This study proposes the use of Geographic Information Systems (GIS) techniques to prioritize allocation of scarce COVID-19 vaccine resources in the United States to facilitate vaccine distribution. We adapt the framework from the U.S. Centers for Disease Control and Prevention (CDC), John Hopkins University and the National Academies of Sciences, Engineering, and Medicine following a principle of maximum benefit, equal concern, and mitigation of health inequalities. Using census, business data, and current infection data, we quantify each county’s need based on a 4-phase allocation framework: (1) frontline health workers and first responders, people with comorbidity and older adults in congregate or overcrowded settings, (2) K-12 teachers and school staff and child care workers, critical workers in high-risk settings, people with moderate comorbid conditions, people in homeless shelters or group homes and staff, incarcerated/detained people and staff, and all older adults, (3) young adults, children, workers in industries important to the functioning of society, and (4) the rest of the population. The web-based GIS allows decision makers to allocate scarce vaccine supplies to specific areas for vaccination based on the population characteristics in the target area.
