Michael Irvin has contracted the coronavirus.
At least, at some point he did.
During an appearance on the Rich Eisen Show, the Hall of Fame Cowboys receiver revealed his experience dealing with COVID-19 earlier this summer.
Irvin said he tested negative for coronavirus twice, but an antibody test revealed he had contracted the disease.

To get the US pandemic under control, a growing number of health and medical experts are making a clarion call for an additional testing approach to Covid-19.
What we need, they argue, are at-home rapid tests that look for antigens, proteins the live virus makes. These kits would allow anyone to test themselves for the coronavirus any time (and anywhere) for between $1 and $5, and get results in about 15 minutes. No doctors, labs, expensive machines, or special chemicals required.
I see these [antigen] tests as a solution thats literally sitting in front of us, says Michael Mina, an epidemiologist at the Harvard T.H. Chan School of Public Health, who has led an effort to get these rapid tests authorized by the Food and Drug Administration. We could be getting massive outbreaks down to nothing. ... Its a no-brainer to me.
Back in April, Deborah Birx, the White House coronavirus response coordinator, actually called for just this sort of solution in an interview on Meet the Press. We have to have a breakthrough innovation in testing, she said. We have to be able to detect antigen.
Several small companies have been developing these simple tests, and the conglomerate 3M is working with MIT on another one. (The new BinaxNOW test from Abbott, authorized August 26, is different it requires a health professional to administer it, and the patient must have symptoms to get a prescription.)
And some of these at-home tests are ready to go. But they have been sitting on the shelf, unused, for months. Why?
The holdup is that rapid, over-the-counter antigen tests are not nearly as sensitive to the coronavirus as the molecular PCR (polymerase chain reaction) tests currently used for most Covid-19 testing. In fact, by PCR standards, some at-home antigen tests might catch only half or a third of people who test positive on a PCR test.
But thats because theyre looking for different things in different ways. A PCR test, designed to diagnose an individual with infection, can catch very low levels of viral material before or after a person spreads the virus. An over-the-counter antigen test, meanwhile, relies on high levels of the virus to be able to detect it. These high levels, though, also happen to coincide with when a person is most likely to transmit the virus to others.
The antigen test is maximally sensitive at the same time that you are maximally infectious, says David Paltiel, a professor of public health and health policy at the Yale School of Public Health. The antigen test is picking up the infections I want. Because I dont care about infections, I care about infectiousness.
Since at-home antigen tests would be fast and cheap, they could allow people to test themselves regularly. Currently, PCR testing is relatively expensive (about $100) and often experiences processing delays that hamstring efforts to stop transmission.
PCR tests sensitivity, however, is the current benchmark by which the FDA judges new tests for emergency authorization.
This pre-pandemic framework, Mina and others argue, is a problem as we look for the most effective tools to fight the coronavirus right now. So they are calling for a new way to evaluate these tests, one based in public health terms rather than individual diagnostic ones in other words, widely accessible tests that are well tuned to find those who are most likely to spread the virus.
Lets take a look at how and why this potential solution has gotten sidelined in the pandemic battle and what might be done to get these tests off companies shelves and out to the public.
To understand the stalemate around antigen tests, its helpful to first understand what they are, how they differ from classic PCR tests, and the trajectory of coronavirus infections.
First: An antigen test looks for a particular protein from a live virus. (Not to be confused with an antibody test, which finds immune cells your body has made after mounting a defense against the virus.) These tests need a lot of viral material to generate a positive result.
Second: A PCR test looks for the viruss genetic material its RNA making copies of itself until it reaches a detectable level. As a result, it has a fairly low (although not perfect) false-negative rate, or the proportion of time it would tell someone who has the virus that they dont.
Finally: One of this new coronaviruss superpowers is its ability to spread from people before they start to experience symptoms. In fact, people tend to carry the most live virus the day or so before they begin feeling sick, and the amount tends to quickly trail off in the several days after symptom onset.
So proponents of at-home antigen testing say that PCR tests, while useful in determining whether an individual is infected with Covid-19, are actually a poor tool in finding people who are most likely to spread the virus. Thats because PCR tests are so sensitive, they are excellent at picking up traces of the virus even after someone has beat it back and is no longer infectious.
