In a surprising vote, a panel of advisers to the Food and Drug Administration on Friday recommended against approval of a booster dose of the Pfizer-BioNTech COVID-19 vaccine for people 16 years and older.
The 16-2 vote against broad use of the booster, which would be given about six months after completion of the two-dose immunization regimen, dealt a setback to Pfizer and complicates the FDA’s approach to boosters.
After a brief intermission following the rejection, FDA officials returned to the meeting with a revised booster question. The panel then voted 18-0 in support of the agency authorizing a booster shot of the vaccine for people 65 and older or at high risk of severe COVID-19.
The FDA then polled the panel members for advice on other groups of people who might be considered for a booster. Though not an official vote, the panel members unanimously supported authorization of a Pfizer booster dose for health care workers or others at high risk of occupational coronavirus exposure.
The agency typically follows the advice of its advisory committees, though it isn’t required to.
