The US Department of Health & Human Services is appealing a federal court's decision to temporarily block the start of its vaccination mandate for healthcare workers, Becker’s Hospital Review reported. A US district judge in Louisiana granted a preliminary injunction Nov. 30, halting the vaccination rule for healthcare workers until legal challenges are resolved. HHS Secretary Xavier Becerra and other defendants filed an appeal Dec. 1, which will be heard by the US Court of Appeals for the 5th Circuit.
