As the highly contagious delta variant drives up COVID-19 cases throughout well-vaccinated California, the state announced Monday it will require all public and private health workers as well as state employees to get vaccinated and prove they had the shots or be subject to at least weekly testing for the disease.

The order, which comes amid growing alarm among health experts calling for tougher action and mandates, means health and state workers will no longer be allowed to “self-attest” that they were vaccinated.
