What is a booster?

Do I need a booster?

Staying up to date on vaccines, including boosters, is the most effective way to prevent serious illness, hospitalization, and death from COVID-19. While vaccine protection decreases over time, boosters restimulate the immune system and increase vaccine efficacy again. Boosters are an important defense, even if you’ve already had COVID.

What are the updated boosters that were just approved? 

The new COVID-19 booster vaccines from Moderna and Pfizer are updated versions of the original vaccines. These updated boosters were recently authorized by the FDA and recommended by the CDC. 

Who should get the new booster?    

Anyone age 12 or older who completed a primary COVID-19 vaccination series or received a booster dose at least two months ago should get the updated booster as soon as possible. Individuals without access to the internet or who are unable to schedule their appointment online can call the COVID-19 Vaccine Resource Line toll free 2-1-1 or 877-211-6277 for assistance with setting up an appointment. 

When and where can I get the updated booster?   

Updated boosters will be available in Massachusetts the week of September 5, 2022. You can get boosters where you received previous vaccines, including doctor’s offices, hospitals, pharmacies, and community health clinics.  

Am I fully vaccinated without a booster?

You are fully vaccinated without a booster if it has been at least 2 weeks since you got your first J&J shot or your second Pfizer, Moderna or Novavax shot, according to the CDC. 

Am I considered “up to date” without a booster?

As with vaccines for other diseases, people are best protected against infection with the virus that causes COVID-19 when they stay up to date with vaccinations.

A person is up to date with their COVID-19 vaccination if they have received all doses in the primary series and all boosters recommended, when eligible. 

Is the booster free?

Yes, the booster is free. You do not need to pay, have ID, or have health insurance to get a booster.

If I need a booster shot, does that mean that the vaccines aren’t working?

No. COVID-19 vaccines are working well to prevent severe illness, hospitalization, and death, even against the widely circulating variants. However, public health experts are starting to see reduced protection, especially among certain populations, against mild and moderate disease.

People who are moderately or severely immunocompromised have specific COVID-19 vaccine recommendations, including recommendations for a booster. Learn more about COVID-19 vaccine recommendations for people who are moderately or severely immunocompromised.
