City officials in New York have started to enforce a vaccine mandate. People entering restaurants, gyms, theaters and museums have to show proof they have been vaccinated against coronavirus.
Business owners learned about the requirements last month. Now, they have to check that patrons aged 12 and older have received at least one dose. Two thirds of eligible New Yorkers have got at least one shot.
The city has sent out inspectors to check that owners are complying. Those who don't face penalties that start at 1,000 dollars and rise to 5,000 dollars.
Many theater operators on Broadway are reopening their doors. They will have to check audience members are fully vaccinated and wearing masks.
City officials in San Francisco started enforcing their mandate last month. They require patrons to be fully vaccinated.
Some politicians have pushed back against such rules. The Governor of Florida, Ron DeSantis, threatened local governments and businesses that require proof of vaccination with fines of 5,000 dollars for every violation.
