On Monday, a federal judge in St. Louis momentarily prevented the rule in 10 states finding the government had overstepped its authority.
The Tuesday order extended that action and came just hours after a separate federal judge in Kentucky barred the U.S. government from imposing a COVID-19 vaccine mandate on government contractors in Kentucky, Ohio, and Tennessee.
The Biden Administration had ordered that all healthcare and nursing home workers, who work in facilities that take Medicaid and Medicare payments, must get their first jab of the vaccine by December 6 and be fully vaccinated by January 4.
Doughty wrote that he believed the government "do[es] not have the authority to implement" the mandate.
"There is no question that mandating a vaccine to 10.3 million health care workers is something that should be done by Congress, not a government agency," he said. "It is not clear that even an act of Congress mandating a vaccine would be constitutional."
"This matter will ultimately be decided by a higher court than this one. However, it is important to preserve the status quo in this case. The liberty interests of the unvaccinated require nothing less," Doughty wrote.
Doughty also said that while he deemed to limit the scope of the injunction to just the 14 states that filed this particular lawsuit, "there are unvaccinated healthcare workers in other states who also need protection."
"If human nature and history teach anything, it is that civil liberties face grave risks when governments proclaim indefinite states of emergency," the judge added.
Louisiana Attorney General Jeff Landry, who is a Republican, applauded Doughty's decision.
"I applaud Judge Doughty for recognizing that Louisiana is likely to succeed on the merits and for delivering yet another victory for the medical freedom of Americans,' Landry said. 'While Joe Biden villainized our healthcare heroes with his "jab or job" edicts, I will continue to stand up to the President's bully tactics and fight for liberty."
The law restricts the White House from implementing a regulation that new government contracts must include clauses requiring that contractors' employees get vaccinated against the coronavirus to help end the pandemic.
"Can the President use congressionally delegated authority to manage the federal procurement of goods and services to impose vaccines on the employees of federal contractors and subcontractors?" wrote U.S. District Judge Gregory Van Tatenhove in Frankfort, Kentucky. "In all likelihood, the answer to that question is no."
