Medical groups representing millions of doctors, nurses, pharmacists and other health workers called for mandatory vaccinations of all U.S. health personnel against the coronavirus, framing the move as a moral imperative as new infections mount sharply. “We call for all health care and long-term care employers to require their employees to be vaccinated against COVID-19,” the American Medical Association, the American Nurses Association and 55 other groups wrote in a joint statement. “The health and safety of U.S. workers, families, communities and the nation depends on it.”
