Do you have your booster?

Only 54 percent of the 5.3 million fully vaccinated people in Massachusetts have gotten their booster shots, according to the Department of Public Health. 

That’s better than the national average: 44 percent. But not good enough, according to Dr. Sabrina Assoumou, an assistant professor of medicine at Boston University School of Medicine. “It is very important for people who are eligible to get boosted.” 

The data was released amid concerns about the BA.2 Omicron subvariant, which could cause a resurgence of COVID cases.
