The number of confirmed coronavirus cases in Massachusetts dropped Friday to 337, but the Department of Public Health cautioned that a reporting problem had likely artificially depressed the number.
The DPH said 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, which the DPH reported was 39,481. The missing tests and cases will be added to Saturday’s report.
The DPH also reported that the state’s vaccination campaign got another 67,558 shots into people’s arms.
The new confirmed coronavirus cases brought the total number in the state during the pandemic to 655,687.
The department also reported 18 new confirmed coronavirus deaths, bringing the state’s total to 17,384.
The state remains in a struggle with the coronavirus more than a year after it arrived. But thanks to vaccinations, millions are now protected and recent coronavirus numbers have been trending downward.
The DPH said 14,884 people were estimated to have active cases of the potentially deadly virus and 376 confirmed coronavirus patients were in the hospital.
The total number of tests administered climbed to more than 22.2 million. New antigen tests were completed for 5,704 people, bringing that total to 1,259,734.
The DPH reported that the seven-day average rate of positive tests, which is calculated from the total number of tests administered, was at 1.14 percent.
The department said the rate would be 1.88 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 administered to 7,027,149.
The number of new vaccinations was greater than on Thursday, when 51,764 were reported.
The total number of shots administered amounted to around 84.3 percent of the 8,331,450 doses shipped to providers in the state so far, the DPH said.
The total shots administered included 3,892,504 first shots and 2,904,744 second shots of the Moderna and Pfizer two-shot vaccines. It also included 229,901 shots of the Johnson & Johnson one-shot vaccine.
The number of people who have received at least a first shot or a Johnson & Johnson shot edged up to 4,122,405.
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 3,134,645.
