Ready for your COVID-19 Vaccine?
Need a COVID-19 Test?

The CDC recommends boosters for the following individuals who received the second dose of Pfizer COVID-19 vaccine at least six months ago:

  • All individuals age 65 and older
  • Individuals age 18 – 64 with an underlying medical condition that puts them at risk of severe illness
  • Health care workers and others at risk of exposure to COVID-19 due to their job or living condition

The recommendation applies to those who are fully vaccinated with the Pfizer COVID-19 vaccine only, if it has been more than 6 months since their second dose.

Boosters extend immunity after the initial shots’ potency starts to decrease over time. There are no booster recommendations yet for the Moderna or Johnson & Johnson/Janssen vaccines.

Additionally, third doses of either the Pfizer or Moderna COVID-19 vaccine are recommended for people with compromised immune systems, including cancer or organ transplant patients. Click here for more information on eligibility for third doses.

Boosters and third doses for qualifying individuals can be scheduled at BJC public vaccine clinics and other resources such as public health departments and retail pharmacies.

COVID-19 Vaccines


The safest, most effective path to a more normal life is through a COVID-19 vaccine. It is estimated up to 85% of our community must be vaccinated before we reach the level of “herd immunity” needed to relax infection prevention measures like wearing masks, avoiding crowds and social distancing. Thank you for doing your part by getting vaccinated.

BJC is offering the Pfizer, Moderna and Johnson & Johnson/Janssen vaccines. Supply can vary by location so please check the manufacturer name when you schedule.

  1. Adults age 18 and over may receive the Pfizer, Moderna or Johnson & Johnson/Janssen vaccines.
  2. Children ages 12-17 may receive the Pfizer vaccine. Currently, Pfizer is the only vaccine available to those 12-17 so if you are scheduling a child please make sure to select an appointment for a Pfizer vaccine. Children under 18 must be accompanied to their appointment by a parent or legal guardian.
