Flu Shot: It's That Time Again

Although Massachusetts has historically ranked high in its overall immunization rates — 50 percent of all residents received vaccines in 2015-16 flu season — that percentage dropped from 55 percent the year before. The lowest rates of vaccination are in residents 18-49 — 40 percent for the 2015-16 season, but vaccine rates for all age groups (except young children) dropped slightly as well.
