New study investigates California's possible herd immunity to COVID-19

Researchers at Stanford Medicine are working to find out what proportion of Californians have already had COVID-19. The new study could help policymakers make more informed decisions during the coronavirus pandemic.

The team tested 3,200 people at three

Bay Area locations on Saturday using an antibody test for COVID-19 and expect to release results in the coming weeks. The data could help to prove COVID-19 arrived undetected in California much earlier than previously thought.

The hypothesis that COVID-19 first started spreading in California in the fall of 2019 is one explanation for the state's lower than expected case numbers.
