Pfizer booster appointments available at Columbia Greene Community College
The Columbia County Department of Health is holding the following booster POD for Pfizer vaccine recipients.  Please note that the POD date below is only for individuals who received the full series of Pfizer vaccine and are at least 6 months out from their second dose. You will need to bring a photo ID along with your COVID-19 Vaccination Record Card with you to the booster clinic. Pre-registration is required.

Third Dose/Additional Dose for Immunocompromised

The New York State Department of Health has authorized a third COVID-19 vaccine dose 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.

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.

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.

On September 24, 2021, the CDC authorized COVID-19 vaccine booster doses of the Pfizer vaccine ONLY.  The CDC recommendations are as follows:

  • People 65 years and older and residents of long-term care settings should receive a booster shot of Pfizer vaccine at least 6 months after their primary series of Pfizer,
  • People aged 50-64 years with underlying medical conditions should receive a booster shot of Pfizer vaccine at least 6 months after their primary series of Pfizer,
  • People aged 18-49 years with underlying medical conditions may receive a booster shot of Pfizer vaccine at least 6 months after their primary series of Pfizer, based on their individual benefits and risks, and
  • People aged 18-64 years who are at increased risk for COVID-19 exposure and transmission because of occupational or institutional setting may receive a booster shot of Pfizer at least 6 months after their Pfizer primary series, based on their individual benefits and risks.

Individual benefits and risks are best assessed by an individual’s doctor or medical team.

Currently there is insufficient data to support the use of a booster COVID-19 vaccine dose after an initial two-dose series of Moderna or single-dose Janssen/Johnson & Johnson vaccination.