Thomas Tsai, a health policy expert at the Harvard T.H. Chan School of Public health, compares the two types of testing this way: PCR tests are reactive tests, usually used for people who either have symptoms, a close contact with the virus, or other reason to think they are likely to have caught it. Rapid, widespread antigen tests are proactive tests, designed to find cases before they spread the virus more widely.
And as the Center for Evidence-Based Medicine noted earlier this month, while an infectious stage may last a week or so because inactivated RNA degrades slowly over time, it may still be detected many weeks after infectiousness has dissipated.
To look a little bit deeper at how this works, an August 7 preprint report which hasnt been peer reviewed proposes that people with 10,000 copies of the virus detected in their airways are unlikely to spread the virus to someone else, even with sustained contact (according to their models, it would happen about 0.002 percent of the time). Once that viral load climbs to 10 million copies (which happens quickly, potentially in about a day), they have about a 40 percent chance of transmitting it to a close contact and about 80 percent chance at 100 million viral copies (its worth noting that when they first reach this level they still might not have any symptoms).
By the time someone has had Covid-19 symptoms for several days (which might currently be about the time they receive results from a PCR test), however, the amount of virus in their system has likely waned to the point of actually being less transmissible. As the authors of the study note, transmission after the first week of infection is quite rare.
At that point, says Mina, its more likely that they just have residual [virus] RNA hanging about. So although many of these people would get a positive PCR test and a negative at-home antigen test they are much less likely to transmit the virus than someone who feels fine now but will develop symptoms in a day or two.
The PCR is being fooled all the time, Paltiel says. The PCR is just picking up strands of viral junk. If your goal is to slow an outbreak, he notes, this sort of data is not actually that useful. Outbreak control is all about figuring out whos actually spreading this stuff.
This could also help explain why so many people continue to get positive PCR test results weeks after getting over most of their symptoms. One small JAMA study, for example, found that one in six former Covid-19 patients with no symptoms tested positive for the virus via PCR test four to 24 days after being discharged from the hospital. As an author of a commentary about that paper noted about these long-tail positive test results, the clinical significance and infectivity are minimal. These PCR tests likely are responding to noninfective RNA fragments and do not represent detection of viable virus.
Antigen tests, however, need a much higher level of the virus to register a positive result because they dont rely on multiplying their target.
This, experts argue, make them well matched for finding people with Covid-19 at precisely their most infectious points rather than potentially long after symptoms have arrived and infectiousness has faded, as is more likely now with the long delays in PCR results and contact tracing. As Paltiel describes it, the concept is pretty simple: The more viruses around your airway, the more likely you are to be a risk to others.
According to an analysis from the June preprint (on which Mina was a co-author), this crucial time period is precisely where the antigen test is most sensitive: detecting viral load at around 10,000 copies, which is just before someones infectiousness skyrockets. PCR tests, on the other hand, can pick up about 1,000 copies of the virus, which gives them about a days head start at finding the virus. Although with a lag of more than a day in returning results, that benefit is lost.
To put it in other terms, these tests could be superspreading detectors, Mina says, locating many of those who would otherwise go on to unknowingly infect many other people before they know they have the virus.
Their whole goal is to capture the 90 percent of people who might be transmitting the virus, Mina says. So if they were to be evaluated in this population those with high levels of the virus he says, the sensitivity for these tests would soar from 30 or 50 percent (as measured against PCR) up to 95 percent. (They also have very low false-positive rates, in which they would tell someone they had the virus when they actually didnt.)
Another selling point to antigen tests, proponents argue, is that they would give people their results much faster than PCR tests. Since delays of more than a day or so in getting PCR results back make containment and tracing much less effective, being able to have results back in 15 minutes or so would be a vast improvement.
Because these tests would be fast and affordable, people could also test frequently, which could help overcome worry about the tests being less sensitive than PCR especially in the very small window early in an infection when a PCR test might catch the virus but an antigen test wouldnt.
