What’s the status of the COVID-19 vaccine mandate in the U.S.? It’s on hold indefinitely because of legal challenges, but employers can still require the shots.

But soon after the rule was issued by the U.S. Occupational Safety and Health Administration, it faced multiple legal challenges from businesses, conservative groups and Republican attorneys general that said the agency doesn’t have the authority to mandate vaccines.

On Nov. 6, a federal appeals court in New Orleans put the rule on hold, saying it was "a one-size fits-all sledgehammer" that was too broad.

In a court filing, lawyers for the Biden administration said the mandate was needed to reduce transmission of the virus in workplaces. It asked that it be allowed to move ahead with the rule.
