What is a booster dose? Why would I need one?
For some viruses, the protection we get from a vaccine starts to wear off over time. An additional dose of the vaccine may be needed to boost your immune response and make sure we're protected from the virus. Boosters are common for many vaccines, like Tdap (tetanus, diphtheria, and pertussis).
Available data right now shows that all three of the COVID-19 vaccines approved or authorized in the United States continue to be highly effective in reducing risk of severe disease, hospitalization, and death, even against the widely circulating Delta variant. Vaccination remains the best way to protect yourself and reduce the spread of the virus and help prevent new variants from emerging.
Who is currently eligible for a booster dose of COVID-19 vaccine?
Learn more about eligibility, safety and more on the CDC website.
Pfizer & Moderna

How can I get my booster shot?
COVID-19 booster shots are administered anywhere the COVID-19 vaccine is available. Individuals do not need to get their booster shot at the same location they received their initial series.

Can I get a booster shot and a flu shot at the same time?
Yes, you can get a COVID-19 vaccine and a flu vaccine at the same time.
What is "mixing and matching"?
"Mixing and matching" is getting a different type of COVID-19 booster than the type you received for your initial vaccine series. CDC advises to get the same type for your booster as the type of your original vaccination but allows people to mix and match if needed.
