November 17, 2021-- Governor Janet Mills announced today that, effective immediately, all Maine adults age 18 and older are eligible to receive a COVID-19 booster shot, regardless of underlying medical condition. Expanding booster eligibility will protect the health of Maine people, limit transmission of the deadly Delta variant, and preserve our health care system's capacity now overburdened because of a sustained surge of COVID-19 cases. Because of this surge, particularly among unvaccinated individuals, the Maine Center for Disease Control and Prevention has determined that all Maine residents live or work in high-risk settings, justifying the expansion of booster eligibility.
