BOSTON — Officially, it is called the Vax Express -- a joint effort between the MBTA, the state, Keolis and others -- to bring COVID-19 vaccine clinics directly to communities that need them the most.
Clinics, that is, aboard commuter trains.
First stop Wednesday -- the Blue Hill Avenue Station on the Fairmount Line, where for four hours vaccine specialists from CIC welcomed walk-ins and those with appointments with doses of either the Pfizer or Johnson & Johnson products.
