In the last week, 2,509 new breakthrough cases -- infections in people who have been vaccinated -- were reported, with 120 more vaccinated people hospitalized over the period, Massachusetts Department of Public Health officials said Tuesday.

The new report brings the total number of breakthrough cases to 456,391 and the death toll among people with breakthrough infections to 2,201.

It's important to note the death toll has been revised from the previous week's, which was 2,484. This is based on an update to the definition the state is now using for COVID-19 associated deaths. The state unveiled that newly revised death toll in the data released Monday. There were two new deaths among people in breakthrough infections in the last week.

These figures remain a tiny percentage of the total number of all people who have been vaccinated.

The equivalent of just 0.14% of vaccinated people have been hospitalized with COVID and 8.6% have had confirmed infections. An even smaller percentage has died: 0.04%. 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. In December, Massachusetts Department of Public Health officials released a study that found that 97% of breakthrough cases in the state did not become severely ill and rarely led to deaths, especially among young people.

Massachusetts' COVID metrics, tracked on the Department of Public Health's interactive coronavirus dashboard, have declined since the omicron surge and appear to have leveled out.

Experts have said that case count reporting may be a less accurate indicator during the omicron surge, given the difficulties in getting tested and widespread use of rapid tests that go unreported. Officials also warn that health care systems are still under great pressure from the influx of COVID-19 patients and related staffing shortages.

More than 14 million vaccine doses have now been administered in Massachusetts. That includes more than 5.8 million first doses of either Pfizer or Moderna vaccines, 4.9 million second shots, and over 341,000 Johnson & Johnson one-dose shots. Over 2.8 million booster shots have been administered.

Health officials on Tuesday reported that a total of 5,307,266 Massachusetts residents have been fully vaccinated.
