COVID-19 Vaccines & Boosters

People ages 6 months+ who live, work, or study in Massachusetts should get a COVID-19 vaccine. People ages 5+ should get a booster.

Adults who received a primary vaccine and booster dose of the Johnson & Johnson’s vaccine at least 4 months ago may receive a second booster dose using an mRNA COVID-19 vaccine.


There are free vaccination locations throughout the Commonwealth with appointments available for anyone eligible. Visit VaxFinder.mass.gov to find one near you, or if you need help booking an appointment, call 2-1-1.

The vaccine is safe, free and effective. It’s the best way to protect you and your family. You don't need identification or insurance to get it.

The City of Cambridge and the Cambridge Public Health Department recognize that there are many questions regarding the COVID-19 vaccine. 

The available COVID-19 vaccines are approved and recommended by the FDA and the CDC’s Advisory Committee on Immunization Practices following standard testing and approval processes. By prioritizing resources and efforts, the vaccines were developed quickly and never at the expense of safety. More vaccine safety information is available in this flyer and at mass.gov/COVIDVaccineSafety

Latest updates related to the COVID-19 Vaccine from the City and State.

  • COVID-19 Vaccines for Young Children
    COVID-19 vaccines are safe and effective. Vaccines are recommended even for children who have already had COVID-19, since prior infection does not protect against new variants. COVID-19 infections have caused serious illness, hospitalization, and, in rare instances, death among young healthy children who had no underlying medical conditions. Vaccines can help protect your child.
  • COVID-19 Vaccination Data Reporting Changes
    This week, the Massachusetts Department of Public Health (MDPH) made several changes in the way it reports data related to COVID-19. Importantly, MDPH has worked with the UMASS Donahue Institute to update population estimates for each municipality in the Commonwealth.
  • COVID-19 Vaccine Clinic at Cambridge Rindge and Latin School on Wednesday, July 6
    As part of the Mayor’s Summer Youth Employment Program, the Cambridge Public Health Department is offering a COVID-19 vaccine clinic at Cambridge Rindge and Latin School (CRLS) on Wednesday, July 6. All members of the Cambridge community ages 5 and older are welcome.
