SIOUX FALLS, S.D. (AP) — Sanford Health has closed its mass vaccination clinic on its Medical Center campus in Sioux Falls. The health care system opened the clinic in the Sanford Imaginetics building in December and has served more than 102,000 patients. Terri Carlson, executive director at Sanford Health says Sanford still offers the vaccines at its primary care facilities in the Sioux Falls area. Carlson says it’s rewarding to see people being able to start living their lives again and watch people getting back together.
