COVID-19 Vaccine

Prioritization & Allocation


Vaccine eligibility will be determined by phases of prioritization developed by the Centers for Disease Control and Prevention (CDC) through the Advisory Committee of Immunization Practices (ACIP) as well as guidance developed by the California Department of Public Health (CDPH) until sufficient supply of COVID-19 vaccine becomes available. Local planning is used to further refine these categories and assist in implementation based on the current status and trends in transmission in LA County.

LA County Vaccine Allocation Phases and Tiers
Phase 1A Priority Populations
  • Healthcare workers: Persons at high and moderate risk of exposure to SARS CoV-2 through their work in any role in direct health care or long-term care settings. This population includes persons at direct risk of exposure in their non-clinical roles, such as, but not limited to, environmental services, patient transport, or language interpretation.
  • Long-term care facility residents: Residents of skilled nursing facilities, assisted living facilities, and similar long-term care settings for older or medically vulnerable people.
Phase 1A

All groups in Phase 1A are now being offered vaccine.

Vaccination began in mid-December. It is estimated that everyone in Phase 1A will have been offered at least one dose of vaccine by late January/early February*.

Note: Vaccination is only available to the healthcare workers listed in Phase 1A who have the potential for direct or indirect exposure to patients or infectious materials. (Low risk healthcare workers such as administrative support staff WITHOUT routine in-person patient contact, will be offered vaccination in Phase 1B Tier2).

Healthcare Worker Risk Stratification

  • Moderate-risk employee: staff who have indirect or limited in-person patient contact (e.g. food services, medical records, front desk staff)
  • Low-risk employee: administrative support staff without routine in-person patient contact.
Administration of COVID-19 Vaccine to Healthcare Workers and Long Term Care Facility Residents

The current LA County Phase 1A administration of COVID-19 vaccine plan is as follows:

  • Acute care hospitals are overseeing the administration of vaccination to HCWs employed within their system.
  • Skilled Nursing Facility healthcare workers and residents are being vaccinated onsite by the facility staff, Public Health, community, or healthcare partners.
  • Healthcare workers and residents of other long-term care facilities (Community Care Facilities) will be vaccinated onsite thorough a federal pharmacy program.
  • All other healthcare workers will be vaccinated in community clinics and special vaccination sites by LAC DPH in collaboration with county, city, community, and healthcare partners. Visit the LAC DPH Healthcare Worker Vaccination webpage for more information on how to access vaccination.
Allocation Goals and Principles

The following are goals and principles guiding the vaccine allocation strategy based on CDC, ACIP, and CDPH recommendations:


  • Decrease death and serious disease
  • Preserve functioning of necessary healthcare services and the larger society
  • Reduce the additional burden the disease is having on people already facing healthcare and income disparities


  • Maximize benefits and minimize harms — Respect and care for people using the best available data to promote public health and minimize death and severe illness.
  • Mitigate health inequities — Reduce health disparities in the burden of COVID-19 disease and death, and make sure everyone has the opportunity to be as healthy as possible.
  • Promote justice — Treat affected groups, populations, and communities fairly. Remove unfair, unjust, and avoidable barriers to COVID-19 vaccination.
  • Promote transparency — Make a decision that is clear, understandable, and open for review. Allow and seek public participation in the creation and review of the decision processes.

In addition to these guiding values, additional operational considerations are necessary:

  • Efficient targeting —criteria to improve implementation feasibility.
  • Maximum coverage —criteria that maximizes actual recipients among intended recipients.
  • Minimum leakage —criteria that minimizes unintended recipients among actual recipients.
