Australian researchers have made an important discovery in the race to find a COVID-19 vaccine – SBS News

March 17, 2020

The immune responses from one of Australia's first coronavirus patients have been mapped, which researchers say is the first step towards finding a vaccine.

Researchers at Melbourne's Peter Doherty Institute for Infection tested at four different points in time the blood samples of an otherwise healthy woman who was diagnosed with coronavirus.

They were able to record how her immune system responded to COVID-19, and how it was able to overcome the virus.

Laboratory Head Professor Katherine Kedzierska told SBS News the patient's immune response was similar to that of a patient with influenza.

"When we were analysing the immune responses, we saw really textbook images of several different immune cell types emerging in the patient's blood," she said.

"Even though COVID-19 is caused by a new virus, in an otherwise healthy person, we can generate a robust immune response across different cell types."

"This is an important step forward in understanding what drives recovery."

"Now we can do research on understanding what's lacking, or what's different in patients that have fatal disease outcomes."

Scientists from The Peter Doherty Institute for Infection and Immunity were able to succesfully grow a version of the Coronavirus in January.

Research fellow Oanh Nguyen said it is the first time broad immune responses to COVID-19 have been reported.

"Three days after the patient was admitted, we saw large populations of several immune cells, which are often a tell-tale sign of recovery during seasonal influenza infection."

"We predicted that the patient would recover in three days, which is what happened."

In January, Doherty Institute researchers became the first outside China to successfully grow the Wuhan Coronavirus from a patient sample.

Now by dissecting the immune response, scientists are a step closer to finding an effective Coronavirus vaccine.

But ProfessorKedzierska said there are "many more questions" scientists are yet to answer.

"We've shown that this patient expressed antibodies, which are obviously important for the vaccine development," she said.

"We still need to understand the nature of those antibodies, whether they can neutralise the virus or not."

And it's too early to tell if patients who've had the Coronavirus are immune from future infections.

"We need to understand whether those immune responses can proceed into immunological memory[and whether] we still got those cells that can protect us against reinfection...with the same virus."

The findings were published on Tuesday in a medical journal called Nature Medicine.

Coronavirus symptoms can range from mild illness to pneumonia, according to the Federal Government's website, and can include a fever, coughing, sore throat, fatigue and shortness of breath.

There are now more than 375 coronavirus cases across Australia.

As of Tuesday afternoon, only people who have recently travelled from overseas or have been in contact with a confirmed COVID-19 case and experienced symptoms within 14 days are advised to be tested.

If you believe you may have contracted the virus, call your doctor, dont visit, or contact the national Coronavirus Health Information Hotline on 1800 020 080.

If you are struggling to breathe or experiencing a medical emergency, call 000.

10 Positive Updates on the COVID-19 Outbreaks From Around the World – Good News Network

March 17, 2020

If it seems that your news feed has been flooded with nerve-wracking updates on the COVID-19 outbreaks, have no fearthere are also plenty of positive updates on the pandemic as well.

So without any further ado, here is a list of 10 hopeful headlines on the coronavirus response from around the world.

Scientists at the Kaiser Permanente Washington Research Institute in Seattle delivered the first rounds of a potential coronavirus vaccine to several dozen optimistic volunteers earlier this week.

43-year-old vaccine recipient Jennifer Haller, who is also a mother to two teenagers, was all smiles after she told AP reporters she was feeling great as she was leaving the clinic. This is an amazing opportunity for me to do something, she added.

Amidst national shortages of hand sanitizers, alcohol distilleries in Atlanta, Portland, rural Georgia, and North Carolina have begun using their facilities to make their own sanitation products.

Since the World Health Organization (WHO) says that cleaning your hands with an alcohol-based rub can help to kill viruses on your hands, many of the distilleries say they hope to continue producing their bootleg sanitizers until the virus has been properly contained.

Satellite readings of air pollution levels over China and Italy show that the regions hit hardest by the COVID-19 have also caused air pollution levels to decline dramatically.

Some reports estimate that Chinas quarantine has saved more than 100 million metric tons of carbon dioxide emissions from entering the atmospherewhich is about the equivalent of what Chile produces in a year.

