Massachusetts health officials on Tuesday reported nearly 4,000 new breakthrough cases over the past week, and 32 more deaths.
Also Tuesday, the death toll from COVID in Massachusetts topped 18,000.
In the last week, 3,919 new breakthrough cases -- infections in people who have been vaccinated -- were reported, with 61 more vaccinated people hospitalized, Massachusetts Department of Public Health officials said Tuesday. That brings the totals to 27,777 cases and 194 deaths in people with breakthrough infections.
Both figures remain a tiny percentage of the total number of all people who have been vaccinated -- just 0.02% of vaccinated people are hospitalized, and 0.61% have been infected. An even smaller percentage has died: 0.004%. 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.
