People age 12 and older who live, work, or study in Massachusetts can get vaccinated and, effective immediately, providers in Massachusetts may begin to administer the Pfizer/BioNTech COVID-19 vaccine to individuals age 12 and older. The COVID-19 vaccine is free and one of the best ways to protect yourself and those around you from getting sick from COVID-19. We encourage everyone to get vaccinated. The CDC currently recommends a booster shot for certain individuals who have received a Pfizer vaccine.


To find a location, we recommend the following:



  • Residents should still go to VaxFinder to find a location near them and plan their vaccination or booster shot. VaxFinder also lists important information like each site’s accessibility options, MBTA Trip Planner and more. Over 500 locations have open availability on VaxFinder.
  • In addition, below are other ways for eligible people to find an available appointment:


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

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

  • Pfizer COVID-19 Vaccine Booster Shot Recommended for Some Groups
    A booster shot is an extra dose of a vaccine that can help 'boost' the immune system to better protect against disease. COVID-19 vaccines work very well to protect against serious illness and death. However, protection against more moderate disease may decrease over time. Recent research shows that a Pfizer COVID-19 booster shot strengthens the immune response in people who had had their second Pfizer shot at least 6 months earlier.
  • CDC Statement on ACIP Booster Recommendations
    CDC Director Rochelle P. Walensky, M.D., M.P.H., endorsed the CDC Advisory Committee on Immunization Practices’ (ACIP) recommendation for a booster shot of the Pfizer-BioNTech COVID-19 vaccine in certain populations and also recommended a booster dose for those in high risk occupational and institutional settings. The Food and Drug Administration’s (FDA) authorization and CDC’s guidance for use are important steps forward as we work to stay ahead of the virus and keep Americans safe.
  • High COVID-19 Vaccination Rates Among University Students and Employees
    The City of Cambridge extends a warm welcome to returning university students and staff after a year and a half of interrupted academic life. COVID-19 vaccines and increased knowledge of measures that help control the spread of the virus will help students have a more traditional residential experience this fall. The City’s three largest academic institutions - Harvard, MIT, and Lesley - report high vaccination rates among their students and employees.
  • FDA Approves First COVID-19 Vaccine
    Today (August 23, 2021), the U.S. Food and Drug Administration approved the first COVID-19 vaccine. The vaccine has been known as the Pfizer-BioNTech COVID-19 Vaccine, and will now be marketed as Comirnaty (koe-mir’-na-tee), for the prevention of COVID-19 disease in individuals 16 years of age and older. The vaccine also continues to be available under emergency use authorization (EUA), including for individuals 12 through 15 years of age and for the administration of a third dose in certain immunocompromised individuals.

Additional information on the COVID-19 Vaccine.

The Commonwealth of Massachusetts has an active inter-agency working group working to ensure an equitable and speedy distribution of COVID-19 vaccine to Massachusetts communities. View the latest vaccine updates in MA, including the vaccine prioritization plan, frequently asked questions, and information from the Centers for Disease Control (CDC).

The Massachusetts Department of Public Health (DPH), Centers for Disease Control and Prevention (CDC), and American Academy of Pediatrics, have put together additional Frequently Asked Questions about the vaccine which can be found as follows:

To help older residents get to their vaccine appointments, the State announced that individuals who accompany someone age 75 or older to get a vaccine at a mass vaccination site may also schedule and receive their own vaccination on the same day. They should go to and schedule two separate appointments at either the same time or adjacent. For the companion appointment, select the option ‘I am accompanying someone who is age 75+ to their vaccination appointment and my appointment is the same day.’ Transportation to vaccination sites is also available for elderly residents through Cambridge-Somerville Elder Services (SCES). For more information about the SCES vaccination transportation program, or to register for a ride, call SCES at 617-628-2601 or email
