Massachusetts on Tuesday reported 3,078 more COVID-19 cases among fully vaccinated people since last week, bringing the total since the beginning of the vaccination campaign to 51,007 cases, or 1.08 percent of all fully vaccinated people.

The Department of Public Health also reported 35 more COVID-19 deaths among fully vaccinated people, bringing the total to 406 deaths among those fully vaccinated. The number of breakthrough deaths represents a tiny fraction of all vaccinated people and underscores the protection the vaccines provide against severe illness and death.

The deaths accounted for 0.009 percent of the 4,711,614 people in Massachusetts who were fully vaccinated, the department said in its weekly update on breakthrough COVID-19 metrics, which included data reported through Saturday.


The department also reported 121 more hospitalizations among fully vaccinated people, for a total of 1,687 hospitalizations. That represents 0.04 percent of all fully vaccinated people.

State officials and public health experts have repeatedly stressed that vaccination greatly reduces hospitalization, severe illness, and death as a result of COVID-19.

As of Tuesday, 4,718,067 people in Massachusetts have been fully vaccinated, according to the department.