And such frequent testing would be far superior to the still relatively rare PCR testing that were currently doing, Paltiel says. Of all the variables that we control, the frequency of screening is the most important, he says. Even if the antigen-based test only caught half of all cases (regardless of infectiousness level), he says, if its between a test that is missing 50 percent [but rapid and easy] and a test that is getting everyone that is so expensive or so cumbersome or has such a long turnaround time that it takes a week, Ill take whats behind door No. 1.
In the June preprint study, the researchers found the sensitivity of a test made little difference in the rate at which it could bring viral transmission down. For example, running either of these tests, PCR or at-home antigen testing, on a population weekly could lower the spread of the virus by about 60 percent, they posit.
So, Mina suggests, we shouldnt just be asking what level of sensitivity a test has, but rather, what its sensitive to. PCR tests are great at finding traces of the coronavirus but, he says, its going to have a 0 percent sensitivity to detect elephants. And if what we want is to start finding elephants or people who are most infectious we should look for new testing options, he argues.
One of the FDAs essential responsibilities is to make sure dangerous medications, ineffective vaccines, or misleading diagnostic tests dont make it to US consumers. So it applies rigorous standards to make sure new products are reliable before they are allowed on the market.
And the FDA has applied this same rubric when it has evaluated new tests for the coronavirus this year.
Tests are still being considered first and foremost as diagnostic tools, Mina says. This is evident in how the FDA has required antigen tests to perform at PCR-levels in detecting traces of the virus in peoples systems, he notes. For example, a new test might need to detect the virus in 80 or 90 percent of emergency room patients whove received a positive PCR test.
So when you compare the numbers and see a test that catches half or a third of the positive cases a PCR test does, it makes sense for the FDA to worry about a huge number of Covid-19-positive people thinking they are negative.
And Mina says he gets that. If Im a doctor, which I am, and I have a patient in front of me, I would want the absolute best and most sensitive molecular test to make sure I dont miss something, he says.
But he is also an epidemiologist. For public health, its totally different. It requires a really different type of thinking. One that targets minimizing spread of the virus among people.
Unfortunately, the FDA just doesnt have that, he says. They dont even have a lens with which to think about it.
And so, he says, theyre still evaluating at-home antigen tests as individual medical diagnostic tools rather than as a virus control tool at the population level.
The FDA has already authorized four antigen-based tests, including ones from Quidel (in May), BD Veritor (in July), LuminaDX (in August), and the new one from Abbott. To meet the FDAs current sensitivity standards, however, the first three of these use proprietary machines to read results. (Some of these machines are now being allocated by the Centers for Medicare & Medicaid Services to nursing homes around the country.)
But an over-the-counter antigen test, the sort that Mina and others are advocating for, simply cant be authorized under the current standards.
This gets at the essential tension between the FDAs individual-based medical diagnostic framework and the broader public health needs of the pandemic. And, says Tsai, We really need to shift gears.
Beyond the sensitivity question, the FDA and others also have hesitations about these sorts of tests being done outside of the health care setting.
Current Covid-19 tests require a health care professional to order them and provide the results, allowing for them to give patients medical advice. If people are taking these tests on their own at home or before entering a business, a nurse wont be on hand, for example, to advise them to isolate if necessary or take other steps to prevent spread.
Due to the lack of healthcare professional supervision, FDA believes it is important for over-the-counter non-lab diagnostic tests to have a low rate of false negative results, Emma Spaulding, a spokesperson for the FDA wrote to Vox in an email. For example, an individual with a false negative result from an OTC diagnostic test may be less likely to quarantine despite symptoms, putting others in the community at risk,
This is one reason they are recommending such tests catch 90 percent of the PCR-positive cases, she says. They would lower this to 80 percent if the tests required a prescription and were done under the supervision of a health care worker (such as via telemedicine).
Others worry about individual compliance. Rebecca Lee Smith, an epidemiologist at the University of Illinois, notes that this sort of testing would probably be most readily adopted by people who are already putting in the most effort to avoid catching and spreading Covid-19, such as those regularly wearing masks and practicing physical distancing.
But the people who arent concerned about the virus may not choose to do at-home testing theyre also the people who are not taking the precautions. So the same people we would absolutely want to be checking for the virus, then, would be the people less likely to do it at home.
