US FDA clears Pfizer Covid-19 booster for older and at-risk Americans

Washington: The US Food and Drug Administration on Wednesday authorized a booster dose of the Pfizer Inc and BioNTech COVID-19 vaccine for those 65 and older, all people at high risk of severe disease, and others who are regularly exposed to the virus.

The decision paves the way for a quick rollout of the booster shots as soon as this week for millions of people who had their second dose of the vaccine at least six months ago.

The change to the vaccine's emergency use authorization will allow boosters for groups such as health-care workers, teachers and day care staff, grocery workers and those in homeless shelters or prisons, FDA acting Commissioner Janet Woodcock said in a statement.
