Free flu shots are available this season to Sharon residents age 5 and older through the Sharon Health Department. Influenza vaccines are administered at the department’s office, at 90 South Main St., from 3 to 5 p.m. Tuesdays and 9 to 10:30 a.m. Wednesdays, Thursdays, and Fridays. The department asks those seeking the vaccine to bring all their health insurance cards and wear short sleeves. Copies of insurance cards are acceptable. Residents can speed the process by printing and filling out the necessary paperwork from the town’s website in advance.
