COVID-19 Vaccine

Pfizer Booster Shots Now Available

The Maryland Department of Health has approved the administration of a third “booster” dose of Pfizer vaccine for individuals who meet specific criteria. Booster doses are different than an “additional dose” for immunocompromised individuals.


You are only eligible to receive Pfizer booster dose if:

  1. Both of your previous shots were Pfizer and your second dose was at least 6 months ago; AND

  2. One of the following is true:

    • You are 65 years or older;

    • You live in a long-term care setting;

    • You are age 18-64 and at increased risk for COVID-19 exposure and transmission because of your work or institutional setting (ex. Medical professionals, correctional officers)

    • You are 18-64 with a serious underlying medical condition (see form for complete list of qualifying conditions).


To receive your booster dose, you may register for an appointment at any Pfizer clinic offered by the Health Department. When you get to the fourth page of the registration, select that this is your third shot.


You will be required to fill out the Self-Attestation of Eligibility Form for Pfizer Booster Vaccination prior to receiving your shot. You may complete the form at home and bring it with you, or you can complete it at the vaccination site. Vaccine Center staff will access your vaccine record to confirm that you received Pfizer and that your second dose was at least six months ago prior to authorizing the booster shot.
