The Advisory Committee on Immunization Practices (ACIP) recommends that once vaccination is underway in the initial phase (Phase 1a) of the COVID-19 vaccination program, which includes healthcare personnel and residents of long-term care facilities, planning should begin for subsequent phases, including Phase 1b (frontline essential workers and individuals 75 years of age and older) and Phase 1c (other essential workers, persons 65–74 years of age, and individuals 16–64 years of age with underlying medical conditions).
The following guide is intended to assist state, tribal, local, or territorial (STLT) immunization programs and other immunization partners in planning for vaccination of these populations.
