WASHINGTON (AP) — The federal Department of Health and Human Services is requiring employees who provide care for patients to get their COVID-19 shots. Thursday’s order from HHS Secretary Xavier Becerra will affect more than 25,000 clinicians, researchers, contractors, trainees and volunteers with the National Institutes of Health, the Indian Health Service, and the U.S. Public Health Service Commissioned Corps. It applies to employees who regularly interact with patients, or whose duties could put them in contact with patients. Government agencies and private companies are issuing vaccine mandates as the aggressive delta variant sweeps across the country.
