WASHINGTON — The U.S. has its first fully approved vaccine against COVID-19, with federal health officials announcing Monday the approval of Pfizer-BioNTech’s two-dose vaccine.
The green light from the U.S. Food and Drug Administration to move Pfizer’s vaccine from emergency use to full approval is a milestone in the national pandemic response, and one that comes as the country battles another surge in infections and hospitalizations because of the delta variant.
The Pfizer vaccine is the only one of the three shots being used under an emergency authorization so far to gain the FDA’s full approval. Moderna also has submitted an application for full approval, while Johnson & Johnson has said it will do so for its one-dose shot by the end of the year.
The approval represents a lightning-speed process at the FDA, which condensed a review process that typically would take roughly eight months in just three months.
As they sought to conduct that approval at a much faster pace due to the pandemic, public health officials also attempted not to undermine confidence among those who have said they were waiting to see the agency give a full sign-off before getting a jab.
“The moment you’ve been waiting for is here,” President Joe Biden urged Americans during a news conference Monday. “It’s time for you to go get your vaccination, and get it today.”
The vaccine’s full approval also may mean more Americans will be required to receive a vaccine in order to attend school, go to work, go out to eat, or attend concerts and other large-group events.
Members of the military are the latest to be subject to a vaccine mandate. Pentagon officials said Monday that a timeline for the new requirement is under discussion.
Pfizer shot to be marketed as Comirnaty
The Pfizer vaccine was the first of the three current COVID-19 shots to receive emergency approval in mid-December. Initially authorized for those 16 and older, that authorization was expanded in May to include shots for those 12 through 15 years of age.
Monday’s approval changes the status for the shot’s use in those 16 years and older. While the vaccine will now have a new brand name — Comirnaty — nothing about the vaccine formula itself has changed.
The process involved significant data reviews, examining hundreds of thousands of pages of information from the clinical trials and visits to sites where the vaccine was studied and produced. Peter Marks, director of FDA’s Center for Biologics Evaluation and Research, told reporters that more than half of the clinical trial participants have been tracked for any safety concerns for at least four months, and 12,000 have been followed for six months.
The full approval does not yet extend to vaccines for those between 12 and 15 years old, who can still receive Pfizer shots through the emergency-use authorization.
Pfizer also is expected to apply this fall for using the vaccine in those under age 12, who are not yet eligible for any of the COVID-19 vaccines.
Federal regulators also have approved a third booster dose of the Pfizer shot for those who are immunocompromised. Additional boosters are likely to be approved for the broader population, beginning eight months after a second dose, but regulators at the FDA and Centers for Disease Control and Prevention have not yet set dates for approving those boosters.
Approval effect on vaccination rate
Nationally, vaccination rates, which had lagged since a spring peak, have been rising again, with 62% of those over age 18 now fully vaccinated. Six million shots have been administered in the last seven days, marking the highest seven-day total in a month and a half, Biden said Monday.
Those rising numbers come as the delta variant has wreaked havoc across the country, filling hospital beds and causing a rise in pediatric admissions due to COVID-19. The vast majority of those hospital admissions are among Americans who have not yet been vaccinated.
Among those who have not received a COVID-19 vaccine, three in 10 said in a June tracking survey by Kaiser Family Foundation that they would be more likely to get vaccinated if one of the vaccines authorized for emergency use were to receive full approval from the FDA.
The National Governors Association praised the FDA’s approval in a statement Monday, calling it “another tool that will help combat hesitancy.”
“We have heard from many of our residents as we have traveled across our states and territories, held town halls, and met with residents, who are hesitant to get vaccinated because they are awaiting full approval of the vaccines,” said Govs. Asa Hutchinson of Arkansas and Phil Murphy of New Jersey, who lead the NGA, adding that the approval helps to address some objections and safety concerns.
More vax mandates to come?
As he urged unvaccinated Americans to get their shot, Biden on Monday also praised governors, mayors and companies that have required their employees and patrons to be vaccinated against COVID-19.
The full approval of Pfizer’s shot may spur an uptick in vaccine requirements in the public and private sector, which in turn may help drive up vaccination rates, said Mark McClellan, a Duke University health policy expert and former FDA commissioner.
“While we already had a number of businesses, schools, entertainment venues requiring vaccination or proof of a negative test or something like that, those numbers are going to go up significantly,” McClellan said. “That probably is going to drive the bigger impact of the full approval on vaccination rates in this country, probably even more than the remaining people who are having doubts and potentially willing to be convinced.”
