Who should get a COVID-19 vaccine booster?

Pfizer booster shots are recommended for some groups of people who received this vaccine: adults ages 65 and older, adults age 50-64 who are at high risk of severe illness, and adults whose jobs put them at higher risk for COVID-19. Younger adults ages 18 to 49 are also recommended to consider a booster based on an assessment of their individual benefits and risks and in consultation with their medical provider. Read more.

I want to get a booster dose, but I’m not eligible yet. Why not?

The Pfizer vaccine was the first COVID-19 vaccine to be authorized in the United States, and its data about booster doses were the first to be available. Guidance and recommendations about boosters for the Johnson & Johnson and Moderna vaccines and whether it’s advisable to mix and match vaccines and boosters are still forthcoming. Read more.

…But can I anyway?

The COVID-19 vaccines have received the most intense safety monitoring in U.S. history, and that monitoring has allowed public health officials to make science-based recommendations that keep people safe. There is limited data about the safety and effectiveness of mixing COVID-19 vaccines, and data is still under review concerning booster doses for the Johnson & Johnson and Moderna COVID-19 vaccines. People are advised against seeking “off-label” uses of the vaccines. Read more.
