People over age 65 and adults at high risk of severe Covid-19 who have previously taken the Pfizer Inc.-BioNTech SE vaccine can receive a booster dose, the Food and Drug Administration said, opening a new and more controversial phase of the U.S. immunization campaign.
The emergency-use authorization also allows boosters for people 18 and older whose occupational exposure to the SARS-CoV-2 virus puts them at elevated risk of serious complications. Booster doses can be given any time at least six months after a person received their second Pfizer shot, the FDA said in a statement.
