Third Dose for Immunocompromised

The New York State Department of Health has authorized a third COVID-19 vaccine dose only for New Yorkers with moderately or severely compromised immune systems. (Please note: this is not the same as a booster dose. See below for information on booster doses.)

This follows the Centers for Disease Control and Prevention (CDC) recommendation on August 14, 2021.

Eligible New Yorkers can receive their third dose 28 days after completion of their two-dose Pfizer or Moderna vaccine series.

The CDC is currently recommending that moderately to severely immunocompromised people receive an additional dose, including people who have:

  • Been receiving active cancer treatment for tumors or cancers of the blood;
  • Received an organ transplant and are taking medications 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, cancer chemotherapy that causes severe immunosuppression, or other medications that may suppress your immune response.

The Emergency Use Authorization (EUA) amendment for an additional dose is not intended for persons with chronic conditions such as diabetes or heart disease, for which there might be mild associated immunosuppression, nor for residents of long-term care facilities who do not otherwise meet the moderate to severe immunocompromised criteria.

Booster Doses

A booster dose is a dose of vaccine administered when the initial sufficient immune response to a primary vaccine series is likely to have waned over time.

At this time, the need for and timing of a COVID-19 booster dose have not been yet established, although the U.S. Department of Health and Human Services (HHS) announced a plan to begin offering COVID-19 vaccine booster shots this fall, contingent on review and approval by the FDA and the Advisory Committee on Immunization Practices.

CDC’s independent advisory committee, the Advisory Committee on Immunization Practices (ACIP), will continue to meet and discuss data on the evolution of the pandemic and the use of COVID-19 vaccines. ACIP will make further recommendations on the use of boosters for the public after a thorough review of the evidence.


Important Information Regarding 3rd Dose COVID-19 mRNA Vaccine:

CCDOH has limited availability of vaccine for third doses. Third dose vaccines are by appointment only and are limited to moderately to severely immunocompromised individuals who have any of the following conditions:
                        -Active treatment for solid tumor and hematologic malignancies
                        -Receipt of solid-organ transplant and taking immunosuppressive therapy
                        -Receipt of CAR-T-cell or hematopoietic stem cell transplant (within 2 years of                                                   transplantation or taking immunosuppression therapy)
                        -Moderate or severe primary immunodeficiency (e.g., DiGeorge syndrome, Wiskott-Aldrich                                 syndrome)
                         -Advanced or untreated HIV infection
                         -Active treatment with high-dose corticosteroids (i.e., ≥20mg prednisone or equivalent per                                day), alkylating agents, antimetabolites, transplant-related immunosuppressive drugs,                                     cancer chemotherapeutic agents classified as severely immunosuppressive, tumor-necrosis                            (TNF) blockers, and other biologic agents that are immunosuppressive or immunomodulatory.

If you are unsure if your condition falls into one of the above categories, please talk to your physician prior to calling for an appointment to determine if a third dose is appropriate for you. You will be required to sign an attestation stating that you fall into one of the categories listed above at the time of your appointment.
