Boston Globe – Stung by criticism it was moving too slowly, the Baker administration has overhauled its approach to delivering COVID-19 vaccines in just three weeks, increasingly relying on a network of massive facilities equipped to give more shots quickly as it expands the pool of eligible residents.

The rise of mass vaccination sites such as Boston’s Fenway Park and Gillette Stadium in Foxborough has helped to rapidly boost the state’s standing in national vaccine distribution. Its ranking shot up to 17th in per capita doses administered, according to the latest federal data. As recently as Feb. 1, Massachusetts ranked 34th among states.

With growing capacity to give shots assembly-line style, emboldened state officials doubled the number of residents who qualify for a vaccine literally overnight last week, adding almost 1 million aged 65 to 74, living in low-income senior housing, or suffering from two or more medical conditions.
