A vaccination requirement still stands for millions of health care workers. Whereas, the "Supreme Court has blocked President Biden's vaccine mandate for large employers."

Several large employers are requiring vaccines.

"United [Airlines] CEO says vaccine mandate appears to have ended weekly deaths of employees from Covid."

Wells Fargo, "which had 230,000 employees as of its last annual report, has a mandate that closely resembles the federal vaccine-or-testing requirement."

"Citi’s [Bank] stricter vaccine mandate will still go into effect on Friday. The bank is requiring its 210,000 employees be vaccinated, or else be fired at the end of this month. Head of human resources Sara Wechter said Thursday evening that the company has reached 99% compliance."

"Apparently, there is still a federal rule for federal contractors in place that still requires vaccines. The federal rule covers companies like Boeing, with 141,000 employees, and Honeywell, which has 103,000 employees, American Airlines."