Not only have similar effects been reported across Italy, the canals and waterways of Venice are reportedly cleaner than ever with the waters shining crystal clear in the absence of diesel-powered boats and gondoliers.

The vaccine developers in Seattle arent the only ones working on potential treatments and cures for the diseasean immunologist from Johns Hopkins University is reviving a century-old blood-derived treatment for use in the United States in hopes of slowing the spread of the disease.

The technique uses antibodies from the blood plasma or serum of people who have recovered from COVID-19 infection to boost the immunity of newly-infected patients and those at risk of contracting the disease.

According to Reuters, South Korea recorded more COVID-19 recovery cases on March 6th than new infections for the first time since the nation experienced the largest Asian outbreak outside of China.

Since the novel coronavirus outbreak was first reported in South Korea back in January, the nation reached a peak of 909 new infections on February 29th.

Now, however, Reuters reports that the declining rate of infection has continued to fall with less than 100 new cases reported for several days in a row.

Crowds of medical staffers and discharged patients were filmed celebrating the closure of all 14 temporary hospitals that opened in Wuhan to treat COVID-19 patients during the worst of the outbreak.

Authorities told the South China Morning Post this week that the virus had finally passed its peak as the nations mainland experienced only 11 new cases on March 13th, most of which were from international travelers.

As the outbreak is finally brought under control, parks and tourist attractions are slowly beginning to reopen to the public under careful moderation.

At the University of Queensland Centre for Clinical Research, scientists have found that two different medicationsboth of which are registered and available in Australiahave completely wiped out traces of the disease in test tubes.

Not only that, the drugs were given to some of the nations first COVID-19 patients, which resulted in disappearance of the virus and complete recovery from the infection, researchers told News.com.au.

The university is now looking to conduct a nationwide trial with the drugs to evaluate the efficacy and tolerance of each drug administered separately and together.

As restaurants across Canada and the United States are forced to temporarily shut down amidst COVID-19 outbreaks, Uber Eats has announced that they will be waiving delivery fees for independent restaurants.

We know the success of every restaurant depends on customer demand, the company said in a statement. Thats why were working urgently to drive orders towards independent restaurants on Eats, to help make up for the significant slowdown of in-restaurant dining.

As more customers are choosing to stay indoors, weve waived the Delivery Fee for the more than 100,000 independent restaurants across US and Canada on Uber Eats. We will also launch daily dedicated, targeted marketing campaignsboth in-app and via emailto promote delivery from local restaurants, especially those that are new to the app.

Scientists from Canada and the Netherlands have also made medical breakthroughs of their own. In Toronto, a team of researchers managed to isolate the agent responsible for the ongoing outbreak of COVID-19, which will help researchers around the world develop better diagnostic testing, treatments, and vaccines.

Researchers from these world-class institutions came together in a grassroots way to successfully isolate the virus in just a few short weeks, said Dr. Rob Kozak, clinical microbiologist at Sunnybrook University. It demonstrates the amazing things that can happen when we collaborate.

Meanwhile, Dutch researchers have submitted a scientific paper for publishing on how they have identified an anti-body for the virusand it could be a world-first.

Dollar General has announced that they will be devoting their opening hour of shopping time to elderly customers. Athletes and sports teams are pledging to pay the wages of arena employees during the shutdown. Utility companies, landlords, automakers, and internet providers are waiving a number of late fees and payments to ease the financial burden of the shutdown. School districts across the country are still opening their doors to serve meals to kids and families.

All in all, the pandemic situation may seem grim, but these are just a few examples of how businesses and individuals are still looking out for each other during times of trouble.

Authorities warn of scam callers seeking sensitive information to reserve a vaccine for COVID-19 – FOX 13 Tampa Bay

March 17, 2020

LOS ANGELES - As fears over the COVID-19 pandemic grow following mass closures across the United States, concerns of scammers attempting to take advantage of the chaotic situation are circulating as confusion and panic spread.

RELATED:CoronavirusNOW.com, FOX launches national hub for COVID-19 news and updates.

The Lucas County Sheriffs Office in Ohio issued a warning to its followers to be on the lookout for con artists claiming to be with the Centers for Disease Control and Prevention attempting to lure people into reserving a vaccine to prevent COVID-19.

