STATE HOUSE NEWS SERVICE
IN THE WEEK between August 7 and August 14, almost 2,700 fully vaccinated people became infected with COVID-19 in Massachusetts, the Department of Public Health said Tuesday.
There have been a cumulative 12,641 breakthrough infections reported out of 4,415,936 fully vaccinated people as of Aug. 14, DPH said Tuesday — meaning that 0.29 percent of all fully vaccinated people have subsequently been infected with the coronavirus, up from 0.23 percent of the immunized population a week ago and 0.18 percent two weeks ago.
In the week from August 7 to August 14, DPH counted 2,672 new breakthrough infections, about a 20 percent increase over the 2,232 breakthrough infections reported the previous week.
As it did last week, DPH cautioned Tuesday that there are probably more breakthrough infections and hospitalizations among fully vaccinated people than it counts and can report.
