Enforcement of the federal government mandate requiring the Covid-19 vaccine for all federal employees was delayed again by a decision reached in June by the U.S. Court of Appeals for the 5th Circuit. The administration has been unable to enforce the vaccine requirement since January due to a variety of courtroom battles and rulings. The Court stayed the mandate until the current case is considered which expected to be in mid-September 2022.

As of January 2022, when the halt on enforcement was first ordered, the Biden administration said 98 percent of federal employees were in compliance with the Covid vaccine executive order, including 93 percent vaccinated. Agencies will continue in a holding pattern while the appeals take their course. They are not processing or determining exemption requests for medical or religious reasons, and also cannot make any preparations related to disciplinary actions for noncompliance.
