Booster Shots

The authorized COVID-19 vaccines are effective at reducing the risk of severe disease, hospitalization, and death, even against the highly contagious variants.

We encourage anyone who is eligible to get their booster shot as soon as possible.

Bivalent booster shots are authorized by the U.S. Food and Drug Administration (FDA) and recommended by the Centers for Disease Control and Prevention (CDC) for all individuals aged 12 years and older (see details below for eligibility).

  • Individuals aged 18 years and older who received the Janssen (Johnson & Johnson) vaccine can get their booster shot at least 2 months after their initial vaccine.
  • For children 5 to 11 years of age, the original monovalent mRNA vaccine should still be used for primary series vaccination and as booster doses. The bivalent mRNA vaccine is expected to be approved in younger children in the coming months.
  • The CDC recommends that 5- to 11-year-olds who are moderately or severely immunocompromised get an additional primary dose 28 days after their second shot and a monovalent booster dose at least 3 months after receiving the Pfizer-BioNTech vaccine series.
  • Individuals 18 years of age and older who are moderately to severely immunocompromised are encouraged to get a bivalent booster shot 2 months after their third dose of an mRNA vaccine or 2 months after their second dose of the Jansen vaccine.
  • Individuals 18 years of age and older who received the Novavax vaccine and who are moderately or severely immunocompromised are eligible to receive a bivalent booster of Pfizer-BioNTech or Moderna at least 2 months after their second dose in the primary series.
