With coronavirus cases continuing to rise, Los Angeles is now considering a proposal to require proof of COVID-19 inoculation as a condition of entry at a host of indoor public spaces in what, if passed, would be the widest-ranging vaccination-verification effort in the city yet.

The motion, introduced Wednesday by City Council President Nury Martinez and Councilman Mitch O’Farrell, would require eligible individuals to demonstrate that they’ve received at least one vaccination dose to visit indoor places such as restaurants, bars, retail stores, gyms, spas, movie theaters, stadiums and concert venues.

The move comes amid a surge in coronavirus cases fueled by the highly infectious Delta variant, which has both public officials and private businesses scrambling to slow the spread. Some L.A. restaurants have already begun requiring proof of vaccination for customers, saying they hope that action can forestall the more intense restrictions seen earlier in the pandemic that pushed some retailers to their breaking point.
