The National Institutes of Health have started testing a new coronavirus vaccine from Moderna, which is designed to protect against a problematic variant first found in South Africa, the agency said on Wednesday.

According to the agency, the phase 1 study, which is led and funded by the National Institute for Allergies and Infectious Diseases of the NIH, will test how safe and effective the new shot is against the variant known as B.1.351 in around 210 healthy adults .

The study, which has already had some of the first vaccinations, will include approximately 60 adults who participated in Moderna’s original Covid-19 vaccine studies last year, as well as approximately 150 people who have not yet received a Covid-19 vaccine at one Statement.

Returning participants, who were given two syringes of the original vaccine 28 days apart at different doses early last year, will split up.

Some of them get a single booster shot with the new vaccine at a higher dose while others get the new vaccine at a lower dose, the statement said. Remaining participants will be offered a booster shot with the original vaccine “as part of a separate clinical trial protocol”.

Researchers will take blood samples from participants throughout the study, which can be tested against other circulating strains of the virus to see if the vaccine elicits an immune response.

The study will recruit volunteers in the Atlanta, Cincinnati, Seattle and Nashville, Tennessee areas and should be fully enrolled by the end of April, the agency said.

Variant B.1.351, first discovered in South Africa at the end of last year, has given scientists more cause for concern compared to other variants. The variant appears to spread more easily than the original “wild-type” strains, and research shows that it may evade some of the safeguards created by therapeutics and vaccines.

So far, 312 Covid-19 cases with variant B.1.351 have been identified in the United States, according to the latest data from the Centers for Disease Control and Prevention.

“Preliminary data shows that the COVID-19 vaccines currently available in the US should provide adequate protection against SARS-CoV-2 variants,” said NIAID Director and Chief Medical Officer of the White House, Dr. Anthony Fauci, in a statement.

“However, out of caution, NIAID has continued its partnership with Moderna to evaluate this variant vaccine candidate should an updated vaccine be required,” said Fauci.

The US Food and Drug Administration has already announced that it will accelerate the approval process for the updated vaccines, which target the problematic variants, so that no lengthy clinical trials are required.

However, an independent safety monitoring committee will continue to monitor the trials to ensure the shots are safe, the NIH statement said.

Right here is How Johnson & Johnson’s Vaccine Differs from Pfizer and Moderna’s

A third effective weapon was added to the American arsenal against the coronavirus on Saturday when the Food and Drug Administration granted emergency approval for a vaccine developed by Johnson & Johnson.

The company announced it would begin shipping millions of cans earlier this week and ship 100 million cans to the US by the end of June. Together with 600 million doses of the country’s first two approved vaccines, manufactured by Pfizer-BioNTech and Moderna, due to be dispensed over the next four months, that should be enough to cover every American adult who wants to be vaccinated.

The new vaccine is very different from the two already used in the US. Here’s how they compare.

The Johnson & Johnson vaccine is given in one shot, while the Pfizer BioNTech and Moderna vaccines are given in two shots several weeks apart.

The Johnson & Johnson vaccine uses a different method to prepare the body to fight Covid-19: a viral vector called Ad26. Viral vectors are common viruses that have been genetically modified so that they do not cause disease, but can still cause the immune system to build up its defenses. The vaccines Pfizer-BioNTech and Moderna use messenger RNA for this.

The Johnson & Johnson vaccine is found to be highly effective in preventing serious illness and death, as are Pfizer-BioNTech and Moderna vaccines. It’s also very effective in preventing milder diseases, albeit a little less than either of these. It appears to be good against the highly contagious variant B.1.351, which was first identified in South Africa and has caused problems at least one other vaccine candidate.

The Johnson & Johnson vaccine does not need to be stored at extremely low temperatures like the Pfizer BioNTech vaccine. It can be safely stored in a regular refrigerator for three months, much longer than the Moderna vaccine, which spoils after a month if left frozen.

The Johnson & Johnson vaccine appears to be less susceptible than the Pfizer-BioNTech and Moderna vaccines to causing the types of side effects that need to be monitored after injection, which may make it more suitable for drive-through vaccination site use. It has been reported that side effects tend to be more felt after second doses that the Johnson & Johnson vaccine doesn’t need.

