The Food and Drug Administration earlier this week authorized the updated Pfizer-BioNTech booster shots. The endorsement from the Centers for Disease Control and Prevention came Thursday, hours after advisers to the CDC voted to recommend reformulated versions of the Moderna and Pfizer-BioNTech COVID-19 vaccines.
Pfizer's CEO says the vaccine maker has asked federal regulators to authorize boosters for 16- and 17-year-olds. Currently, only people 18 and over are eligible for a booster in the U.S.
