The Food and Drug Administration (FDA) has authorized second booster shots, and fourth shots overall, of the Pfizer-BioNTech and Moderna COVID-19 vaccines for Americans 50 and older, the companies announced Tuesday morning.

Immunocompromised adults over the age of 12 can also now receive an additional Pfizer dose, and those 18 and older are eligible for Moderna’s fourth shot. The second booster is to be distributed four months after the first.

Americans 12 and older with particularly weak immune systems because of a serious condition are now eligible for a fifth shot four months after the previous, the agency also decided.

The FDA approval comes as uptake for the additional shots in the U.S. wanes and both Covid cases and deaths reach the lowest points since well before the Omicron-fueled winter virus surge.
