Individuals 16 years of age and older who live, work, or study in Massachusetts can get vaccinated. Use the Massachusetts COVID-19 Vaccine Finder to search for a vaccination location and view appointment availability. Walk-ins are also being welcomed at many locations.

Key things know about the COVID-19 vaccines from the Centers for Disease Control and Prevention (CDC) based on early data:

  • All of the COVID-19 vaccines show promise in reducing severity of disease 

  • It typically takes two weeks after vaccination for the body to build protection (immunity) against the virus that causes COVID-19; you are not fully vaccinated until 2 weeks after the 2nd dose of a two-dose vaccine or two weeks after a one-dose vaccine

  • People who have been fully vaccinated can start to do some things that they had stopped doing because of the pandemic 

What we are still learning:

  • How well vaccines prevent you from spreading the virus that causes COVID-19 to others, even if you do not have symptoms

  • How long COVID-19 vaccines protect people

  • How effective the vaccines are against new variants of the virus that causes COVID-19

The Massachusetts COVID-19 Vaccine Equity Initiative works with the populations and communities hardest hit by COVID-19 to increase awareness and acceptance of the vaccine, access to vaccination locations, and vaccine administration rates. The approach is driven by community needs and is centered on equity, a core pillar of the state’s vaccine distribution plan, and is informed by the state’s  COVID-19 Health Equity Advisory Group and the Vaccine Advisory Group.
