COVID-19 Vaccine Booster Update

October 29, 2021

On October 21, 2021, the Advisory Committee on Immunizations Practices (ACIP) recommended the use of COVID-19 vaccination boosters for both the Moderna COVID-19 vaccine and Janssen COVID19 vaccine (Johnson and Johnson) under the current emergency use authorization. Pfizer-BioNTech COVID-19 vaccine boosters were previously recommended by ACIP on September 24, 2021.

  • Pfizer-BioNTech and Moderna COVID-19 booster vaccines are currently recommended for individuals 18 years of age and older who have completed their initial COVID-19 vaccination series, at least 6 months have passed since the completion of their second dose and they meet one of the following criteria:

    o 65 years or older
    o Reside in a long-term care facility
    o 18-64 years of age with underlying medical condition(s)
    o 18-64 years of age with increased risk for COVID-19 exposure and transmission because of occupational or institutional setting
  • Janssen (Johnson and Johnson) COVID-19 booster vaccines are currently recommended for individuals who have received their initial COVID-19 vaccination and at least two months have passed since their initial dose.

There are now booster recommendations for all three available COVID-19 vaccines in the United States. Eligible individuals may choose which vaccine they receive as a booster dose, when available. Some individuals may have a preference for the vaccine type that they originally received, while others may prefer to get a different booster. The Center for Disease Control and Prevention’s recommendations now allow for this type of mix and match dosing for booster shots of COVID-19 vaccine.
