On Wednesday the FDA issued an EUA (Emergency Use Authorization) authorizing the Moderna & Pfizer-BioNTech Bivalent COVID-19 Vaccines for Use as a Booster Dose. Yesterday, in a 13-1 vote, the CDC's ACIP (Advisory Committee On Immunizations) also recommended these boosters be used.
While Pfizer and Moderna have run clinical trails on an earlier version (with the BA.1 mRNA component), it isn't known how much more effective these reformulated bivalent booster shots will be.You can view the extensive slide presentations from that meeting at this LINK.
Like the seasonal flu vaccine, we probably won't have that answer until sometime this winter.
Late yesterday, the CDC's director Dr. Rochelle P. Walensky M.D., M.P.H. added the final endorsement (see below), which will permit the deployment of these new boosters, starting next week.

Today, CDC Director Rochelle P. Walensky, M.D., M.P.H., endorsed the CDC Advisory Committee on Immunization Practices’ (ACIP) recommendations for use of updated COVID-19 boosters from Pfizer-BioNTech for people ages 12 years and older and from Moderna for people ages 18 years and older.
Updated COVID-19 boosters add Omicron BA.4 and BA.5 spike protein components to the current vaccine composition, helping to restore protection that has waned since previous vaccination by targeting variants that are more transmissible and immune-evading.
In the coming weeks, CDC also expects to recommend updated COVID-19 boosters for other pediatric groups, per the discussion and evaluation of the data by ACIP on Sept. 1, 2022. When data are available and FDA authorizes these other types of COVID-19 boosters, CDC will quickly move to help make them available in the United States.
The Food and Drug Administration’s (FDA) authorization of updated COVID-19 boosters, and CDC’s recommendation for use, are critical next steps forward in our country’s vaccination program—a program that has helped provide increased protection against COVID-19 disease and death.
The following is attributable to Dr. Walensky:
“The updated COVID-19 boosters are formulated to better protect against the most recently circulating COVID-19 variant. They can help restore protection that has waned since previous vaccination and were designed to provide broader protection against newer variants. This recommendation followed a comprehensive scientific evaluation and robust scientific discussion. If you are eligible, there is no bad time to get your COVID-19 booster and I strongly encourage you to receive it.”
