Guidance on COVID-19 Boosters

November 29, 2021

All individuals 18+ are now eligible for a COVID-19 booster in Massachusetts.

The Massachusetts Department of Public Health recommends booster shots for all three COVID-19 vaccines available in the United States.

If You Received Moderna or Pfizer

Adults age 18+ may get a booster 6 months after the second dose of the Moderna or Pfizer-BioNTech COVID-19 vaccines. You may choose any vaccine brand for your booster.

If You Received Johnson & Johnson (Janssen)

Adults age 18+ may get a booster 2 months after the first dose of Johnson & Johnson COVID-19 vaccine. We recommend that your booster be Moderna or Pfizer. 

Getting a COVID-19 Booster

For more information and FAQs about the guidance, visit the CDC website.

As a reminder, if you are moderately to severely immunocompromised, you may get a third dose of vaccine 28 days after receiving your second dose of the Moderna or Pfizer COVID-19 vaccine (no need to wait 6 months).

Scheduling Your Booster Shot

If you are eligible for a booster shot, visit or to find a location where you can receive it in Massachusetts, including commercial pharmacies. Booster shots remain available at no cost to you. HUHS is focusing on providing vaccine to patients who still need their first or second dose, so please seek booster shots elsewhere at this time.

In-home vaccinations are available for home-bound persons who are unable to get to a vaccine location.  In-home vaccines can be arranged by calling In-Home Vaccination Central Intake Line at (833) 983-0485 Monday through Friday from 9 a.m. to 5 p.m.