She also has concerns about at-home tests being used to clear people for work, school, or other activities. If someone needed to produce a negative test result, they could theoretically get someone else to take the test for them but still gain entry to, say, their college classes for the day. That was a point of discussion at her university, where they eventually opted for supervised (rather than collected-at-home) saliva-based PCR testing. We decided that it was more important that we know, for sure, that the person who checked in for testing is the person giving the sample, she says.
Administering these tests out in the community as a way to enter a workplace or a restaurant, for example, could also help alleviate this issue as well as the concern about those with higher chances of contracting the virus not taking the test.
The newly approved Abbott test, BinaxNOW, is a step toward more accessible antigen testing. It doesnt require a machine to read the results and still, according to data presented to the FDA, has a 97 percent specificity level compared with PCR tests. It is also $5 for one test, and the company says they will be able to ship 50 million of them a month this fall.
The downside is it is only available with a prescription, and it needs to be given by a health care professional or other trained individual (such as a pharmacist or workplace health specialist). The test requires a nasal swab and a small amount of specialized chemicals known as reagents. And it is only to be used for people who developed Covid-19 symptoms within the past week, making it inapplicable for broader population-wide screening.
With an over-the-counter test, we might also lose a lot of important public health disease surveillance data. If people are testing positive at home or even in a public setting and not following up with a health care worker or public health department, their case might not get counted or their contacts traced. You would need to have a link back to public health, Smith says. They would also want to get information on the test that was performed so they could properly interpret the results.
This is where our existing PCR testing capacity could run backup. Smith explains that a positive antigen test result could be a trigger to get a PCR test to confirm the infection. It could also possibly reduce the number of PCR tests that are run, potentially speeding up delivery of those results as well.
In a perfect world, Smith says, we would have this cheap, at-home test that anybody could take, as frequently as they want, that would give them a quick result. If there is a reason if they have symptoms, if theyve been exposed, or the at-home test comes back positive then they report for PCR.
Tsai agrees PCR tests would still be important. Its really thinking about how we use the pros and cons of all the different tests in a more comprehensive strategy, he says. Lets put these pieces together.
With over-the-counter antigen tests at a regulatory stalemate in the FDAs current authorization system, experts are spitballing alternative routes to getting these tests to the public.
First and foremost, says Mina, government involvement in authorizing new tests is essential to make sure that those that do reach the market work in the way they are supposed to.
One route for this, he proposes, is a new standard by which the FDA could authorize tests, setting a different benchmark for test sensitivity at levels of the virus that are most likely to be transmissible rather than at very low detectable levels. In other words, he notes, the FDA could adjust their language from looking at sensitivity to the virus broadly to sensitivity during peak infection.
The FDA could also reframe the way it characterizes these tests, he says. Instead of being evaluated as an individual diagnostic test, he says, it would essentially be indicated as a transmission-detecting test ... [or] a public health diagnostic test, where the real reason of doing that diagnostic test is one of public health.
Another option would be to designate these tests as surveillance tools rather than diagnostic tests. Under that category, they fall outside the FDAs purview and would more likely be overseen by the CDC and local health departments.
This plan has a big hitch, though. Surveillance test results are aggregated and are not shared back with the individual taking the test. Diagnostic tests, on the other hand, are those which have results given back to the individual so that they might take a specific action. The latter is, of course, the goal here (to let people know, for example, if they need to start self-isolating).
Its this awful catch-22 that could easily be changed if there was a will, Mina says. There just doesnt seem to be much of a will. Or a regulatory framework for thinking about things differently even in the midst of a pandemic, he says.
The FDA has recently conceded that they would consider authorizing a less sensitive test if it were part of a high-frequency testing plan, with each person being tested multiple times (which they call serial testing), Spaulding says.
This, to Mina and others, seems like a step in the right direction, and he is hoping the FDA will provide more detailed guidance on what this would look like in practice.
But the FDA also notes that it would require an application for this sort of serial testing to include the capacity to manufacture a sufficient supply of tests with which to conduct multiple tests per person, Spaulding says.
Mina suggests that this is an arbitrary ask. For other authorized tests, like those using PCR or machine-based antigen detection, the agency has not required makers to show manufacturing capacity or even the supply chain to turn results around in a certain amount of time (which is a key aspect to slowing transmission of Covid-19). Theyre perfectly fine approving tests that might take a year to return results, but thats a 100 percent useless test, Mina says.
