New Orleans and San Francisco said Thursday that all patrons to bars, restaurants, gyms and other indoor spaces will be required to show proof of vaccination or a recent negative coronavirus test. New York City is adopting a similar requirement next week.

On Thursday, the U.S. Supreme Court ruled that Indiana University may keep its requirement that students attending classes be vaccinated against COVID-19. Justice Amy Coney Barrett turned down a challenge to the requirement without comment and without referring it to the full court.
