent COVID-19 disease and infection from other beta-corona viruses. We expect that leveraging Intravacc's unique vaccine development expertise, broad-based network and successful track record in global technology transfer to vaccine manufacturers will bring success".

About Intravacc's OMV platform technology

For the development of vaccines against pathogens, Intravacc has designed and developed a platform based on outer membrane vesicles (OMVs) spherical particles with intrinsic adjuvating properties. Using genetic engineering, the OMVs can be decorated with immunogenic peptides that combine T- cell epitopes that will drive effective adaptive immunity. Heterologous OMV vaccines are a suitable alternative approach to protect against pathogens that require a high level of containment, that are difficult to cultivate, or that contain viral and/or parasitic proteins. The antigens of choice are attached to the 'empty' OMV carrier resulting in a more effective immune response.

Intravacc also has developed genetic tools to increase the yield of OMVs, to reduce toxicity, and to achieve the desired antigenic composition. Intravacc's OMV platform is fully scalable and allows for fast and efficient modification of antigen composition, either via genetic modification of the bacterial host or by associating antigens to stockpiled carrier OMVs.

About Intravacc

The Netherlands-based Intravacc is one of the world's leading institutes for translational vaccinology. As an established independent R&D organization with over 100 years' experience in the development and optimization of vaccines and vaccine technologies, Intravacc has transferred its technology all over the globe, including oral polio vaccines, measles vaccines, and DPT, Hib and influenza vaccines. Intravacc offers a wide range of expertise to independently develop vaccines from lead concept to clinical phase I/II studies for partners worldwide such as academia, public health organizations (WHO, BMGF), and biotech and pharmaceutical companies.

Intravacc also has its own proprietary vaccine platform. Intravacc has established state-of-the-art research and production (GMP) facilities. Its aim is to substantially reduce development risks and costs of new vaccines in order to contribute to global health and equity in access to vaccines worldwide.

When could a COVID-19 vaccine be ready?

Top health officials say the end of this year would be a best case scenario. But scientists have never created a vaccine so quickly, and theres no guarantee any under development will ultimately work.

Worldwide, testing recently started or is about to start for about a dozen potential vaccines. The most promising vaccine candidates are expected to move into larger tests this summer.

How quickly those studies can determine whether the vaccines are safe and effective depends in part on how widely the coronavirus is still spreading. The studies will need to enroll 20,000 people or more for each vaccine candidate, with half of them getting the real vaccine and the rest getting a dummy shot. Then its a matter of waiting to see how many in each group become infected with the virus.

Answers will come faster if volunteers are recruited in places where outbreaks are worsening, a trend that can be hard to predict.

One way to speed up distribution is to start manufacturing doses before test results are in. But its a gamble that could mean throwing away tons of vaccines that fail.
