Important Message About COVID-19 Vaccine Boosters

September 27, 2021

Dear Members of the Yale Community:

The FDA has extended its Emergency Use Authorization (EUA) for the Pfizer-BioNTech COVID-19 vaccine (the Pfizer vaccine) to allow for a single booster dose to be administered to certain groups of individuals who are at least six months past the second doses of their “primary series” vaccinations with the Pfizer vaccine.

The Yale COVID-19 Vaccine Program has relocated to 310 Winchester Avenue, and our scheduling portal is now open for boosters to increase protection against infection with SARS-CoV-2. Individuals who meet the criteria for a booster dose can self-schedule; this generally includes individuals who meet the following criteria and received the second dose of the Pfizer vaccine at least 6 months ago:

  • people 65 years and older;
  • people aged 50–64 years with underlying medical conditions;
  • people aged 18-64 years who are at increased risk for COVID-19 exposure and transmission because of their occupational or institutional work/role.

Appointments for all COVID-19 vaccines including booster doses must be scheduled in advance, walk-ins are not allowed. If you need scheduling assistance, please call the Campus COVID Resource Line (CCRL) at 203-432-6604.

Please note: the CDC has not made recommendations for boosters in individuals who received the Moderna or Johnson & Johnson/Janssen (J&J) vaccines but indicated that the Advisory Committee on Immunization Practices (ACIP) will review relevant information about these vaccines “with the same sense of urgency.” The CDC currently does not recommend that individuals who received these vaccines “mix” vaccine doses by receiving a booster of the Pfizer vaccine. The CDC confirmed that it continues to consider individuals to be “fully vaccinated” two weeks after receiving two doses of the Pfizer or Moderna vaccines or one dose of the J&J vaccine.

The Yale COVID-19 Vaccine Program is also scheduling for a primary series of COVID-19 vaccine, an additional dose of vaccine if you meet criteria for immunocompromised, and booster doses.

We encourage you to schedule your appropriate vaccine now.
