- Review the recommendations for use of COVID-19 vaccine booster doses in adults based on previous vaccination history.
Updated: December 9, 2021
On November 19, the FDA expanded the Emergency Use Authorizations (EUAs) for the mRNA-based COVID-19 vaccines manufactured by Pfizer/BioNTech (Comirnaty) and Moderna (Spikevax) to include administration of a booster dose for all adults ≥18 years old after primary immunization with either the same COVID-19 vaccine or a different one.1 Booster doses of these vaccines were previously authorized only for select populations (age ≥65 years or persons at high risk for severe COVID-19). The EUA for the adenovirus-based vaccine manufactured by Johnson & Johnson was amended in October 2021 to include administration of a booster dose for all adults ≥18 years old after primary immunization with the Johnson & Johnson vaccine.2,3
Note: On December 9, the FDA expanded the EUA of the Pfizer/BioNTech COVID-19 to include a booster dose for adolescents 16-17 years old; the CDC endorsed use of booster doses in this age group. A full review of such use will be published in a future issue.
The CDC recommends a COVID-19 booster dose for all adults ≥18 years old.4 A single booster dose of either mRNA-based COVID-19 vaccine can now be administered ≥6 months after a primary series of an mRNA-based vaccine or ≥2 months after a single primary dose of the Johnson & Johnson vaccine in all adults ≥18 years old.5,6 A single booster dose of the adenovirus-based COVID-19 vaccine can be administered to any adult ≥2 months after a single primary dose of the Johnson & Johnson vaccine or ≥6 months after a primary series of an mRNA-based vaccine (see Table 1).7
