COVID-19 Booster Vaccine Information

Brown Medicine follows RI Dept. of Health (RIDOH) and CDC guidance for booster shots.


At this time, booster shots are available for persons who are not immunocompromised and initially vaccinated with the Pfizer-BioNTech, Moderna or Johnson and Johnson (Jansen) vaccine; as well as for moderate to severely immunocompromised persons who have already received two doses of the Pfizer or Moderna vaccine more than 28 days ago. It is safe to mix or match booster vaccines to the original type. We recommend all our patients receive the booster doses, if in the eligible categories.

Moderna and Pfizer-BioNTech:
Anyone in certain risk groups (see below) who completed vaccination 6 or more months ago may receive a booster dose.

Johnson & Johnson:
A single booster dose of any of the three COVID-19 vaccines may be administered two months or more after completion of the single-dose primary regimen to anyone age 18 or older. Brown Medicine suggests use of the Moderna or Pfizer-BioNTech vaccine as a booster, unless the Johnson and Johnson vaccine was specifically chosen for a medical reason (and not for the one-shot convenience). However, using the J+J vaccine as a booster is also reasonable.