Scammers have been calling people requesting credit card and social security numbers in exchange for reserving a vaccine that currently does not exist, according to the sheriffs office.

Anyone receiving such a call should not under any circumstances give the caller any personal information or money," the Lucas County Sheriffs Office wrote on their Facebook page.

U.S. researchers gave the first shots in a clinical trial of an experimental coronavirus vaccine Monday. But even if the research goes well, a vaccine would not be available for widespread use for 12 to 18 months, according to Dr. Anthony Fauci of the U.S. National Institutes of Health.

On March 15, the National Security Council tweeted regarding a concern over fake text message rumors circulating throughout the public about a national quarantine.

On March 6, the Cybersecurity and Infrastructure Security Agency (CISA) issued an alert reminding individuals to be wary of possible scams related to the pandemic that has completely upended the social and economic fabric of the world.

Cyber actors may send emails with malicious attachments or links to fraudulent websites to trick victims into revealing sensitive information or donating to fraudulent charities or causes, the organization said. Exercise caution in handling any email with a COVID-19-related subject line, attachment, or hyperlink, and be wary of social media pleas, texts, or calls related to COVID-19.

Carolina Sanchez breaks down what you need to know about this health affliction.

CISA warns against giving away sensitive information over email and advises people to be wary of clicking on any link attachments sent via email.

RELATED:Coronavirus cancellations: These major events, concerts called off amid COVID-19 outbreak

CISA said that federal, state, local, tribal and territorial COVID-19 information sites are the best resources for up-to-date information on the pandemic.

The Secret Service said scammers send emails under the guise of a medical official with important information about coronavirus. When the victim lets their guard down and opens an attached file, their computer becomes infected with malware.

The scammer could access the victims passwords and possibly even their financial information.

In non-delivery schemes, victims are told about an in-demand medical supply that can prevent coronavirus. Once they pay for it, the victim never hears from the seller again or receives a product, the agency said.

Avoid opening attachments and clicking on links within emails from senders you do not recognize, the Secret Service said. These attachments can contain malicious content, such as ransomware, that can infect your device and steal your information.

COVID-19 Vaccine Still on Phase 1 and Might Take 18 Months From Now to Create Says Global Health Official – Tech Times

March 17, 2020

Coronavirus or COVID-19 cureis still under a long process for now. This is what Global Health Official revealed on Bloomberg in an exclusive interview when he was asked about the real status of theviruscure in the world. Clearly, the official said that there was already a potential cure for the viral disease, but it's now only on Phase 1, which means it still has a long way to go before officially announcing it as the primary COVID-19 cure. What to do now?

(Photo : VIDO-InterVac on Reuters)COVID-19 Cure Still on Phase 1 and Might Take 18 Months From Now to Create Says Global Health Official

Bloomberg recentlyexclusively interviewedArnaud Bernaert, a representative from the World Economic Forum Head of Global Health and Healthcare, and asked him on his personal views regarding the formulation of COVID-19 cure. Bernaert admitted on air that the cure might take a while to create before officially distributing it around the world and claimed it as the cure for the novel virus.

As estimated by Bernaert, the virus cure might take over a year or exactly 18 months--since the medicine is still on Phase 1-- before people will be cured by the formulation.

"You need to understand that Phase 1 means that we only verify that the vaccine is not toxic to humans. It's a state that is very early on the discovery process. You have to remain and demonstrate efficacy and, most importantly, and the vaccine can be manufactured at the scale which is an issue in the context of existing filling capacity for vaccines globally," said him. "I would say it's promising, but it's still a long way, and I tend to agree with clinical experts on that 18 months is a reasonable time frame of seeing a vaccine."

The Biomedical Advanced, Research and Development Authority, wassaidto be working with pharmaceutical companies such as Sanofi and Johnson & Johnson on creating potential vaccines against the disease. They were supposed to be the company that already reached phase 1 of getting the cure.

National Institute of Allergy and Infectious Diseases Director Anthony S. Fauci already said that finding the cure for the Coronavirus is their main priority for today and having the phase 1 of the clinical trial of the potential vaccine will be a huge help for their discovery.