Mina also worries that as some of these companies with at-home antigen tests wait for the government to greenlight them, they will decide to make them more complex to meet the current (PCR-based) requirements for diagnostic viral detection.
He calls this going from the sort of instant coffee model of testing (where anyone can take a test, cheaply, pretty much anywhere) to the Nespresso model (where you need access to a specialized machine to get a result).
And slowdowns in rolling out these machine-based antigen tests are already happening. Both BD and Quidel, two companies making rapid antigen tests, are now facing supply chain issues as they try to fulfill orders for their machines and tests, the Wall Street Journal reported.
Tsai notes that public health officials in Florida have been advised to use the Quidel antigen tests only for symptomatic, older adults. Which, he says, makes sense in targeting those most at-risk for complications from the virus, but in some ways also defeats the purpose of the frequent testing strategy.
Mina has been challenging those who are still on the fence about rapid, at-home antigen testing to say whether, in hindsight, it would have been good to have five months ago.
Almost all of them say, yes, that would have been great. Compared to what has happened, of course it would have been great. Now, he says, were in an almost worse spot today, were hitting up against September and October, when coronaviruses can start spreading like crazy. We have to cut our losses and say, okay, we didnt do it five months ago, but we can do it today.
Like the old tree-planting aphorism: The best time to plant a tree may have been 20 years ago, but the second-best time is now. We could potentially save ourselves from ourselves in the fall. But I dont know if its going to happen, frankly, he says.
Part of that reason, he notes, has to do with our general national mindset. I think Americans, including policymakers, are having a hard time coming to terms with the idea that theres actually something bad happening to us.
Just adding this new type of testing on its own, however, wont be enough to get us out of the pandemic. We cant test our way out of it, Smith says. We also need masks, we need distancing.
But, she says, many presymptomatic and asymptomatic cases are not being detected with our current testing strategy. And those people are able to spread the infection further without knowing it. If we cant identify these cases, we are never going to get out of this.

Pediatricians described the findings as reassuring as children accounted for fewer than 1% of some coronavirus cases in England, Wales and Scotland; and only 1% of those children died, the researchers reported.
The researchers -- from various UK institutions -- analyzed data on 651 Covid-19 patients under the age of 19 who were admitted to 138 hospitals across England, Scotland and Wales between January and July. These young patients accounted for 0.9% of all patients in those hospitals at the time, the researchers noted.
Overall, 18% of the young patients needed critical care and "Black ethnicity was significantly associated with admission to critical care," the researchers noted.
The most common symptoms the young patients had were fever, cough, nausea or vomiting, and shortness of breath. The researchers found that 52 patients -- or 11% -- met the criteria for multisystem inflammatory syndrome in children, or MIS-C, a troubling complication of Covid-19 in which different body parts can become inflamed.
Children who may have had MIS-C were significantly older than those who did not and were significantly more likely to be of non-White ethnicity, the researchers found. Children with MIS-C were also five times more likely than others to be admitted to critical care.
Reassured
"However, on balance it's an important study as it is likely most children with significant illness would have presented to the hospitals," said Ramanan, who was not involved in the new study.
Dr. Liz Whittaker, infectious disease lead at the Royal College of Pediatrics and Child Health in Britain, who was not involved in the study, called the findings "reassuring."
It was unclear which patients were admitted to the hospital directly for coronavirus infection and which had been admitted for other reasons but happened to test positive for the virus. More research also is needed to determine whether similar findings among young patients would emerge in other parts of the world.
Minnesotans will likely need two separate doses of a coronavirus vaccine once one becomes available.
Minnesota is one of a handful of states working with the federal government to determine the best way to distribute vaccines against COVID-19 once they become available.
President Donald Trump has speculated a vaccine will be ready by the end of the year, but Minnesota health officials are being more cautious.
Kris Ehresmann, director of infectious disease and epidemiology for the state Department of Health, said past experiences with mass vaccinations have shown it is better to under promise and over deliver.
