Phased vaccine distribution plan

Massachusetts’ COVID-19 vaccination plan was guided by the Commonwealth’s COVID-19 Vaccine Advisory Group, a diverse group launched in October consisting of medical professionals, public health experts, elected officials, community leaders, and infectious disease specialists. The plan consists of 3 phases, which reflect several priorities: protecting our most vulnerable, maintaining health care system capacity, and addressing inequities in health care access and COVID-19 burden.

COVID-19 Phases Vaccination Timing by Group

Phase 1 of the plan began in December, and prioritized health care workers, first responders, and vulnerable populations like those in congregate care settings and residents and staff of long-term care facilities.

Massachusetts moved to Phase 2 in February, and the plan continued to focus on vaccinating the oldest and most vulnerable, supporting the Commonwealth’s nation-leading success in vaccinating these populations. Phase 2 also included workers in certain categories and people with certain medical conditions.

As of April 19, Massachusetts has entered Phase 3 of the vaccine distribution plan. Everyone over the age of 12 is eligible for the vaccine.