Moderna’s Easy Repair to Vaccine Provide: Extra Doses in Every Vial

Moderna is asking U.S. regulators to agree to what could be a remarkably simple proposal to speed up Americans’ immunization against the coronavirus: fill the empty space in the vials with up to 50 percent more doses.

The Food and Drug Administration could decide in a matter of weeks whether Moderna, a Massachusetts-based biotech company that develops one of two state-approved Covid vaccines, can increase the number of doses in its vials from up to 15. Moderna has ramped up production of its vaccine, but the process of filling, capping and labeling millions of tiny vials has proven to be a roadblock. The company could produce more if regulators allow it to make fuller vials, Ray Jordan, a Moderna spokesman, said late Monday.

While it’s not clear how quickly Moderna could adjust its production, any spike could be extremely welcome news in the campaign to contain a pandemic that has killed more than 443,000 people in the US alone.

“That just makes a lot of sense,” said Dr. Nicole Lurie, who was Assistant Secretary of Health for Preparedness and Response under President Barack Obama. If Moderna can use the same size vial and the same production lines that are already running, she said, “It’s a relatively simple and straightforward solution.”

Moderna has given up about 46 percent of the vaccine previously administered in the United States, according to the Centers for Disease Control and Prevention. The remainder comes from Pfizer-BioNTech, the only other vaccine developer to receive emergency clearance.

Both vaccines require two doses, and both companies have promised to deliver 200 million doses by July. That would be enough to cover roughly three-quarters of the nation’s adults. If Moderna can deliver cans faster, that schedule could accelerate.

The Biden administration is looking for a way to strengthen production, for example for obstacles in the “filling and finishing” phase of production. Although this stage of the nuts and bolts receives less attention than the manufacturing process of the vaccine itself, it has been identified as a production limitation for years.

Moderna has discussed the possible change with the Food and Drug Administration but has not yet provided manufacturing data for support, according to those familiar with the discussions. Federal regulators may be receptive to the idea of ​​more doses in each vial, but could prevent a 50 percent increase and instead approve a more modest number of additional doses.

The industry standard has long been 10 doses per vial, and federal regulators may fear that having too many extra punctures by needling the rubber cover of the vial and the time it takes to extract more doses increases the risk of contamination of the vaccine with Bacteria could increase.

At some point, too much liquid can cause a vial to break. Moderna has tested what happens when additional doses are added and found the limit to be 15, according to people familiar with the company’s operations and not authorized to speak publicly.

Moderna’s proposal for a five dose increase was previously reported by CNBC.

Packing more vaccines in each vial is one of several options the White House and health officials are considering to ramp up production before spring, when authorities expect a renewed spike in infections from emerging variants of the coronavirus. Some ideas, such as combining fractions of doses left over in vials, have been suggested and discarded.

Pfizer is unable to increase the amount of vaccine in its vials because its manufacturing is geared towards a specific vial size that can only hold about six doses. Moderna’s vial is large enough to hold more than the 10 doses currently allowed, so it can add more without creating a new production line.

When asked about Moderna’s proposal, a White House spokesman said Monday that “all options are on the table”.

Prashant Yadav, who studies healthcare supply chains at the Washington Center for Global Development, said Moderna could potentially make more of its vaccine “relatively quickly” if it were given the green light to add doses to each vial.

Answers to your vaccine questions

Am I eligible for the Covid vaccine in my state?

Currently more than 150 million people – almost half of the population – can be vaccinated. But each state makes the final decision on who goes first. The country’s 21 million healthcare workers and three million long-term care residents were the first to qualify. In mid-January, federal officials asked all states to open eligibility to anyone over 65 and adults of any age with medical conditions that are at high risk of becoming seriously ill or dying of Covid-19. Adults in the general population are at the end of the line. If federal and state health authorities can remove bottlenecks in the distribution of vaccines, everyone over the age of 16 is eligible as early as spring or early summer. The vaccine has not been approved in children, although studies are ongoing. It can take months before a vaccine is available to anyone under the age of 16. For the latest information on vaccination guidelines in your area, see your state health website

Is the Vaccine Free?

