The Supreme Court has stopped a major push by the Biden administration to boost the nation's COVID-19 vaccination rate, a requirement that employees at large businesses get a vaccine or test regularly and wear a mask on the job. At the same time, the court is allowing the administration to proceed with a vaccine mandate for most health care workers in the U.S. Helix Virtual Medicine offers COVID-19 testing for employers who wish to test their employees. While the mandate has been halted, the company says it still has high demand for businesses using its service. The court's orders Thursday during a spike in coronavirus cases were a mixed bag for the administration. The court's conservative majority concluded the administration overstepped its authority by seeking to impose the Occupational Safety and Health Administration's vaccine-or-test rule on U.S. businesses with at least 100 employees.
