New Guidelines for Immunocompromised people

The CDC recommends an additional dose of COVID-19 vaccine for moderately to severely immunocompromised people. This includes people who have completed a vaccination series with Pfizer-BioNTech or Moderna and 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

Your additional dose must be administered at least 28 days after your vaccination series has been completed. For eligible immunocompromised people, the CDC recommends the same vaccine as previous doses and recipients must be ages 12+ for Pfizer-BioNTech or ages 18+ for Moderna. Johnson & Johnson patients are not eligible for an additional dose at this time. 

People should talk to their healthcare provider about their medical condition, and whether getting an additional dose is appropriate for them. If you are eligible, select the link to schedule an appointment. For more information on the CDC's recommendation, visit

Vaccination schedules may change due to inclement weather, community demand, or vaccine supply. Vaccine type (Pfizer, Moderna, or Johnson & Johnson) depends on availability. For additional locations offering vaccines, please visit:

Moderna and Johnson & Johnson vaccines are currently authorized for ages 18 and older.
