Pediatric COVID-19 Vaccine

Updated COVID-19 Booster FAQ

In September 2022, the FDA and CDC approved a new type of COVID-19 vaccine booster called a bivalent booster. This booster targets the two latest Omicron COVID-19 strains – BA.4 and BA.5 – as well as the original COVID-19 virus strain.

Who is eligible for the new booster?
The Moderna version of the bivalent booster is approved for people 18 and older, while the Pfizer bivalent booster is approved for people ages 12 and older.
You are eligible for the updated bivalent booster if you:

  • Are 12+ years of age
  • Had a primary series of two Pfizer or Moderna COVID-19 vaccines or one Johnson & Johnson vaccine
  • Had your last dose of COVID-19 vaccine (first, second, third, or booster dose) at least two months ago

Should I get the new booster even if I've already had a COVID-19 booster?
You should get the updated bivalent booster even if you already had a COVID-19 booster dose. This is because any booster given before September 2022 didn’t include specific protection against Omicron variants.

You should also get the new booster even if you got more than one COVID-19 vaccine booster dose before, for better protection against the current COVID-19 strains.

Should I get the new booster even if I've already had a COVID-19 infection?
Yes. The bivalent booster will increase your immune protection against COVID-19, strengthening the protection you get from being infected with COVID-19.

You can get the vaccine booster as long as you're not currently in isolation with COVID-19 and have recovered. Some people might choose to wait two months after their infection, which is the length of time recommended between your last dose of the COVID-19 vaccine and a bivalent booster.

What if my child is under 12 years old? Should they get a booster?
Anyone over five years old is strongly encouraged to get a COVID-19 vaccine booster. Children between the ages of 5 and 11 years old will get the monovalent booster, which is the booster previously given to people of all ages.
