Below is information about additional doses that are currently approved for people who received the Moderna COVID-19 vaccine and who is eligible to receive them. Please read this information carefully before you make an appointment.

Third Dose for Immunocompromised People

The CDC recommends that people who are moderately to severely immunocompromised receive a third dose of an mRNA COVID-19 vaccine. 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 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.
  • Please talk to your doctor about whether this third dose is appropriate for you.

The third dose should be given at least 28 days after the second dose of either the Pfizer or Moderna vaccine and must be the same vaccine type as your initial two-dose vaccine series. This dose is only for moderately to severely immunocompromised employees who are eligible based on the CDC’s recommendations.

This third dose is not the same as a booster shot. If you received Moderna but are not eligible for the third dose based on the guidance above, do not make an appointment. We expect to learn more about booster shots for Moderna soon and will communicate details as soon as we have them.
