CA Becomes First State To Require Vaccine Or Testing For Indoor Events

California is the first state to require proof of vaccination or a negative COVID-19 test for large indoor events. That's what Governor Gavin Newsom said on Twitter about a new rule going into place on Friday. The rule applies to what the state is calling "mega events," which have 1,000 people or more in attendance. State Public Health Officer Dr. Tomas Aragon says the new mandate is necessary to minimize the "risk of infection, hospitalization, and death." Health officials say the Delta variant is highly transmissible, making it easier to spread in large crowds.
