Up to 246 Michigan residents who were “fully vaccinated” against COVID-19 later tested positive for the deadly virus, including three who died, according to a new report.
The group, whose cases were reported between January 1 and March 31, tested positive at least two weeks after receiving the last dose of the inoculation, a health official told the Detroit News.
“Some of these individuals may eventually be excluded from this list because they continue to test positive for a recent infection before being fully vaccinated,” said Lynn Sutfin, a spokeswoman for the state Department of Health and Human Services, in an email Monday. .
“These cases are being further reviewed to determine if they meet other CDC criteria for determining potential breakthrough, including no positive antigen or PCR test less than 45 days prior to positive post-vaccination test. Sutfin said.
“In general, these people have been more likely to be asymptomatic or mildly symptomatic compared to vaccinated people,” he said, adding that hospitalization data was available for 117 of the cases, while 129 were incomplete.
“Of the 117 with hospitalization data entered, 11 were hospitalized, 103 were not hospitalized, and three are reported as unknown,” Sutfin said.
The three people who died were 65 or older, and two “were within three weeks of completion of the vaccination,” he said.
“While the majority of the population develops full immunity within 14 days of completing their vaccine series, a small proportion seem to take longer to generate a complete antibody response. CDC is actively working to better understand the risk characteristics of this group, ”he added.
The recently released data emerged as COVID-19 cases in Michigan, which leads the nation in new cases by population, continue to rise and officials are looking to push the blows forward.
The state surpassed 700,000 cases on Monday, according to the Detroit News.
Last week, Gov. Gretchen Whitmer said she was increasing the state goal from 50,000 injections administered per day to 100,000 per day.
