Boosters and additional doses

Booster dose eligibility

The Centers for Disease Control and Prevention recommends all children 5 years or older and all adults aged 18 years or older get a COVID-19 booster shot.  

If you originally received the Pfizer/BioNTech or Moderna vaccine, you can get a booster shot at least five months after receiving your second dose.

People 5-17 years old are only authorized to get a Pfizer/BioNTech COVID-19 booster.  

On March 29, 2022 the FDA granted approval for individuals aged 50 and older, as well as immunocompromised individuals over the age of 12, to receive a second booster at least four months after their first. 

Boosters - Johnson & Johnson

The CDC states that everyone 18 and older who received the one-dose Johnson & Johnson vaccine should get a booster shot at least two months after their vaccine was administered. It is recommended that people who received a Johnson & Johnson primary dose receive a Pfizer/BioNTech or Moderna booster dose. 

People who received a primary dose and first booster dose of the Johnson & Johnson vaccine are eligible for a second booster dose of only the Pfizer/BioNTech or Moderna vaccine at least four months after receiving the first booster dose. 

Mixing vaccine types

Individuals who are eligible to receive a booster shot can choose a different vaccine type than they received initially. For people who received a Johnson & Johnson primary dose, Pfizer/BioNTech and Moderna vaccines are recommended for booster doses. Those with additional questions or in need of guidance should discuss their options with their healthcare provider.

Additional primary dose guidance for immunocompromised individuals

The CDC recommends that moderately to severely immunocompromised people receive a third primary dose of the Pfizer/BioNTech or Moderna mRNA COVID-19 vaccines at least 28 days after their second dose. The same mRNA vaccine administered for the first and second primary doses should be used for the third primary dose.  

For immunocompromised individuals who receive the Johnson & Johnson vaccine, a second primary dose of an mRNA vaccine is recommended at least 28 days after receiving the Johnson & Johnson vaccine. 

Moderate to severely immunocompromised children 5-11 years old are recommended by the CDC to receive a third primary dose of the Pfizer/BioNTech vaccine 28 days after their second shot. 

Individuals should talk to their healthcare provider about their medical condition, and whether getting an additional primary dose is appropriate for them.
