Massachusetts health officials on Tuesday reported nearly 3,500 new breakthrough cases over the past week, and 26 more deaths. The number of breakthrough infections is equivalent to just over 1% of all fully vaccinated people in the state.
In the last week, 3,431 new breakthrough cases -- infections in people who have been vaccinated -- were reported, with 138 more vaccinated people hospitalized, Massachusetts Department of Public Health officials said Tuesday. Their report brings the total number of breakthrough cases to 47,929, and the death toll among people with breakthrough infections to 371.
Both figures remain a tiny percentage of the total number of all people who have been vaccinated -- the equivalent of just 0.03% of vaccinated people have been hospitalized, and 1.02% have had confirmed infections (the latter figure up from 0.95% last week). An even smaller percentage has died: 0.008%. 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.

Massachusetts' COVID metrics, tracked on the Department of Public Health's interactive coronavirus dashboard, dashboard, are far lower than they were in spring, and while all of the major ones have risen from their lowest points, some have dipped in recent weeks. Reports on Mondays, or Tuesdays after holiday weekends, include all the data reported since Friday's update.
