While the court left open the possibility for the U.S. to pursue more targeted mandates, White House officials said there were no immediate plans to seek a redo of the regulation.

“It’s now up to the states and individual employers to put in place vaccination requirements,” said White House press secretary Jen Psaki on Friday.

The United States is already “languishing,” with a 60% vaccination rate, near the bottom of peer nations, said Lawrence Gostin, a public health law expert at Georgetown University.

“The OSHA rule was truly the president’s last best shot at significantly boosting the vaccination rate,” Gostin said. But the court, “in a very highly partisan way, intentionally tried to handcuff the president in doing what he needs to do.’’
