Updated bivalent Pfizer-BioNTech and Moderna COVID-19 boosters are now authorized by the FDA and recommended by the Centers for Disease Control and Prevention (CDC) for all eligible individuals.
New:
- Children ages 6 months through 5 years who previously completed a Moderna primary series are eligible to receive a Moderna bivalent booster 2 months after their final primary series dose.
- Children ages 6 months through 4 years who are currently completing a Pfizer-BioNTech primary series will receive a Pfizer-BioNTech bivalent vaccine as their third primary dose. Children 6 months through 4 years of age who have already completed
their three-dose primary series with the original (monovalent) Pfizer-BioNTech COVID-19 Vaccine will not be eligible for a booster dose of an updated bivalent vaccine at this time.
The Pfizer-BioNTech bivalent vaccine continues to be authorized for administration at least two months following completion of primary or booster vaccination in children down to 5 years of age.
The monovalent mRNA COVID-19 vaccines are no longer authorized as boosters. Only the updated/bivalent COVID-19 vaccines are authorized as boosters. Both the Moderna and Pfizer monovalent COVID-19 Vaccines continue to be authorized for primary series
administration in individuals six months of age and older.
Novavax monovalent COVID-19 boosters are now available to people ages 18 years and older if they meet all three of these requirements:
- they have completed a primary series vaccination AND
- they have not previously received any COVID-19 booster(s) AND
- they cannot or will not receive an updated/bivalent mRNA booster
The monovalent Novavax booster dose is administered at least 6 months after completion of any primary series and cannot be used in people who previously received any booster dose(s).
