Michigan public health officials say 246 people tested positive for the coronavirus two weeks or more after becoming fully vaccinated – and three have died. Lynn Sutfin, spokeswoman for the state health department, told USA TODAY in an email that the positive tests represent a small fraction of 1% of the 1.7 million vaccinated across the state. Two of the three deaths occurred within three weeks of completing the vaccine, she said. All three were 65 or older.
“While the majority of the population develops full immunity within 14 days of completion of their vaccine series, a small proportion appear to take longer to mount a full antibody response,” Sutfin wrote.
