STATEHOUSE ROUNDUP: Achievement unlocked Recap and analysis of the week in state government Vaccinate 70 percent of the adult population with at least one dose by July 4? No sweat. Already done. What's next? President Joe Biden set a new vaccination goal for the country last week as Americans seek their independence from the COVID-19 pandemic, but with Massachusetts already there, what's next is a new, more targeted phase in the state's vaccine campaign. Gov. Charlie Baker announced that he would begin to phase out mass vaccinations sites, with four of the seven slated to close by the end of the June. As Gillette Stadium, the Danvers DoubleTree Hotel, the Hynes Convention Center and the Natick Mall end their runs as vaccine centers, the administration plans to divert more of its vaccine supply to regional sites, mobile clinics and primary care doctors.
