COVID-19 Vaccine Updates

Booster shot update

The U.S. Food and Drug Administration and the Centers for Disease Control and Prevention (CDC) now recommend a booster dose for all children ages 5 to 11 at least 5 months after the completion of the primary vaccine series.

  • For children who are moderately or severely immunocompromised, the recommended primary series is 3 doses of an mRNA vaccine followed by a booster (4th dose).

A booster dose creates increased antibody levels, a stronger immune response against new variants and greater protection against infection and severe illness from COVID-19.

People who are 12 years of age or older and moderately to severely immunocompromised may choose to receive a second booster dose with a mRNA vaccine if it has been at least 4 months since the first booster. Please note that those 5 to 17 years of age can only receive the Pfizer vaccine.

For more information, please refer to our Booster Shots page.

Vaccine clinics update

Starting May 23, 2022, the Dartmouth Hitchcock Medical Center drive-thru in the Colburn Hill parking lot will be offering COVID-19 vaccines for people who are 12 years of age and older, Monday through Friday. For more information, please visit our COVID-19 Vaccine Clinics page.


While statewide mask mandates have been lifted, please note that masks are still required in all of our healthcare facilities until further notice. Masks are the most effective way to keep our patients and employees safe.
