Nearly 4,000 fully vaccinated people in Massachusetts contracted the Chinese coronavirus, according to the state Department of Public Health.
There were 3,791 coronavirus cases reported as of June 12, according to reports.
“We’re learning that many of the breakthrough infections are asymptomatic or they’re very mild and brief in duration,” Boston University infectious diseases specialist Davidson Hamer said, according to the Boston Herald. “The viral load is not very high.”
Breakthroughs, he continued, are “expected,” but he said, “We need to better understand who’s at risk and whether people who have a breakthrough can transmit the virus to others.”
