In this study we explored sociodemographic disparities in COVID-19 vaccine access upon initial rollout at Publix grocery store locations throughout Florida in January 2021. Florida officials reported that they chose Publix stores for the vaccine rollout because the chain has so many stores in the state and was considered at the time to be better prepared than other retailers. Data on education levels, ethnicity, race, percentage at or below the poverty level, and percentage single-parent households were collected from the 2019 census for 974 Florida ZIP codes. We used hotspot analysis to measure spatial clustering of Publix vaccination sites per 100,000 people. We identified hot spots (areas with greater vaccine availability) in moderately populated areas where the population was significantly older, richer, and Whiter than in areas of lower vaccine availability (cold spots). Cold spots were identified in areas of low and high population density, areas with a higher proportion of Hispanic residents, and areas with a higher proportion of single-parent households, including Miami-Dade County and inland regions of Florida. Multivariate analysis showed strong associations between the number of vaccination sites in a ZIP code and race and ethnicity and a weaker association with percentage of residents at or below the poverty level. Future vaccine distribution should continue to be monitored through a socioeconomic lens to help prevent unequal access.
