The U.S. Centers for Disease Control and Prevention (CDC) has endorsed the use of updated COVID-19 boosters for anyone 12 years and older, following its Advisory Committee on Immunization Practices' (ACIP) recommendation and the U.S. Food and Drug Administration's (FDA) emergency use authorization.

CDC has recommended bivalent formulations of the Moderna COVID-19 vaccine and the Pfizer-BioNTech COVID-19 vaccine for use as a single booster dose at least two months following primary or booster vaccination. These updated boosters are formulated to offer continued protection against the original strain, while also offering better protection against the two lineages of the Omicron variant, BA.4 and BA.5, which represent over 90% of currently circulating virus.

The Moderna COVID-19 booster is authorized for individuals 18 years of age and older and the Pfizer booster is for use for individuals 12 years of age and older.

"The mRNA platform held promise to revolutionize our ability to respond in real time to a swiftly mutating virus. This is a realization of that promise - an updated booster targeting BA.4 and BA.5, made available while those variants represent over 90% of currently circulating virus," said State Health Officer Dr. Joseph Kanter. "I personally plan to get the updated booster and I recommend others who are eligible do so as well."

Based on the data supporting each of these authorizations, the updated boosters are expected to provide increased protection against the currently circulating omicron variant. Individuals who receive a bivalent COVID-19 booster may experience side effects commonly reported by individuals who receive authorized or approved monovalent mRNA COVID-19 vaccines.

“Mix and matching” of the new bivalent booster dose is allowed. One may receive either the Pfizer or Moderna product regardless of which product they received for their primary series and/or prior booster dose.

With authorization of these two bivalent vaccines, the original monovalent mRNA COVID-19 vaccines are no longer authorized as booster doses for individuals 12 years of age and older.

LDH has notified all healthcare providers that this guidance is effective immediately, and they can start ordering the vaccine now. The boosters are expected to become available in the coming days.

Both CDC and LDH recommend that everyone ages 6 months and up get vaccinated against COVID-19 and that everyone ages 5 and up get a booster as soon as they are eligible.
