Paper Title
Measuring Spatial Accessibility of Covid-19 Vaccination Sites
Abstract
The spatial distribution and allocation of healthcare resources play a crucial role in addressing health inequity
issues. This study examines the spatial patterns of COVID-19 vaccination services in Nueces County, Texas. The spatial
accessibility of vaccination sites was measured at the block group level using the two-step floating catchment area (2SFCA),
a widely used method for measuring spatial accessibility to healthcare facilities. The study found remarkable variations in
spatial accessibility to vaccination sites across different communities within Nueces County. Neighborhoods in rural and
underserved communities in the northwest and southwest areas of Nueces County exhibited lower accessibility. The study
emphasizes the importance of addressingspatial accessibility inequities in vaccination distribution plans to ensure equal
access to vaccine services,particularly in rural and underserved areas. These findings have implications for public health
planners and decision-makers in identifying areas with limitedaccess to vaccination services, guiding the allocation of
vaccination resources, and facilitatinghealthcare planning efforts. Ultimately, these effortshelp address health inequities by
bridging the gaps in spatial accessibility and ensuring the equitable distribution of vaccination resources.
