This week, federal district courts issued multiple preliminary injunctions temporarily halting the enforcement of two federal vaccine mandates: Executive Order 14042 (EO 14042), which requires certain federal contractors to ensure that their employees are vaccinated, and the interim final rule issued by the Centers for Medicare & Medicaid Services (CMS), which requires staff at health care facilities that participate in Medicare and Medicaid programs to be vaccinated (CMS rule). The current preliminary injunction halting the enforcement of EO 14042 applies only to Kentucky, Ohio and Tennessee. The combination of the preliminary injunctions preventing the enforcement of the CMS rule, however, applies nationwide.
