Sept 24, 2021 – Based on recommendations from the Centers for Disease Control and Prevention (CDC) and the U.S. Food and Drug Administration (FDA), Johns Hopkins Medicine will offer the Pfizer-BioNTech COVID-19 vaccine booster to eligible patients starting on Tuesday, Sept. 28. Eligible patients are those who received their second dose of the Pfizer-BioNTech COVID-19 vaccine at least six months ago and meet at least one of the below criteria:

  • Are age 65 or older
  • Live in a long-term care facility
  • Are age 18 or older and have an underlying medical condition that could put them at higher risk of severe COVID-19. Eligible medical conditions include, but are not limited to:
    • Cancer
    • Cerebrovascular disease, such as stroke
    • Obesity
    • Chronic obstructive pulmonary disease
    • Diabetes mellitus, type 1 and 2
    • Heart condition, such as heart failure, coronary arteries disease, or cardiomyopathies
    • Chronic kidney disease
    • Pregnancy and recent pregnancy
    • Current or former smoker
  • Are age 18 or older and work in a location that puts them at high risk of exposure to COVID-19. This includes:
    • Essential workers, such as health care workers, teachers, day-care staff, and first responders
    • Caregivers of an immunocompromised individual
    • Individuals who live in a congregate living setting, such as a homeless shelter, prison, or assisted living facility

The amended FDA authorization and updated CDC recommendation apply only to the Pfizer-BioNTech COVID-19 vaccine.

Johns Hopkins Medicine has limited booster appointments. Eligible individuals should use all available resources to get a booster, including retail pharmacies and local and state resourcesRead more about scheduling an appointment.

Based on earlier guidance from the CDC and FDA, individuals who received either the Pfizer-BioNTech or the Moderna COVID-19 vaccines and have a medical condition associated with immunosuppression are eligible to receive a third dose of the same vaccine brand they originally received.

The FDA has not yet authorized a booster for those who received the Janssen/Johnson & Johnson vaccine or those who received the Moderna vaccine and who are not immunosuppressed.

We encourage all eligible individuals to receive an initial COVID-19 vaccination if they have not already done so. Eligible individuals can read more about how to get a COVID-19 vaccination from local and state sites.
