An audio version of this story. Many Oklahoma health care facilities run by either or both the Indian Health Service and individual tribes have begun greatly expanding eligibility for COVID-19 vaccine appointments, including for non-Native household members and caregivers of tribal citizens. "All Oklahoma City Area federal facilities have vaccine appointments available for eligible American Indians and Alaskan Natives, as well as their non-Native household members and caregivers, who are 16 years of age and older," the IHS Oklahoma City Area, which covers all of Oklahoma and Kansas, announced Thursday. Those facilities include the Pawnee Indian Health Service, Wewoka Indian Health Service and Claremore Indian Hospital, among others. (Wewoka and Claremore have set 18 as their minimum age.)
