Frequently Asked Questions About COVID-19 Vaccine Boosters

What is a booster shot?

COVID-19 vaccines continue to work very well at preventing severe illness, hospitalization, and death, including from the Delta variant. A booster shot is an extra dose that helps keep up protection.

Who can get a COVID-19 vaccine booster?

Everyone age 16 and older who has completed their initial COVID-19 vaccination series can get a COVID-19 vaccine booster. It’s especially important for the following people to get a booster because they are at increased risk for severe illness from COVID-19:

When can I get a COVID-19 vaccine booster?

You can get a booster:

  • 6 months after your 2nd dose of the Pfizer-BioNTech or Moderna vaccine.
  • 2 months after your single dose of Johnson & Johnson’s Janssen vaccine.

Which COVID-19 vaccine booster should I get?

You may choose whichever COVID-19 vaccine you want (Pfizer-BioNTech, Moderna, or Johnson & Johnson’s Janssen) to receive as a booster shot. Your booster doesn’t have to be the same vaccine you received before. Pfizer-BioNTech’s COVID-19 vaccine is the only one authorized for people ages 16–17.

Are the COVID-19 vaccine boosters safe?

Yes. Just like other vaccinations, your arm might feel sore after you get your shot. You might also experience flu-like symptoms, such as fever, headaches, body aches, and tiredness. These are normal signs that your immune system is responding to the vaccine. Although these side effects may be unpleasant, you’re not actually sick. And they last a few days at most. Serious side effects from any vaccine, including the COVID-19 vaccines, are very rare.
