Steps to get your vaccination

Step 1: Preregister for a mass vaccination or regional collaborative location, or find a location and schedule your appointment

Note: An attestation form is no longer required.

There are different ways to find a vaccine appointment:

Massachusetts’ preregistration system makes it easier to request and schedule an appointment. People can preregister for a COVID-19 vaccine appointment at mass vaccination locations and certain regional collaborative locations only. More locations will continue to be added.

Once you sign up for preregistration, you’ll receive weekly status updates. You can opt out at any time if you find an appointment elsewhere. Once an appointment is available, you’ll be contacted with the opportunity to book the appointment and have 24 hours to accept it.

Massachusetts receives a limited supply of COVID-19 vaccine doses from the federal government each week. Due to high demand and very limited supply, it may take several weeks to schedule an appointment or to be notified that an appointment is available.

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 timing by group 4/19/21

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 16 is eligible for the vaccine (vaccines are not yet approved by the federal government for people under the age of 16).