Prospective vaccines are already being produced by several manufacturers although they continue to be studied for safety and effectiveness. The U.S. government is funding that effort to help speed the availability of a vaccine once it is proven to work its nicknamed Project Warp Speed.
Minnesota health officials met online with leaders from the Centers for Disease Control and Prevention this week to provide input on who should be among the first to be vaccinated against the coronavirus that has killed 1,810 Minnesotans and sickened at least 73,240. Whenever a vaccine becomes available it will almost certainly be in short supply and high demand early on.
Erhesmann said state health officials recommended essential workers such as health care providers and long-term care staffers should be among the first to receive the vaccine.
Until a vaccine is released, state health officials continue to plead with residents to follow community mitigation measures in place to slow the spread of the coronavirus. They include wearing a mask, maintaining a social distance of six feet, staying home when you are sick and diligent hand washing.
COVID-19 has sickened more than 24.5 million worldwide and killed at least 830,000. In the U.S. more than 178,000 have died and 5.8 million have tested positive.
Fox News contributor Dr. Marc Siegel argues 100 million doses of AstraZenecas coronavirus vaccine could be ready by fall and he also discusses whether its possible to have another national lockdown.
Japan has moved to secure a half-billion doses of coronavirus vaccines in a bid to prove it can still host the Summer Olympics next year, according to reports.
Chief Cabinet Secretary Yoshihide Suga claimed that Japan was working with Olympic organizers on how to go ahead with the Games, emphasizing that a vaccine was essential to any effort to stage the event.
Various companies will probably be able to produce a vaccine between the end of this year and next March," Suga told Reuters in an interview this week. There are a lot of considerations, but we want to hold the Olympics at all costs.
The government is on track to secure 521 million doses of five different vaccines, more than four times its population of 126 million. Japan is working on arrangements with companies including Pfizer Inc., AstraZeneca PLCand even local companies such as Shionogi & Co.
You have to bet evenly to avoid getting nothing, said Tomoya Saito, director at Japans National Institute of Public Health.
A broad approach has been the norm, with other nations similarly striking deals with multiple drug makers to ensure that some vaccine will be available as soon as possible.
The U.S. government last month reached a $1.95 billion deal with Pfizer and BioNTech for 100 million doses of their experimental vaccine once it obtains Food and Drug administration approval.
MODERNA SAYS COVID-19 VACCINE SHOWS SIGNS OF WORKING IN OLDER ADULTS
"Adding a vaccine from Pfizer and BioNTech" to the government's Operation Warp Speed inoculation-development program "increases the odds that we will have a safe, effective vaccine as soon as the end of this year, Health and Human Services Secretary Alex Azar said in a statement.
A coalition of European governments have also worked on a deal with AstraZeneca.Spain joined France, Germany, Italy and the Netherlands to secure a supply of 400 million doses of the vaccine as of June 2020.
TRUMP TAPS MCKESSON AS CORONAVIRUS VACCINE DISTRIBUTOR
Prime Minister Shinzo Abe on Friday announced that he would resign as his health condition recently worsened, but his ambition to host the Olympics remains a priority for his government. Abe described his decision as gut wrenching, but necessary, the New York Times reported.
I think the Olympics would have been the one major thing he could point to and say, 'Yes,I did that. I made that happen,' David Leheny, a politics professor at Tokyos Waseda University, told the Times. He still might, and I think whoever the next prime minister is will ensure Abe has a prominent place at the Olympics, but it won't be the same as his being in charge to welcome people.

During his resignation speech, Abe pledged that the government would secure enough vaccine for Japan by the middle of 2021 and that the nation would relax its travel ban from Sept. 1.
UCSF-Led Flu Study Sheds Light on Groups Most Likely to Skip Shots
By Suzanne Leigh
Only one in three U.S. adults received the flu vaccine in 2018, a number that has critical implications for the impending flu season, which threatens to overwhelm medical resources and lead to tens of thousands of deaths at a time when Americans are still reeling from the COVID-19 pandemic.
A new study led by researchers at UC San Francisco has uncovered demographics of those groups who are less likely to receive the flu shot. These findings may inform public health efforts for future COVID-19 vaccines, and raise questions about making both flu and COVID vaccines free of charge and mandatory.
