The categories will include workers in education and childcare, food and agriculture as well as emergency services.
"This expansion of eligibility will help ensure many of our essential workers, particularly those that are living in areas hardest hit, will have access to the vaccine," said Santa Clara County Health Officer Dr. Sara Cody.
The expansion falls under the state's Phase 1b, Tier 1 eligibility.

Santa Clara Director of Public Health, Rocia Luna, said they will be expanding hours at some of the vaccination sites to include evening and weekend time slots to account for those who work during the week.
They are also conducting door-to-door outreach to assist people who have not yet signed up if they are eligible.
"We are working closely with a large network of trusted community partners to ensure that our most impacted communities have access to vaccinations," said Rocio Luna, Deputy Director of Public Health for the County of Santa Clara.
Dr. Cody said the county has vaccinated 50% of residents over 75 with at least one dose. She said they are also close to 50% of those 65 and older as well.
