Moderna and Pfizer booster shots updated to target Omicron coronavirus subvariants could be available in September, pending signoff by federal health agencies, the US Department of Health and Human Services.
The US Food and Drug Administration advised vaccine makers in June to update the boosters to add an Omicron BA.4 and BA.5 component and create a bivalent booster.
FDA spokesperson says Pfizer and Moderna have indicated that they anticipate the modified vaccines being available as early as September.
US Department of Health and Human Services announced an agreement to purchase 66 million doses of Moderna's bivalent booster shot for potential use in fall and winter.
That's in addition to 105 million bivalent boosters the US government has purchased from Pfizer.