You shouldn’t have to pay anything out of pocket to get the vaccine, despite being asked for insurance information. If you don’t have insurance, you should still get the vaccine for free. Congress passed law this spring banning insurers from applying cost-sharing such as a co-payment or deductible. It consisted of additional safeguards prohibiting pharmacies, doctors, and hospitals from charging patients, including uninsured patients. Even so, health experts fear that patients will end up in loopholes that make them prone to surprise bills. This may be the case for people who are charged a doctor’s visit fee with their vaccine, or for Americans who have certain types of health insurance that are not covered by the new regulations. When you get your vaccine from a doctor’s office or emergency clinic, talk to them about possible hidden costs. To make sure you don’t get a surprise invoice, it is best to get your vaccine at a Department of Health vaccination center or local pharmacy as soon as the shots become more widely available.

Can I choose which vaccine to get?How long does the vaccine last? Do I need another next year?

That is to be determined. It is possible that Covid-19 vaccinations will become an annual event just like the flu vaccination. Or the vaccine may last longer than a year. We’ll have to wait and see how durable the protection from the vaccines is. To determine this, researchers will track down vaccinated people to look for “breakthrough cases” – those people who get Covid-19 despite being vaccinated. This is a sign of a weakening of protection and gives researchers an indication of how long the vaccine will last. They will also monitor the levels of antibodies and T cells in the blood of people who have been vaccinated to see if and when a booster shot might be needed. It is conceivable that people might need boosters every few months, once a year, or just every few years. It’s just a matter of waiting for the data.

Does my employer need vaccinations?Where can I find out more?

But he said it wasn’t an instant change. “I don’t think Moderna has a surplus,” he said.

Dr. Lurie, an advisor to the Coalition for Epidemic Preparedness Innovations, known as CEPI, said that during the federal government’s H1N1 swine flu response, the problem of filling and completion created a “major bottleneck” with a limited supply of vaccines.

She said that at the start of the coronavirus pandemic at CEPI, there was discussion about which vial size would be suitable for mass vaccination: five, 10 or 20. Last year, a global shortage of glass vials became apparent due to negotiations between the federal government and vaccine manufacturers , which added further stress to drug companies developing coronavirus vaccines.

Mr Yadav said the finish-and-fill process has been automated to prevent contamination and ensure precise dosing of the microgram. It can fill up to 1,000 vaccine bottles per minute at top speed, he said.

A 15-dose vial made a compromise, he said. There could be more waste if healthcare professionals run out of people to be vaccinated and have to discard the remaining doses. But during a raging pandemic, experts said that could be a risk federal health officials would take.

Dr. Moncef Slaoui, who led the Trump administration’s vaccine development program and is an advisor to the Biden administration through next week, said other big drug companies like Merck or GlaxoSmithKline could potentially be able to end some of the fill and leg burden.

“It’s a more general type of manufacturing activity,” he said.

French drug maker Sanofi announced last week that it would produce more than 100 million doses of the Pfizer BioNTech vaccine starting this summer to meet demand in Europe. Company employees said Sanofi will fill and package vials at a Sanofi facility in Frankfurt, near BioNTech’s German headquarters. BioNTech, Pfizer’s German partner, developed the vaccine.

Dr. Fauci, Azar obtain Moderna’s Covid vaccine as rollout begins

[The stream is slated to start at 10:00 a.m. ET. Please refresh the page if you do not see a player above at that time.]

The director of the National Institute for Allergies and Infectious Diseases, Dr. Anthony Fauci, US Secretary of Health Alex Azar and other senior health officials are expected to receive the Covid-19 vaccine from Moderna on Tuesday morning.

The director of the National Institutes of Health, Dr. Francis Collins, is also said to be shot. According to the NIH, six health care workers at the NIH Clinical Center will also receive the Moderna vaccine, which the Food and Drug Administration approved for emergency use last week.

It is the agency’s first delivery of 100 doses, NIH said, and additional NIH Clinical Center health care workers will receive the vaccine after the public event. The agency expects to get a larger shipment from the state of Maryland next week for more frontline healthcare workers.

The event comes after a series of public vaccination ceremonies were held as the first doses of Pfizer and Moderna vaccines were distributed across the country. Senior US officials, including Vice President Mike Pence, US Surgeon General Jerome Adams, and President-elect Joe Biden, have received their vaccines at television events.

