Californians must show proof of vaccination or a negative Coronavirus test within 72 hours before attending any indoor event with 1,000 or more guests, officials announced Wednesday. All such events are required to enforce the new policy beginning Sept. 20. and to continue until Nov. 1.

The new rule requires digital or physical proof. Self-attesting of vaccination status is no longer permitted. The rule is similar to mandates for health care workers, hospital visitors and all K-12 school staff.

“By requiring individuals to be vaccinated, or test negative for COVID-19 at large events, we are decreasing the risk of infection, hospitalization and death,” CDPH Director Dr. Tomas Aragon said. Hospitalizations have doubled in California, from 2,543 patients on July 23, to 7,166 on August 16 while the number of patients in intensive care units rose from 582 to 1,637. The vast majority of new cases are among those who are unvaccinated.

“If we want to end this pandemic and disease, we could do it in a month,” Newsom said at Claremont Middle School last week after announcing vaccine and testing mandates for education staff. “This disease is now a choice. The one thing that could end this pandemic once and for all is available in abundance to everybody that wants it. Regardless of your ability to pay, regardless of your immigration status: It’s available today.”