"Finding a safe and effective vaccine to prevent infection with SARS-CoV-2 is an urgent public health priority," said him in a statement. "This Phase 1 study, launched in record speed, is an important first step toward achieving that goal."

As of now, authorities around the world are still advising all citizens to be aware of proper hygiene on their residences to protect themselves from getting the virus.

SEATTLE (AP) U.S. researchers gave the first shots in a first test of an experimental coronavirus vaccine Monday, leading off a worldwide hunt for protection even as the pandemic surges.

With careful jabs in the arms of four healthy volunteers, scientists at the Kaiser Permanente Washington Research Institute in Seattle began an anxiously awaited first-stage study of a potential COVID-19 vaccine developed in record time after the new virus exploded out of China and fanned out across the globe.

Were team coronavirus now, Kaiser Permanente study leader Dr. Lisa Jackson said on the eve of the experiment. Everyone wants to do what they can in this emergency.

The Associated Press observed as the studys first participant, an operations manager at a small tech company, received the injection in an exam room.

We all feel so helpless. This is an amazing opportunity for me to do something, Jennifer Haller, 43, of Seattle said before getting vaccinated. Her two teenagers think it's cool that she's taking part in the study.

After the injection, she left the exam room with a big smile: I'm feeling great."

Three others were next in line for a test that will ultimately give 45 volunteers two doses, a month apart.

Neal Browning, 46, of Bothell, Washington, is a Microsoft network engineer who says his young daughters are proud he volunteered.

Every parent wants their children to look up to them, he said. But hes told them not to brag to their friends. Its other people, too. Its not just Dad out there.

Mondays milestone marked just the beginning of a series of studies in people needed to prove whether the shots are safe and could work. Even if the research goes well, a vaccine would not be available for widespread use for 12 to 18 months, said Dr. Anthony Fauci of the U.S. National Institutes of Health.

Still, finding a vaccine is an urgent public health priority, Fauci said in a statement Monday. The new study is an important first step toward achieving that goal.

This vaccine candidate, code-named mRNA-1273, was developed by the NIH and Massachusetts-based biotechnology company Moderna Inc. Theres no chance participants could get infected because the shots do not contain the coronavirus itself.

Its not the only potential vaccine in the pipeline. Dozens of research groups around the world are racing to create a vaccine against COVID-19. Another candidate, made by Inovio Pharmaceuticals, is expected to begin its own safety study next month in the U.S., China and South Korea.

The Seattle experiment got underway days after the World Health Organization declared the new virus outbreak a pandemic because of its rapid global spread, which has infected more than 169,000 people and killed more than 6,500.

COVID-19 has upended the worlds social and economic fabric since China first identified the virus in January, with broad regions shuttering schools and businesses, restricting travel, canceling entertainment and sporting events, and encouraging people to stay away from each other.

Starting what scientists call a first-in-humans study is a momentous occasion for scientists, but Jackson described her teams mood as subdued. Theyve been working around-the-clock readying the research in a part of the U.S. struck early and hard by the virus.

Still, going from not even knowing that this virus was out there ... to have any vaccine in testing in about two months is unprecedented, Jackson told the AP.

Some of the studys carefully chosen healthy volunteers, ages 18 to 55, will get higher dosages than others to test how strong the inoculations should be. Scientists will check for any side effects and draw blood samples to test if the vaccine is revving up the immune system, looking for encouraging clues like the NIH earlier found in vaccinated mice.

We dont know whether this vaccine will induce an immune response or whether it will be safe. Thats why were doing a trial, Jackson stressed. Its not at the stage where it would be possible or prudent to give it to the general population.

Most of the vaccine research under way globally targets a protein aptly named spike that studs the surface of the new coronavirus and lets it invade human cells. Block that protein and people cannot get infected.

Researchers at the NIH copied the section of the virus genetic code that contains the instructions for cells to create the spike protein. Moderna encased that messenger RNA into a vaccine.

The idea: The body will become a mini-factory, producing some harmless spike protein. When the immune system spots the foreign protein, it will make antibodies to attack and be primed to react quickly if the person later encounters the real virus.

