On June 17, 2022, the U.S. FDA authorized the Moderna pediatric vaccine for children 6 months to 5 years old under an Emergency Use Authorization (EUA), meaning the vaccine was proven safe and effective for this age group. This vaccine is a two-dose series, and the doses should be administered four weeks apart.
On Dec. 8, 2022, the U.S. FDA authorized an updated, bivalent booster of the Moderna pediatric vaccine for children 6 months to 5 years old to be givenat least 2 months after completion of primary vaccination. This bivalent formula is expected to boost immunity against the original coronavirus strain and protect against the newer Omicron variants that cause most cases. Information about dosage and efficacy can be found in the vaccine’s U.S. FDA fact sheet.
