From the Executive Summary: "In November 2020, the 'CommuniVax Coalition' was formed for the purpose of strengthening COVID-19 [coronavirus disease 2019] vaccination efforts across the United States. The coalition's focus is on communities of color and the issues they face that impede vaccine access. These include issues surrounding health communication mode and content, effective policy development, intervention design and implementation, and inclusive service delivery practices. Alabama was chosen as a coalition member because it has a substantial minority population, and because, as a rural state, it faces particular public health challenges--a substantial poverty rate, limited transportation and technology access, and a shrinking healthcare infrastructure. The 6 counties targeted in our study (Bibb, Greene, Hale, Perry, Pickens, and Tuscaloosa) exemplify these public health challenges. For example, Perry County has the lowest life expectancy in Alabama (72.3 years). It has a 35% poverty rate. There is no hospital, and its public health department is open 3 days per week. Only 40% of the county's African American population were vaccinated as of August 3, 2021. This compares favorably with the percentage of the White population vaccinated (34%) but is 27 percentage points below African American representation in the county population."
