The Centers for Disease Control and Prevention (CDC), the Advisory Committee on Immunization Practices (ACIP) and U.S. Food and Drug Administration (FDA) approved a third dose of COVID-19 mRNA vaccines for people who are moderately to severely immunocompromised on Friday, Aug. 13.

Patients who are eligible have completed a two-dose series of a COVID-19 mRNA vaccine 28 days or more prior to the additional dose AND are considered moderately to severely immunocompromised.

This includes people who have:

  • Been receiving active cancer treatment for tumors or cancers of the blood
  •  Received an organ transplant and are taking medicine to suppress the immune system
  • Received a stem cell transplant within the last two 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

For people who received either Pfizer-BioNTech or Moderna’s COVID-19 vaccine series, a third dose of the same mRNA vaccine should be used. If the mRNA vaccine product given for the first two doses is not available or is unknown, either mRNA COVID-19 vaccine product may be administered. You do not need to look up the vaccine to confirm.

  • A person should NOT receive more than three total mRNA vaccine doses.
  • Johnson & Johnson vaccines should not be used as the additional dose. ONLY mRNA vaccines (Pfizer and Moderna) can be used for a third additional dose.

Emerging data have demonstrated that immunocompromised people who have low or no protection following two doses of mRNA COVID-19 vaccines may have an improved response after an additional dose of the same vaccine.

Currently a Physicians Order is not required to receive a third dose of MRNA vaccine.  If you qualify, based on the criteria listed, you can make an appointment at
