National Academies Recommends Four-Phase Approach on Vaccine Allocation

Situation Report | November 2, 2020

The National Academies of Sciences, Engineering, and Medicine has released a final report that recommends a four-phased equitable allocation framework for the development of national and local COVID-19 vaccine allocation guidelines.  

The first phase is split into two parts (1a and 1b) covering approximately 5 and 10 percent of the population, respectively.

Phase 1a would include front-line health workers (in hospitals, nursing homes, or providing home care), other at-risk health care facility workers and first responders. Phase 1b includes people of all ages with comborbid and underlying conditions that put them at significantly higher risk of severe COVID-19 disease or death as well as older adults in congregate settings.

The other phases include teachers, school staff, child care workers, and those in other high-risk settings like workers in the food supply system and public transit (phase 2); industries such as colleges and universities, hotels, banks, exercise facilities, and factories that pose moderately high risk of exposure (phase 3); and, lastly, everyone residing in the U.S. who did not have access to the vaccine in prior phases (phase 4).