Fauci has long said that he will take the vaccine publicly as soon as it becomes available to encourage Americans to get the vaccine.

F.D.A. Clears Moderna’s Covid Vaccine

The Food and Drug Administration on Friday authorized the coronavirus vaccine made by Moderna for emergency use, allowing the shipment of millions more doses across the nation and intensifying the debate over who will be next in line to get inoculated.

The move will make Moderna’s vaccine the second to reach the American public, after the one by Pfizer and BioNTech, which was authorized just one week ago.

The F.D.A.’s decision sets the stage for a weekend spectacle of trucks rolling out as expert committees begin a new round of discussions weighing whether the next wave of vaccinations should go to essential workers, or to people 65 and older, and people with conditions that increase their risk of becoming severely ill from Covid-19.

Jockeying for the next shots in January and February has already begun, even though there is still not enough of the two vaccines for all the health care workers and nursing home staff members and residents given first priority. Uber drivers, restaurant employees, morticians and barbers are among those lobbying states to include them in the next round along with those in the more traditional categories of the nation’s 80 million essential workers, like teachers and bus drivers.

The rapid progress from lab to human trials to public inoculation has been almost revolutionary, spurred by the nation’s urgent need to blunt the pandemic that has broken record after record in U.S. deaths, hospitalizations and economic losses. In the last week alone, there has been an average of 213,165 cases per day, an increase of 18 percent from the average two weeks earlier. And the daily death toll in recent days has surpassed 3,200.

Dr. Anthony S. Fauci, the nation’s top infectious disease expert, called the advent of two vaccines “an historic moment.”

“This to me is a triumph of multiyear investment in biomedical research that culminated in something that was not only done in record time, in the sense of never before has anybody even imagined you would get vaccines to people in less than a year from the time that the sequence was made known,” Dr. Fauci said.

“This is an example of government working. It worked really well,” he added.

Moderna, a company based in Cambridge, Mass., worked with Dr. Fauci’s agency at the National Institutes of Health to create a vaccine that, along with Pfizer-BioNTech’s, shepherds in a new technology based on genetic material called messenger RNA or mRNA. In clinical trials in tens of thousands of volunteers, the vaccines proved 94 to 95 percent effective. Each requires two shots.

Both products are reaching an anxious public before vaccines made with traditional approaches, and have become even more critical as other companies’ efforts have faltered in recent months.

The emergency authorization kicks off a swift and complex drive to distribute some 5.9 million doses of the Moderna vaccine around the country, with shipping to begin on Sunday and deliveries starting on Monday. The first Moderna vaccinations could then be given hours later.

Because Moderna’s vaccine, unlike Pfizer-BioNTech’s, does not need extreme-cold storage and is delivered in smaller batches, states are hoping to provide it to less populated areas, reaching rural hospitals, local health departments and community health centers that were not at the top of the distribution list.

Three places that did not receive the Pfizer-BioNTech vaccine — the Marshall Islands, Micronesia and Palau — will receive the Moderna vaccine for that reason, according to a federal health official familiar with the government’s distribution plans.

And in contrast to Pfizer’s rollout last week, the Moderna vaccine deliveries will be managed by the federal government under the funding of Operation Warp Speed, the administration’s program to develop and distribute vaccines as fast as possible.

Supplies of a second vaccine cannot come soon enough. Several governors and state health officials said on Friday that they were dismayed to learn they would be getting less of the Pfizer-BioNTech vaccine next week than the federal government had promised.

Dr. Mark Levine, commissioner of the Vermont Department of Health, said in a Friday briefing: “All my colleagues in the region are reporting a 25 to 35 percent decrease in their allocation for next week. As we were walking in, I learned as many as 975 doses out of an expected 5,850 doses would not be coming in when we expected. That doesn’t mean we won’t be getting all of those doses. It just means they won’t be coming in when we expected.”

He added, “What everyone around the country is upset about, in addition to just the number, is there’s been no communication, so there’s no understanding of what this really means.”

