Based on updated guidance from the Centers for Disease Control and Prevention (CDC) and the U.S. Food & Drug Administration (FDA), UW Medicine is now providing a single booster dose of the Pfizer-BioNTech COVID-19 vaccine to all children ages 5 to 11 who have completed their primary, two-dose series at least five months prior.

The Pfizer-BioNTech vaccine is the only COVID-19 vaccine authorized for this age group as a primary series or as a booster at this time.

Booster scheduling

To schedule your child’s booster, please call 844.520.8700 or book online.

Appointments are available at UW Medical Center – Montlake, Harborview Medical Center and UW Medicine Primary Care clinics. We also continue to provide primary series vaccinations to all individuals 5 and older at these locations.

Please note that children under 5 are not currently eligible for the vaccine.

Boosters are a safe and effective way of reducing the risk of serious COVID-19 illness in all eligible age groups, including children. With case counts again rising locally, we continue to follow CDC and FDA guidance in recommending all eligible individuals stay up to date on their COVID-19 vaccines as the best protection against severe disease.
