With widespread community transmission, breakthrough cases of COVID-19 continue to show up, as experts have predicted, but they’re much less likely to lead to hospitalization and death. So far only about 1.2% of vaccinated people have tested positive for COVID-19.
The state released updated data Tuesday on the number of COVID-19 cases, hospitalizations, and deaths among vaccinated individuals in Massachusetts. There have been a total of 58,807 breakthrough cases of COVID-19 as of Nov. 6, an increase of 4,608 from Oct. 30. Between Oct. 23 and 30, 3,192 breakthrough cases were reported, so about 1,400 more breakthrough cases were reported this week, a massive jump from last week, but case counts also increased.
