Acting FDA Commissioner, Janet Woodcock, said boosters would be allowed for groups including health care workers, teachers, supermarket workers and people in homeless shelters or prisons.
It was based on scientific evidence and the advisory committee’s recommendation, she said.
“We will continue to evaluate the rapidly changing science and keep the public informed,’’ Woodcock said.
The FDA’s expert panel concluded Friday that the data did not justify introducing booster shots to the general population over 16.
U.S. President Joe Biden had already announced a start date of September 20, for all those vaccinated eight months ago to get a third dose.
