Massachusetts' COVID-19 vaccination phases

The Massachusetts state COVID-19 vaccination attestation form is no longer required. However, your vaccination locations may ask you to sign an attestation or a consent form. 

Learn more about the groups in each phase of the COVID-19 vaccine distribution timeline.

Booster information

Everyone ages 5 years and older should get all COVID-19 primary series doses, plus the most recent booster dose recommended for them. 

• Children ages 5 through 11 (who received Pfizer primary series) are recommended to get 1 monovalent Pfizer booster dose  

• Individuals age 12 or older who completed a primary COVID-19 vaccination series or received a booster dose at least two months ago should get the updated (bivalent) booster as soon as possible.  

You can mix and match vaccines. Your booster does not need to be the same vaccine brand as your original COVID-19 vaccination, as long as it is an age appropriate vaccine.

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.

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. 

Phase 4 began Nov. 3, with children ages 5-11 eligible for the vaccine.

Phase 5 began June 20, with children ages 6 months to 4 years old eligible for the vaccine.
