CDC Advisers Try To Work Out The Details On Booster Shots

The FDA approved a third dose for older Americans and those at high-risk.

With booster doses of Pfizer's COVID-19 vaccine now authorized in the U.S., government advisers reconvened on Thursday to tackle the most contentious question yet: Exactly who should roll up their sleeves right away?

Late Wednesday, the Food and Drug Administration signed off on extra shots of the Pfizer formula for a broad swath of Americans: those 65 and older, people at high risk of severe illness, and health care workers and others in danger of becoming infected on the job.

But that was not the last hurdle. The Centers for Disease Control and Prevention sets final U.S. policy on who qualifies for the extra shot. The CDC's advisers were set to vote Thursday on how many of the roughly 26 million Americans who had their last Pfizer shot at least six months ago should go ahead and get that third dose.
