California has updated Phase 1B of its vaccination plan to include essential workers in the education and childcare, emergency services, and food and agriculture (e.g. farmworkers) sectors, in addition to adults over age 65.  Essential workers, including healthcare workers who have been prioritized since the start of the vaccine roll-out, provide critical services and have a risk of exposure to COVID-19 at work.  This guidance is current as of February 4, 2021, and went into effect in San Mateo County on February 22nd.  Please check the links below for the most up-to-date information.
