Seattle Children’s is now offering the Pfizer-BioNTech mRNA COVID-19 bivalent vaccine to individuals 5 years and older. We have the Moderna mRNA COVID-19 bivalent vaccine for individuals 12 years and older. Appointments are required and can be scheduled on our COVID-19 vaccine page.

Individuals are eligible to receive a bivalent booster if it has been at least two months since they have completed their primary vaccination series or have received the most recent booster dose with any authorized or approved monovalent COVID-19 vaccine.

The current monovalent vaccines are no longer authorized for use as boosters in individuals 5 years and older. Children ages 6 months to 4 years remain eligible for the primary, monovalent COVID-19 vaccine series from both Pfizer-BioNTech and Moderna and are not currently authorized for any COVID-19 booster doses.
