A new initiative to help increase access to the COVID-19 vaccine, particularly in communities with low vaccination rates, is hitting the rails.

The Vax Express, run by CIC Health, will take over an MBTA Commuter Rail train creating a rolling vaccination site that will make stops at stations in disproportionately impacted communities with low vaccination rates.

“The Commonwealth continues to lead the nation in vaccinating our residents, and our goal remains getting every person who wants a vaccine a shot,” said Gov. Charlie Baker. “As we get closer to our goal of vaccinating over 4 million residents, we are increasing targeted, community-based clinics to reach remaining populations.”

About 80% of Massachusetts adults have received at least one dose and more than 3.9 million residents are fully vaccinated.

From June 16 to 20, the Vax Express will make stops at stations in Worcester, Lowell, Lawrence, Fitchburg, and in Boston in Mattapan, North Station and South Station. Vaccinations will take place at these local stations aboard the train, which will be staffed by CIC Health partner Cataldo Ambulance.

The public can walk up without an appointment or book an appointment in advance.

The Vax Express will offer the two-dose Pfizer vaccine for ages 12 and up and the single-dose Johnson & Johnson vaccine for ages 18 and up.
