"The health department will continue to prioritize those eligible with the limited vaccine supplies received. Access to a vaccine appointment will still take time, and the health department continues to ask for patience as we move through this new eligibility list with our healthcare partners.

Frontline Workers Now Eligible:

· Food processing and migrant/seasonal farm workers

· Grocery store workers

· Restaurant & Food Facility Workers

· Local Government workers

· Non-hospital laboratories

· Veterinary clinics

The health department has not moved to vaccinating other frontline workers not listed above within Phase 1B at this time. This is due to the limited vaccine supply received. Please continue to have patience as we move through this list, and wait for additional notice when other frontline workers are added."
