New York City can proceed with vaccine mandate for educators and staff, judges ruled.

New York City’s vaccine mandate for nearly all adults working in its public schools can proceed as scheduled, a federal appeals panel ruled on Monday, reversing a decision made over the weekend that paused enforcement of the mandate until later this week at the earliest.

Mayor Bill de Blasio had originally ordered well over 150,000 educators and staff in the nation’s largest school system to receive at least one dose of a Covid-19 vaccine by tonight at midnight. That deadline was put on hold late Friday by a judge of the U.S. Court of Appeals for the Second Circuit. The three-judge panel was scheduled to take up the issue on Wednesday, but it appears to have ruled early.

It’s not yet clear if the city will decide to implement the mandate tonight at midnight as originally scheduled or wait until later in the week.
