Massachusetts reported 657 new confirmed coronavirus cases Saturday, while the seven-day average dropped to 544 from 564 the day before.

The Department of Public Health reported that the campaign to vaccinate people administered another 66,675 shots.

The department said Friday it had learned of a “reporting lag from a large laboratory” that had lowered both the number of cases and the number of tests conducted, and the missing tests and cases were added to Saturday’s report.

The new confirmed coronavirus cases brought the state’s total number during the pandemic to 656,344.

The department also reported five new confirmed coronavirus deaths, bringing the state’s total to 17,389.


The DPH said 14,396 people were estimated to have active cases of the potentially deadly virus, and 352 confirmed coronavirus patients were in the hospital.

The DPH also reported that 89,990 more tests had been conducted for coronavirus. The total number of tests administered climbed to more than 22.3 million. New antigen tests had been completed for 10,724 people, bringing that total to 1,270,458.

The DPH reported that the seven-day average rate of positive tests, which is calculated from the total number of tests administered, was at 1.03 percent.

The department said the rate would be 1.68 percent if the effect of college testing programs — in which asymptomatic people can be tested repeatedly in an effort to rapidly identify new cases — is factored out.

The number of new vaccinations brought the total to 7,093,824, state officials reported.

The number of new vaccinations was smaller than on Friday, when 67,558 were reported.

The total number of shots administered amounted to 84.8 percent of the 8,365,380 doses shipped to providers in the state so far, the Department of Public Health said.

The total shots administered included 3,918,540 first shots and 2,944,161 second shots. Those who have gotten their second shot of the currently approved two-dose vaccines are considered fully vaccinated.


The state reported a total of 231,123 people who have received Johnson & Johnson’s one-shot vaccine.

The number of people fully vaccinated — with either two shots of the Moderna or Pfizer vaccines or one shot of the Johnson & Johnson — rose to 3,175,284.

Updates on coronavirus cases, deaths and other metrics will be posted shortly.
