In a ruling today, the U.S. Supreme Court allowed a federal mandate requiring healthcare workers at facilities receiving federal money to be vaccinated. The 5-4 decision means a vaccine requirement for workers at all U.S. nursing homes and other federally funded healthcare facilities issued by the Biden administration can proceed. The mandate applies to workers at hospitals and other healthcare facilities that participate in the Medicare and Medicaid programs. It would affect more than 17 million workers, according to the administration. In a separate 6 to 3 vote, the Court blocked the administration from enforcing a vaccine-or-testing mandate for large employers.
