Additional Doses & Boosters

Current Recommendations 

Boosters

Following approval from the Food and Drug Administration (FDA) [external link], and the Center for Disease Control and Prevention (CDC) [external link], the new omicron vaccine doses or boosters, are now available.

  • Use the CDC’s COVID-19 Booster Tool [external link] to determine your eligibility for your next COVID-19 vaccine.
  • People ages 5 years and older are recommended to receive the omicron dose at least 2 months after completion of primary series or since their last booster dose.
  • People ages 18 and older who received Janssen COVID-19 vaccine as both their primary series dose and/or booster dose may receive the omicron dose at least 2 months after their last dose of COVID-19 vaccine. 

PFIZER

  • When: 2 months after receiving your last dose for children 5 years and older
  • Who: Everyone 5 years and older

MODERNA

  • When: 2 months after receiving your last dose
  • Who: Everyone 6 years and older

In addition, the CDC recommendations allow for “mixing and matching [external link],” meaning individuals have a choice to receive a different vaccine as a booster than what they originally received.

Additional Doses

  • People ages 6 months and older who are moderately or severely immunocompromised are recommended to receive 3 doses of an mRNA COVID-19 vaccine as a primary series and those 5 years and older are recommended to receive an additional omicron dose at least 2 months after the last dose of a COVID-19 vaccine. 

People who are considered to be moderately to severely immunocompromised may include:

  • Those who have been receiving active cancer treatment for tumors or cancers of the blood.
  • Have received an organ transplant and are taking medicine to suppress the immune system.
  • Have received a stem cell transplant within the last two years or are taking medicine to suppress the immune system.
  • Are moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome).
  • Have advanced or untreated HIV.
  • Are undergoing active treatment with high-dose corticosteroids or other drugs that may suppress your immune response.
