For individuals who received an mRNA vaccine (Pfizer-BioNTech or Moderna)
For individuals who received a Pfizer-BioNTech or Moderna COVID-19 vaccine, the following groups are eligible for a booster shot at 6 months or more after their initial series:
- 65 years and older
- Age 18+ who live in long-term care settings
- Age 18+ who have underlying medical conditions
- Age 18+ who work or live in high-risk settings
For individuals who received a J&J vaccine
For individuals who received a J&J vaccine, booster shots are recommended for those who are 18 and older and who were vaccinated two or more months ago. This means that all individuals who received a J&J vaccine should receive a booster.
Mixing & Matching (heterologous series)
Both the FDA and CDC support individuals to receive a booster dose that is a different vaccine type than they originally received for their primary series if they choose. CDC’s recommendations now allow for this type of mix and match dosing for booster shots.
