The head of the Food and Drug Administration division that approves vaccines said Monday he expects to see at least one company seek emergency authorization for a coronavirus vaccine before the end of the year.
“I think it's possible we'll see something before the end of the year in terms of an emergency use authorization application from some company,” Dr. Peter Marks, director of the Center for Biologics Evaluation and Research (CBER) at the FDA, said in a YouTube interview with the Journal of the American Medical Association.
Five companies have Covid-19 vaccines in Phase 3 trials, the largest and most advanced stages of human testing, in the US. Two of them started in July, so it’s conceivable they could have enough data by the end of the year to ask the FDA to consider emergency authorization, Marks said.
He said the FDA is sticking to a requirement that companies follow volunteers for an average of eight weeks after they get their second dose of vaccine to make sure it’s safe.
“We've made it clear that we want to see a median of about two months of follow up for any of the vaccines that comes in, and while it would be nice to have much more, we have to balance the safety we get out front with the need to try to save lives with a vaccine that’s helping to prevent a virus that’s killing 1,000 or more people a day in the United States,” Marks said.
“(Getting back to normal life) is only going to happen if people have confidence enough to go get vaccinated and we do have a crisis in vaccine confidence.”
Marks said staff are trying to filter out political arguments as they focus on data from clinical trials involving tens of thousands of volunteers.
The FDA’s requirements for an emergency authorization are less strict than for a full Biologics License Application. The process for an EUA will take weeks, while the process for a BLA takes months, Marks said.
FDA officials have repeatedly said they will not skimp on safety considerations for a coronavirus vaccine, even as President Donald Trump repeatedly said a vaccine could be ready by Election Day in November.
