Effective Monday, May 23, 2022, Seattle Children’s will offer booster doses of the Pfizer COVID-19 mRNA vaccine under an Emergency Use Authorization to children ages 5 to 11 years. The booster dose can be received 5 months after the second dose of the Pfizer vaccine.

The booster is recommended by the FDA, CDC and the Washington State Department of Health to provide further protection against COVID-19 as infections rise across the country. Immunity from the first two doses wanes over time.
