Third Dose mRNA Vaccine Guidance

The third dose of an mRNA COVID-19 vaccine is interchangeable between Pfizer and Moderna and administered eight weeks after completing a primary mRNA COVID-19 vaccine series. Immunocompromised children age 5 and older can get a third dose as well.

Who is considered immunocompromised & recommended to get an additional dose of mRNA COVID-19 vaccine?

  • Receiving active cancer treatment for tumors or cancers of the blood

  • Received an organ transplant & are taking medicine to suppress the immune system

  • Received a stem cell transplant within the last 2 years or are taking medicine to suppress the immune system

  • Moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome)

  • Advanced or untreated HIV infection

  • Active treatment with high-dose corticosteroids or other drugs that may suppress your immune response

What is the difference between a booster and an additional dose?

A COVID-19 booster is given when a person has completed their vaccine series, and protection against the virus has decreased over time. Depending on the original series you had, some details will vary.


An additional dose is administered to people with moderately to severely compromised immune systems. This additional dose is intended to improve immunocompromised people’s response to their initial vaccine series. Depending on the original series given, some details will vary.
