From the Introduction: "Delaware, located in the Mid-Atlantic region, has a population of 972,332, which is 45th in population size among all U.S. states, with significant increases during the spring/summer seasons due to an influx of visitors to its beaches. While most states have both local and state health departments, the Division of Public Health (DPH) within the Department of Health and Social Services (DHSS) serves as the public health entity for both state and local needs. During this COVID-19 [coronavirus disease 2019] pandemic, effective allocation and administration of a vaccine will significantly reduce COVID-19 effects on Delaware's health, society, and economy. Although the overarching aim is to vaccinate all persons in Delaware, the initial vaccine supply will be insufficient to meet this goal. Delaware will use its experience in mass vaccination during the novel H1N1 [Hemagglutinin Type 1 and Neuraminidase Type 1] Influenza pandemic and the yearly influenza season, as well as the infrastructure created for COVID-19 testing to develop and implement a phased approach to vaccine distribution."