Thats a much faster way of producing a vaccine than the traditional approach of growing virus in the lab and preparing shots from either killed or weakened versions of it.

But because vaccines are given to millions of healthy people, it takes time to test them in large enough numbers to spot an uncommon side effect, cautioned Dr. Nelson Michael of the Walter Reed Army Institute of Research, which is developing a different vaccine candidate.

The science can go very quickly but, first, do no harm, right? he told reporters last week.

The Seattle research institute is part of a government network that tests all kinds of vaccines and was chosen for the coronavirus vaccine study before COVID-19 began spreading widely in Washington state.

Kaiser Permanente screened dozens of people, looking for those who have no chronic health problems and are not currently sick. Researchers are not checking whether would-be volunteers already had a mild case of COVID-19 before deciding if they are eligible.

If some did, scientists will be able to tell by the number of antibodies in their pre-vaccination blood test and account for that, Jackson said. Participants will be paid $100 for each clinic visit in the study.

--------

WASHINGTON (AP) A clinical trial evaluating a vaccine designed to protect against the new coronavirus will begin Monday, according to a government official.

The first participant in the trial will receive the experimental vaccine on Monday, the official said, speaking on the condition of anonymity because the trial has not been publicly announced yet. The National Institutes of Health is funding the trial, which is taking place at the Kaiser Permanente Washington Health Research Institute in Seattle, the official said.

Public health officials say it will take a year to 18 months to fully validate any potential vaccine.

Testing will begin with 45 young, healthy volunteers with different doses of shots co-developed by NIH and Moderna Inc. Theres no chance participants could get infected from the shots, because they dont contain the virus itself. The goal is purely to check that the vaccines show no worrisome side effects, setting the stage for larger tests.

Dozens of research groups around the world are racing to create a vaccine as COVID-19 cases continue to grow. Importantly, theyre pursuing different types of vaccines shots developed from new technologies that not only are faster to produce than traditional inoculations but might prove more potent. Some researchers even aim for temporary vaccines, such as shots that might guard peoples health a month or two at a time while longer-lasting protection is developed.

For most people, the new coronavirus causes only mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia. The worldwide outbreak has sickened more than 156,000 people and left more than 5,800 dead. The death toll in the United States is more than 50, while infections neared 3,000 across 49 states and the District of Columbia.

The vast majority of people recover. According to the World Health Organization, people with mild illness recover in about two weeks, while those with more severe illness may take three weeks to six weeks to recover.

Commentary: Is the UK’s herd immunity strategy to combat COVID-19 worth pursuing? – CNA

March 17, 2020

Commentary Commentary

Achieving herd immunity to COVID-19 in the UK could result in the deaths of more than 1 million people with a further 8 million severe infections requiring critical care, says an observer.

Bookmark

CANTERBURY: The UK government recently enacted its second phase of response to the COVID-19 pandemic: Delay.

According to ITV journalist Robert Peston, the governments strategy to minimise the impact of COVID-19 is to allow the virus to pass through the entire population so that people acquire herd immunity, but at a much delayed speed. This is so that those who suffer the most acute symptoms are able to receive the necessary medical support without overwhelming the National Health Service (NHS) with cases.

At face value, this seems like a sound strategy, but what exactly is herd immunity and can it be used to combat COVID-19?

HOW HERD IMMUNITY WORKS

Our bodies fight infectious diseases through the actions of our immune systems. When we recover, we often retain an immunological memory of the disease that enables us to fight off that same disease in the future.

This is how vaccines work, creating this immune memory without requiring getting sick with the disease.

If you have a new disease, such as COVID-19, that we dont have a vaccine for and no one in the country has ever been infected with, the disease will spread through the population.

But if enough people develop an immune memory, then the disease will stop spreading, even if some of the population is not immune. This is herd immunity, and it is a very effective way to protect the whole of a population against an infectious disease.

But herd immunity is typically only viewed as a preventive strategy in vaccination programmes. If we dont have a vaccine as we dont for COVID-19 achieving herd immunity would require a significant proportion of the population to be infected and recover from COVID-19.

So what would this mean for the spread of the disease in the UK?

The percentage of the population that needs to be immune to enable herd immunity depends on how transmissible a disease is. This is measured by the term R0, which is how many new infections each case will generate.

