WASHINGTON (TND) — Monday was the original deadline for the first phase of the Biden administration's vaccine mandate for private employers, but that measure remains blocked until federal judges rule on challenges from 27 states.

In the meantime, some cities are taking mandates into their own hands.

New York City Mayor Bill de Blasio announced a first-of-its-kind mandate Monday that would require employees at private companies to get vaccinated by Dec. 27. The city is also expanding its indoor vaccine mandate to children ages 5 and up.

Starting next Tuesday, people will have to show proof of at least one shot to get into restaurants, movie theaters and other indoor spaces.

There was also a victory for vaccine mandates in California Monday. A federal court sided with the San Diego Unified School District, allowing its mandate to remain in place. It requires staff and all students 16 and older to be fully vaccinated.

At the national level, the country is waiting on the next steps when it comes to vaccine mandates.

Federal judges in Cincinnati are still considering if the Occupational Safety and Health Administration mandate for private employers will be allowed to go into effect.

The court leans conservative, but judges have not indicated what the ruling will be. It’s expected to come Dec. 10 at the earliest.
