New York City will become the first major U.S. city to require proof of Covid-19 vaccination for customers and staff at restaurants, gyms and other indoor businesses as the country enters a new phase of battling the highly contagious Delta variant.

New York Governor Andrew Cuomo unveiled a plan to revive New York City’s renowned arts scene from its pandemic-induced dormancy and also allowed city restaurants to reopen their indoor dining areas sooner than previously announced.

New Jersey and California took a big step toward letting businesses resume their pre-pandemic lives, by allowing restaurants to begin limited indoor dining, as coronavirus cases abated nationwide even as some new hotspots emerged.
