Massachusetts health officials on Tuesday reported more than 3,700 new breakthrough cases over the past week and 13 more deaths.
In the last week, 3,074 new breakthrough cases -- infections in people who have been vaccinated -- were reported, with 80 more people hospitalized, Massachusetts Department of Public Health officials said Tuesday. That brings the total to 19,443 cases and 144 deaths in people with breakthrough infections.
Both figures remain a tiny percentage of the total number of all people who have been vaccinated -- just 0.01% of vaccinated people are hospitalized, and 0.43% have been infected. An even smaller percentage has died: 0.003%. The report also doesn't indicate how many of the breakthrough cases are in people with underlying conditions, though it also notes that "may be undercounted due to discrepancies" in records.
While vaccinated people are getting COVID-19, the virus' effects are severely blunted in them, and breakthrough cases rarely lead to hospitalizations or deaths. That's why public health officials worldwide continue to stress the importance of vaccination.
