When will we have an
FDA-approved vaccine? |
More
than 339 million doses of Covid-19 vaccine have been administered across the
US, and while studies show that the three vaccines authorized for emergency
use in the United States work and are safe, none has been formally approved
by the US Food and Drug Administration. By all
accounts, the approval process for the
vaccines is moving faster than it ever has before. However, the
FDA has yet to disclose a timeline for when its work will be complete, and
data is still being reviewed. Last
Wednesday, President Joe Biden told a CNN town hall that he expects Covid-19
vaccines could get full approval "quickly.” Based on conversations he’s
had with experts, he expects a final nod soon. "They're
not promising me any specific date, but my expectation, talking to the group
of scientists we put together ... plus others in the field, is that sometime,
maybe in the beginning of the school year, at the end of August, beginning
September, October, they'll get a final approval," Biden said. The
Covid-19 vaccines received authorization based on interim data that showed
the vaccines were safe and effective for only about three months. For full
approval, the FDA has at least six months of efficacy data to review. And in
addition to the data, the FDA also has to validate the process to make the
vaccines. "Whether it's the computers that are being used or cleaning
out the vats, or whatever it is, it's a lot of boxes to tick to ensure that
there's consistency in each lot to the next," said Dr. Paul Offitt, an
FDA adviser. And
while a vaccine for those 12 and older might be approved soon, more safety
and efficacy data is needed for children ages 5-11. Multiple people familiar
with the Pfizer and Moderna pediatric trials told The New York Times that the
FDA has asked the two companies to enlist more trial participants so they can
better detect rare side effects. |
