Yes, as of September 2021, California has mandated COVID-19 vaccinations for certain groups of employees. On August 5, 2021, California Governor Gavin Newsom announced that all healthcare workers in the state, including employees in hospitals, nursing homes, and other healthcare settings, must be fully vaccinated against COVID-19 by September 30, 2021. This mandate applies to both public and private sector healthcare workers.

In addition, on August 20, 2021, the California Department of Public Health issued a public health order requiring all workers in certain high-risk settings to either show proof of full vaccination or undergo weekly COVID-19 testing.

High-Risk Settings Covered by the Order

• Acute healthcare settings (hospitals, skilled nursing facilities, etc.)
• Correctional facilities and detention centers
• Homeless shelters and other congregate settings
• Adult and senior care facilities
• K-12 schools and higher education institutions

This order took effect on August 23, 2021 and applies to both public and private sector employees in these settings.

It's worth noting that vaccine mandates and requirements are subject to change, and it's important to check the most up-to-date information and guidance from California public health officials and your employer. If you are unsure whether this mandate applies to you, you should consult with an employment attorney.
