The Baker-Polito Administration has announced the dates that all remaining MA residents and certain worker groups will be eligible for a vaccine.

All residents can preregister to book an appointment at a mass vaccination site at mass.gov/COVIDVaccine.

Appointments will be offered based on eligibility and available appointments nearby. It is expected that more sites will come online as part of the preregistration process in April.

Timeline for remaining groups:

• March 22nd: Residents 60+ and certain workers
• April 5th: Residents 55+ and residents with one certain medical condition
• April 19th: General public ages 16 years of age and older

The full timeline is available at mass.gov/COVIDVaccinePhases.

The Administration has received assurances from the federal government that an increased vaccine supply will be available to states soon.

Depending on supply, it could take weeks for people to be notified that an appointment is available at a mass vaccination site.
