More than 4 million adults in Massachusetts have received at least one COVID-19 vaccine dose after steady progress over the weekend, while most measures of the virus's impact continued to improve ahead of another reopening step starting Monday.
The Massachusetts Department of Public Health reported 72,352 vaccine doses administered and a 48,965 increase in full vaccinations on Saturday, followed by 71,663 doses administered and 42,361 additional full vaccinations on Sunday.
In the state's estimate, 3,811,389 residents have received at least one dose of the Moderna or Pfizer vaccine and 222,819 have received the single-shot Johnson & Johnson vaccine, representing more than 73% of the roughly 5.5 million adults in Massachusetts. Of those, 2,927,088 — about 53% of the adult population — are fully vaccinated.
DPH counted 795 newly confirmed cases and six confirmed deaths on Saturday and 655 cases and three deaths on Sunday.
The department's estimate of active COVID-19 cases dropped to 18,746 in Sunday's report, the fewest since Nov. 5, and the seven-day average positive test rate of 1.24% stands at the lowest level since Oct. 11.
DPH counted 438 patients hospitalized with COVID-19 on Sunday, 21 fewer than on Friday. That figure is still more than three times as high as the all-time low of 140 on Aug. 23.
Changes that took effect Monday allow amusement parks, theme parks and outdoor water parks to reopen operations at 50% capacity, boost capacity for indoor and outdoor venues like stadiums from 12% to 25%, and allow youth and amateur sports tournaments for moderate- and high-risk activities to resume with safety plans in place.
