The Food and Drug Administration expanded authorization of Pfizer-BioNTech's COVID vaccine to enable kids ages 5 to 11 who were vaccinated at least five months ago to get a third shot.

A large share of the nearly 1 million people who died of COVID in the U.S. may have lived if they'd gotten vaccinated. A new analysis shows how many lives could have been saved across the country.
