Massachusetts plans on closing four of its seven mass vaccination sites by the end of June in favor of a more targeted approach to reach the roughly 30 percent of the state’s eligible population that has not yet received at least one dose of a coronavirus vaccine.

Gov. Charlie Baker said Monday the state will instead send more doses to 22 smaller regional sites, expand mobile vaccination efforts, and bring vaccine clinics to senior centers, YMCAs, houses of worship and other community sites.

The vaccination sites to close are the ones at Gillette Stadium, the Doubletree Hotel in Danvers, the Natick Mall, and the Hynes Convention Center in Boston.
