All vaccinated adults can now get a booster COVID shot in Mass.

All Massachusetts adults ages 18 and older are now eligible to receive COVID-19 booster shots, provided enough time has passed since their initial vaccine doses, the Baker administration said Thursday.

Previously, Pfizer and Moderna booster eligibility was limited to people 65 and older, younger adults who face increased risks from COVID-19 because of underlying medical conditions or because they work or live in higher-risk environments, and adults who got the Johnson & Johnson single-dose vaccine.

As federal regulators weigh eligibility expansions, some states, including Maine and Vermont, have already opened up eligibility across their adult populations.

The Baker administration said it "encourages COVID-19 boosters for all fully vaccinated individuals 18+."

Adults can get a booster dose from any of the three manufacturers six months after their second Moderna or Pfizer dose or two months after receiving the Johnson & Johnson vaccine. The state's Vaxfinder site provides a list of booster locations. People unable to use the website can call 211 for help.
