The U.S. Department of Labor’s Occupational Safety and Health Administration on Tuesday said it is withdrawing the vaccination and testing emergency temporary standard that it issued on Nov. 5.

The Biden administration is withdrawing its Covid-19 vaccination and testing rules for private businesses with 100 or more employees effective Wednesday following the U.S. Supreme Court’s Jan. 13 ruling that blocked the regulations.

The U.S. Department of Labor’s Occupational Safety and Health Administration on Tuesday said it is withdrawing the vaccination and testing emergency temporary standard that it issued on Nov. 5 to protect unvaccinated employees of large businesses with 100 or more employees from workplace exposure to coronavirus, according to a department statement.

Despite withdrawing its Covid-19 vaccination and testing rules, OSHA is not withdrawing the emergency temporary standard as a proposed rule, it said in the statement. The agency it will continue working to finalize a permanent Covid-19 healthcare standard.

“I am disappointed in the court’s decision, which is a major setback to the health and safety of workers across the country,” U.S. Secretary of Labor Marty Walsh said in a statement on Jan. 13 after the Supreme Court ruling. “OSHA stands by the Vaccination and Testing Emergency Temporary Standard as the best way to protect the nation’s workforce from a deadly virus that is infecting more than 750,000 Americans each day and has taken the lives of nearly a million Americans.”

The Supreme Court ruling removed the Biden administration’s authority to regulate vaccinations and testing for large companies, but businesses still have the option of implementing their own rules and many have them in place.
