The FDA authorized the use of new Covid-19 booster shots Wednesday to specifically target the ‘Omicron Subvariants’ of the virus that now account more nearly all new infections in the United States.

“The Food and Drug Administration on Wednesday authorized the first redesign of coronavirus vaccines since they were rolled out in late 2020, setting up millions of Americans to receive new booster doses targeting Omicron subvariants as soon as next week,” reports the New York Times.

“The agency cleared two options aimed at the BA.5 variant of Omicron that is now dominant: one made by Pfizer and its German partner BioNTech for use in people as young as 12, and the other by Moderna, for those 18 and older. The doses can be given at least two months since people last received a booster dose or completed their initial series of vaccinations,” adds the newspaper.

“As we head into fall and begin to spend more time indoors, we strongly encourage anyone who is eligible to consider receiving a booster dose,” Dr. Robert M. Califf, the F.D.A. commissioner, said in a statement on Wednesday.