Answers to Your Vaccine Questions

With distribution of a coronavirus vaccine beginning in the U.S., here are answers to some questions you may be wondering about:

    • If I live in the U.S., when can I get the vaccine? While the exact order of vaccine recipients may vary by state, most will likely put medical workers and residents of long-term care facilities first. If you want to understand how this decision is getting made, this article will help.
    • When can I return to normal life after being vaccinated? Life will return to normal only when society as a whole gains enough protection against the coronavirus. Once countries authorize a vaccine, they’ll only be able to vaccinate a few percent of their citizens at most in the first couple months. The unvaccinated majority will still remain vulnerable to getting infected. A growing number of coronavirus vaccines are showing robust protection against becoming sick. But it’s also possible for people to spread the virus without even knowing they’re infected because they experience only mild symptoms or none at all. Scientists don’t yet know if the vaccines also block the transmission of the coronavirus. So for the time being, even vaccinated people will need to wear masks, avoid indoor crowds, and so on. Once enough people get vaccinated, it will become very difficult for the coronavirus to find vulnerable people to infect. Depending on how quickly we as a society achieve that goal, life might start approaching something like normal by the fall 2021.
    • If I’ve been vaccinated, do I still need to wear a mask? Yes, but not forever. Here’s why. The coronavirus vaccines are injected deep into the muscles and stimulate the immune system to produce antibodies. This appears to be enough protection to keep the vaccinated person from getting ill. But what’s not clear is whether it’s possible for the virus to bloom in the nose — and be sneezed or breathed out to infect others — even as antibodies elsewhere in the body have mobilized to prevent the vaccinated person from getting sick. The vaccine clinical trials were designed to determine whether vaccinated people are protected from illness — not to find out whether they could still spread the coronavirus. Based on studies of flu vaccine and even patients infected with Covid-19, researchers have reason to be hopeful that vaccinated people won’t spread the virus, but more research is needed. In the meantime, everyone — even vaccinated people — will need to think of themselves as possible silent spreaders and keep wearing a mask. Read more here.
    • Will it hurt? What are the side effects? The Pfizer and BioNTech vaccine is delivered as a shot in the arm, like other typical vaccines. The injection into your arm won’t feel different than any other vaccine, but the rate of short-lived side effects does appear higher than a flu shot. Tens of thousands of people have already received the vaccines, and none of them have reported any serious health problems. The side effects, which can resemble the symptoms of Covid-19, last about a day and appear more likely after the second dose. Early reports from vaccine trials suggest some people might need to take a day off from work because they feel lousy after receiving the second dose. In the Pfizer study, about half developed fatigue. Other side effects occurred in at least 25 to 33 percent of patients, sometimes more, including headaches, chills and muscle pain. While these experiences aren’t pleasant, they are a good sign that your own immune system is mounting a potent response to the vaccine that will provide long-lasting immunity.
    • Will mRNA vaccines change my genes? No. The vaccines from Moderna and Pfizer use a genetic molecule to prime the immune system. That molecule, known as mRNA, is eventually destroyed by the body. The mRNA is packaged in an oily bubble that can fuse to a cell, allowing the molecule to slip in. The cell uses the mRNA to make proteins from the coronavirus, which can stimulate the immune system. At any moment, each of our cells may contain hundreds of thousands of mRNA molecules, which they produce in order to make proteins of their own. Once those proteins are made, our cells then shred the mRNA with special enzymes. The mRNA molecules our cells make can only survive a matter of minutes. The mRNA in vaccines is engineered to withstand the cell’s enzymes a bit longer, so that the cells can make extra virus proteins and prompt a stronger immune response. But the mRNA can only last for a few days at most before they are destroyed.

Gov. Charlie Baker of Massachusetts said on Friday, “We’re certainly frustrated,” referring to the reduced number of Pfizer-BioNTech doses his state would receive next week — 42,900 instead of 59,000. Demand for the vaccine is high.

“So far, hospitals are reporting overwhelming acceptance from doctors, nurses and other workers who are eligible to be vaccinated,” he said.

Pointing out how hard hit Wisconsin has been, Gov. Tony Evers complained that the state was receiving significantly less of the Pfizer-BioNTech vaccine than it had been promised — 35,100 doses instead of 49,725. In a statement on Friday, he said, “We call on the federal government to send us more vaccine without delay.”

