In just one week, another 150 vaccinated people tested positive for coronavirus in Massachusetts, according to the latest state data, bringing the total breakthrough cases to nearly 4,000 to date.
The so-called breakthrough cases — cases where fully vaccinated individuals test positive for coronavirus — have so far been rare, but are possible. The numbers account for approximately one in 1,000 vaccinated people in Massachusetts.
As of June 12, there were 3,791 cases of COVID-19 among more than 3.7 million fully vaccinated people in Massachusetts, according to the Department of Public Health. That’s 150 more than the 3,641 breakthrough cases that were reported as of June 5, and 708 more than the 3,083 fully vaccinated people who had tested positive as of May 17.
According to the U.S. Centers for Disease Control and Prevention, a total of 10,262 breakthrough infections were reported throughout the country as of April 30, at which time 101 million people had been vaccinated.
