Massachusetts health officials on Tuesday reported more than 4,500 new breakthrough cases over the past week, and 30 more deaths.
In the last week, 4,608 new breakthrough cases -- infections in people who have been vaccinated -- were reported, with 147 more vaccinated people hospitalized, Massachusetts Department of Public Health officials said Tuesday. Their report brings the total number of breakthrough cases to 58,807, and the death toll among people with breakthrough infections to 468.
Both figures remain a tiny percentage of the total number of all people who have been vaccinated -- the equivalent of just 0.04% of vaccinated people have been hospitalized and 1.2% have had confirmed infections. An even smaller percentage has died: 0.01%. 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.

Reports on Mondays, or Tuesdays after holiday weekends, include all the data reported since Friday's update.
