U.S. FDA authorizes Moderna, Pfizer updated COVID boosters for 6 months old

The U.S. Food and Drug Administration on Thursday authorized updated COVID-19 booster shots from Moderna and Pfizer and its partner BioNTech for children as young as 6 months of age.

The amended authorizations allow use of Moderna's bivalent shot in children 6 months through 5 years of age, while the Pfizer/BioNTech vaccine can be given to those aged 6 months through 4 years. Pfizer's shot can be administered as the third shot for those eligible and have not completed their primary vaccination series, the agency added.
