The CDC  has published The Advisory Committee on Immunization Practices’ Interim Recommendation for Allocating Initial Supplies of COVID-19 Vaccine—United States, 2020 in an Early Release MMWR on December 3. 
 
As interim guidance, the Advisory Committee on Immunization Practices (ACIP) recommends that both 1) healthcare personnel and 2) residents of long-term care facilities be offered COVID-19 vaccine in the initial phase of the vaccination program. All CDC information on current COVID-19 vaccine recommendations is available online at www.cdc.gov/vaccines/hcp/acip-recs/vacc-specific/covid-19.html.

In conjunction with the interim ACIP recommendations, CDC published "Clinical Considerations" on a web page titled Interim Considerations for COVID-19 Vaccination of Healthcare Personnel and Long-Term Care Facility Residents.

This page provides information on additional topics, including sub-prioritization information of COVID-19 vaccination for healthcare personnel (HCP) and for those in long-term care facilities. It also discusses vaccination of pregnant and breastfeeding HCP and post-vaccination symptoms in HCP.