In the study, which publishes in the Journal of General Internal Medicine on Aug. 26, 2020, the researchers evaluated self-reported flu vaccination rates for 2018, which included data from the 201718 flu season (61,000 deaths) and 201819 season (34,200 deaths). The data was recorded in the Behavioral Risk Factor Surveillance System, an annual national survey of 400,000-plus U.S. adults, conducted by state health departments and the U.S. Centers for Disease Control and Prevention.
To achieve herd immunity, we would need to reach about an 80 percent vaccination rate, but no subgroup in our study exceeded 60 percent, said senior author R.

While social distancing, mask-wearing and staying away from crowds will mitigate the spread of the flu, a dangerous type of the flu such as the Spanish flu of 1918 could result in more than 61,000 fatalities, he said referring to the 2017-18 flu season.
To boost vaccination rates, both long-term and short-term interventions are needed, said first author Brandon Yan, a third-year medical student at UC San Francisco. We need a concerted public health campaign that includes public health officials, health care providers and local communities, and reaches those groups most at risk for not getting vaccinated. And we need a proactive primary care outreach strategy to address patient concerns and provide information on how and where to get vaccinated.
In the long-term the goals are loftier, said Yan, and include making the vaccines more accessible, such as expanding availability in grocery store pharmacies, and making them free of charge for those who are uninsured. The ongoing pandemic also raises the issue of whether the flu vaccine and the future COVID-19 vaccine should be mandated, he said. While a federal mandate may be difficult politically, private organizations like colleges and employers could make attendance and employment contingent on getting up-to-date with vaccines.

On May 19, Principia CEO Martin Babler received an unsolicited email from the other side of the planet. It was Sanofi CEO Paul Hudson, and he wanted to know if Babler had time to hop on the phone.
These were busy, likely stressful days for the freshman Big Pharma chief. The week prior, he had caused a minor intercontinental controversy when he told Bloomberg that the US would get first rights to pre-order of their Covid-19 vaccine because BARDA had invested in it at risk. The words did not sit well in Sanofis home country of France, where both the government and chairman Serge Weinberg viewed the company as something of a national institution. President Emmanuel Macron had summoned Hudson to the presidential palace and, according to some local reports, they were meeting that day.

BERLIN (Reuters) - The European Commission is working on signing further contracts with drug companies to secure COVID-19 vaccines, German Chancellor Angela Merkel said on Friday.
On Thursday a spokesman had said that the European Commission has made a 336 million euro ($399.5 million) downpayment to British drug maker AstraZeneca to secure at least 300 million doses of its potential COVID-19 vaccine.
"Further such contracts are in the works," Merkel told journalists at a news conference.

South Africa may sign a deal to help produce a Covid-19 vaccine, potentially boosting access to immunization on a continent with limited manufacturing capacity.
The Coalition for Epidemic Preparedness Innovations, a global organization funding vaccine development, is considering the Cape Town-based Biovac Institute as a fill-finish site, according to Helen Rees, the chair of the organizations Scientific Advisory Board. The state-owned vaccine company is one of a few in the country that has the capacity to package doses into sterile dispensers if clinical trials are successful.
What we are looking at is partnerships, Morena Makhoana, Biovacs chief executive officer, said in response to questions. Once that is signed, we will be able to make an announcement.
A manufacturing agreement will put Africa on a similar path to other continents, much like the clinical trials are doing, he said.
South Africa is the only country in Africa that hosts several clinical studies. It has 2,000 people in the AstraZeneca Plc and University of Oxford vaccine trial, while Novavax Inc. announced earlier this month its starting a Phase 2b clinical trial. One-fifth of the 60,000 volunteers expected to enroll worldwide in Johnson & Johnsons Covid-19 vaccine trial will be in South Africa, said Glenda Gray, the chief executive officer of the South African Medical Research Council.
With 618,286 confirnmed cases, the country has the worlds fifth biggest outbreak.

Covid-19 has really thrown into focus that we have very limited capacity for vaccine manufacturing across the African continent, even in countries like South Africa, said Rees. But theres tremendous interest and we need to have more countries being able to manufacture vaccines.
