BETTER BOOSTERS: Updates on the Reformulated COVID-19 Boosters

On 9/1/22, the CDC endorsed the Food and Drug Administration’s emergency use authorizations for two reformulated COVID-19 booster shots, one from Moderna and another from Pfizer/BioNTech.

The new boosters are “bi-valent”: they target both the original strain of SARS-CoV-2 as well as two versions of the Omicron variant – BA.4 and BA.5.

The Moderna COVID-19 Vaccine, Bivalent is authorized for use as single booster dose in individuals 18 years of age and older.

The Pfizer-BioNTech COVID-19 Vaccine, Bivalent is authorized for use as a single booster dose in individuals 12 years of age and older.

The FDA no longer authorizes the use of the existing booster formulations in individuals ages 12 and over.

Eligible individuals must have completed a primary COVID-19 vaccine series to get them. The vaccines used in the primary series are not changing.

According to the FDA, people who received a primary vaccine dose or a booster dose should wait two months before getting the new booster.
