The health department on Tuesday announced three Moderna vaccine booster clinics: 11 a.m. to 3 p.m. Thursday; 4 to 8 p.m. Monday; and 11 a.m. to 3 p.m. Dec. 16.

All are by appointment only for people 18 and older who live or work in Cambridge. The while-supplies-last clinics are inside the CambridgeSide mall, 100 CambridgeSide Place, East Cambridge, on the third floor. (Use the escalator near the Cheesecake Factory on the CambridgeSide Place end of the mall, or take the elevator. Free parking is available in the lower level of the parking garage; the entrance is on CambridgeSide Place.)

Eesidents can mix and match vaccines and do not need to get the same brand for their booster as they did for their original vaccination.
