Ten people in Oklahoma were hospitalized after being injected with insulin instead of a flu shot, local authorities said.
Eight of the patients were residents of Jacquelyn House, a facility that serves intellectually and developmentally disabled people. The two other patients were employees of the facility.
Emergency medical crews arrived at the center on Wednesday after being told that one person was unresponsive after receiving the shot. When they arrived, they found multiple unresponsive people. All 10 of the affected people were taken to the hospital. Several remained hospitalized Thursday because they were administered long-acting insulin. No fatalities were reported. An investigation is currently underway.
