On Sept. 1, 2022, the Centers for Disease Control and Prevention endorsed the use of updated COVID-19 booster shots that are specifically tailored to combat the two most prevalent omicron subvariants, BA.4 and BA.5. The decision comes just a day after the Food and Drug Administration’s emergency use authorization of the shots. The CDC’s backing will enable a full roll-out of the reformulated vaccines to begin within days.
The new booster shots – one by Moderna and another from Pfizer-BioNTech – come as more than 450 people are still dying of COVID-19 every day in the U.S.
