FDA Greenlights Pfizer Booster Shots For Americans As Young As 16

The Food and Drug Administration has greenlighted a request from Pfizer and BioNTech to allow Americans as young as 16 to get a booster shot of their COVID-19 vaccine, the agency announced on Thursday, clearing a key hurdle before that age group can receive the third shot. Boosters were previously OK'd for ages 18 and up.
