State public health officials released updated data on Tuesday tracking the number of fully vaccinated individuals who have tested positive for COVID-19.

Massachusetts had seen 9,969 breakthrough cases as of Aug. 7, according to data released by the state’s Department of Public Health. The total number of breakthrough cases increased by 2,232 from the previous week.

About 4,321,931 people in Massachusetts had been fully vaccinated as of Aug. 7, so the breakthrough infections represent 0.23% of individuals who had gotten inoculated.

According to the state, 445 of those 9,969 cases have resulted in hospitalization, representing 0.01% of all fully vaccinated individuals in the state. The number of breakthrough cases that have resulted in death is now at 106, again representing a small fraction — 0.002% — of all fully vaccinated individuals in the state.

There were 100 breakthrough case deaths by the end of July, and the median age for those who died was 82.5 years old, according to a DPH spokesperson. Of those individuals, 73% were reported to have had underlying conditions that made them vulnerable to severe disease.

By the end of July, there were 395 breakthrough hospitalizations, and 57% of those individuals were reported to have had underlying conditions, according to the state.

“Breakthrough cases in Massachusetts are incredibly low, and those hospitalized or who have died are even lower … The best way to protect yourself and your loved ones is to get vaccinated,” the DPH spokesperson wrote in a statement.

Massachusetts has been seeing a rise in COVID-19 cases and hospitalizations over the last month, driven by the highly contagious Delta variant.