Because Moderna’s vaccine requires two doses, federal officials are holding another 5.9 million doses for shipment four weeks after the first wave, as the doses are spaced a month apart. The federal government also plans to reserve more than 500,000 doses in case of problems with the initial shipment.

Officials expect to inform states next week the number of doses they plan to send in the second wave of shipments.

The emergency authorization Friday was the product of an F.D.A. review process that compressed an extraordinary amount of work into weeks, and occurred at the same time regulators were poring over materials for the Pfizer-BioNTech vaccine.

The overlap led to a grueling schedule for the reviewers. Large teams organized into specialties — epidemiology, statistics and manufacturing among them — and reviewed Moderna’s application day and night once the company submitted its data in late November.

Among the review’s components were teams that examined company production facilities and clinical trial sites to affirm that records corresponded to the materials Moderna had submitted to federal regulators.

The F.D.A.’s advisory panel also had to consider new information — reports of severe allergic reactions, two in Britain and two in the United States, in people who received the Pfizer-BioNTech vaccine after it was authorized. Although that vaccine is not identical to Moderna’s, they are similar. The agency and the Centers for Disease Control and Prevention are investigating the cases, but say the vaccines can be safely administered to most people who have allergies, with careful monitoring.

The F.D.A.’s authorization also represented a capstone to a sprawling government-led effort that began in January, when scientists at the National Institutes of Health and Moderna designed the vaccine within two days of China’s releasing the genetic sequence of the new virus.

The company had never brought a product to market, giving it an underdog status as its vaccine was tested on the same timetable as Pfizer-BioNTech’s. Moderna enjoyed an unusually intimate relationship with Operation Warp Speed, which has monitored its supply on an almost hourly basis this year. The company benefited from nearly $2.5 billion in federal funds used to buy raw materials, expand its factory and enlarge its work force by 50 percent.

Public health experts and federal officials still estimate that it will be at least six months, if not longer, before most Americans can be vaccinated. And that depends on whether other vaccines in trials are successful and receive emergency approval.

The federal government is counting on building supplies from vaccines under development by several others — one from Johnson & Johnson, one from Sanofi of France and GlaxoSmithKline of Britain, and another from the British-Swedish drug maker AstraZeneca and the University of Oxford.

On Saturday and Sunday, experts advising the C.D.C. will take up Moderna’s vaccine and ultimately vote on the next tiers of people who should get the vaccines. The committee vote on Sunday will most likely set off a frenzy of difficult decision-making at the state level that could be further complicated by bumps in the vaccine production process.

Behind the scenes is McKesson, based in Irving, Texas, one of the country’s largest distributors of drugs and medical supplies. The company has a long history of distributing vaccines and is the largest distributor of the seasonal flu vaccine in the United States.

McKesson also played a central role in the opioid epidemic and is part of a group of companies closing in on a potential $26 billion settlement with state and local governments.

The company will be the main distributor of the Moderna vaccine. Pfizer-BioNTech itself is distributing its vaccine, which needs to be kept at minus 94 degrees Fahrenheit.

McKesson is also producing kits that include the supplies needed to administer both vaccines.

McKesson is assembling the kits at two of its distribution centers, one near Louisville, Ky., a major hub for UPS, and another near Memphis, where FedEx is based.

While McKesson has its own fleet of trucks, it is largely relying on FedEx and UPS to ship the kits and vaccines.

Each kit includes needles, syringes, alcohol prep pads, face shields and surgical masks, administration sheets for health care providers, and vaccination record and reminder cards for patients.

McKesson has outfitted at least two of its distribution centers with specially designed, 10,000-square-foot freezers designed to store millions of doses of the Moderna vaccine. Altogether, McKesson has added more than 3.3 million square feet of space to manage the project.

When the time comes to send the Moderna doses out, McKesson will pack the doses into coolers it sourced from Cold Chain Technologies, a company in Franklin, Mass. Those coolers will be packed with coolant packs, and then sent to administration sites via FedEx and UPS. The coolers also contain monitoring devices that indicate whether the vaccines ever got too warm.

McKesson has hired more than 1,000 people to help with the effort, and expects to hire up more than 2,500 more in the months ahead.