For COVID-19, the R0 is estimated to be 3.28, though studies are still ongoing and this number will probably change. This means that for herd immunity, about 70 per cent of the UK population would need to be immune to COVID-19.

Achieving herd immunity would require well over 47 million people to be infected in the UK. Current estimates are that COVID-19 has a 2.3 per cent case-fatality rate and a 19 per cent rate of severe disease.

This means that achieving herd immunity to COVID-19 in the UK could result in the deaths of more a million people with a further 8 million severe infections requiring critical care.

DELAY AS A PUBLIC HEALTH STRATEGY

However, it is not clear how much of this discussion of herd immunity reportedly proposed by David Halpern, chief executive of the Behavioural Insights Team, and later blogged about by Robert Peston shapesgovernment policy.

Also, the concept as discussed is not simply to let the disease run its course through the population, but to slow its spread and protect those most vulnerable from severe disease.

Slowing the spread of COVID-19 is a promising strategy, especially when combined with enhanced measures to protect the elderly and those with underlying health conditions

By slowing the spread of the disease, the NHS might have more time to prepare, we might be able to develop treatments or vaccines and we will be closer to the summer when we have lower incidences of other diseases that burden the NHS, such as the flu.

A delay strategy when combined with surveillance and containment, as recommended by the WHO, could be effective in combating the spread of COVID-19.

Yet if the UKslows the spread of the virus but relieson herd immunity to protect the most vulnerable people, itwould still need 47 million people to be infected.

Even if the UKmanages to protect the most vulnerable people (though no discussion is provided on how this will be done or for how long) the fatality rate for the otherwise healthy portion of the population may still be 0.5 per cent or higher. This means that even in this unlikely best case scenario we would still be looking at more than 236,000 deaths.

We can and we must do better than that. China is rapidly controlling the spread of COVID-19 without requiring herd immunity (only 0.0056 per cent of its population has been infected).

Waiting for herd immunity to COVID-19 to develop in the UK by letting the virus pass through the community is not a good public health strategy.

British pharmaceutical giant GSK is working with two outside organizations for preclinical studies on Covid-19 vaccines using its pandemic vaccine adjuvant platform, a technology used to develop HPV and flu vaccines in the past.

GSK has provided the technology to University of Queensland program funded by the Coalition for Epidemic Preparedness Innovations (CEPI), an international organization based in Oslo, Clover Biopharmaceuticals, a Chinese biotech company thats making a vaccine called Covid-19 S-Trimer.

In collaboration with the Biomedical Advanced Research and Development Authority (BARDA), a division under the Department of Health and Human Services (HHS), Johnson & Johnson is exploring candidates for both vaccines and antiviral drugs.

Similar to GSK, the American pharma giant is using its vaccine platform technology, which was used for the developing an experimental Ebola vaccine in 2009.

We are also in discussions with other partners, that if we have a vaccine candidate with potential, we aim to make it accessible to China and other parts of the world, Paul Stoffels, Johnson & Johnsons chief scientific officer, said in a statement last month.

The company aims to start a Phase 1 clinical trial by the end of 2020, Stoffel said last week.

Inovio recently completed the preclinical testing of a DNA-based vaccine called INO-4800. And clinical trials are expected to begin in April with patients in the U.S., as well as China and South Korea.

The company expects to have first trial results in the fall and have one million vaccines doses ready by the end of the year.

Biotech startup Moderna is developing an RNA-based vaccine candidate called mRNA-1273 through a program funded by CEPI. Last month, the company shipped a batch of the vaccine to the National Institute of Allergy and Infectious Diseases (NIAID), a division under the National Institutes of Health. Clinical trials are expected to start next week and conclude on June 1 next year.

A frontrunner among existing Covid-19 therapy projects, Gileads antiviral drug, Remdesivir, is currently used in a phase 3 trial on over 1,000 patients around the world.

The experimental drug was first tested on Covid-19 patients in Wuhan, China, the epicenter of the coronavirus outbreak. Last month, the NIAID allowed the company to expand phase 3 trials to other countries hit by the virus.

Trial results from China can be expected as soon as April.
