Abstract

This study was an investigation of how disability status, types, sociodemographic indicators, and reasons for not receiving vaccinations influenced COVID-19 vaccination rates among individuals with disabilities in the United States. Despite efforts, vaccination disparities persisted, necessitating an understanding of barriers to uptake. Using intersectionality theory and the social determinants of health framework, this study examined the impact of marginalized identities and structural inequalities. Key questions included the association between disability status and vaccination uptake, differences among disability types moderated by sociodemographic factors, and the interaction between disability status and reasons for not vaccinating. Household Pulse Survey data from the US Census Bureau were used in this study with logistic regression analyses assessing these relationships. Findings revealed that while disability status and sociodemographic variables alone did not significantly predict vaccination uptake, disability type was crucial, indicating the need for targeted interventions. These results support inclusive public health policies addressing specific barriers faced by individuals with disabilities and promoting equitable healthcare services and vaccination programs. Understanding the interplay between disability status, sociodemographic factors, and vaccination behavior may result in targeted strategies to ensure no population segment is left behind, fostering positive social change toward a more inclusive and equitable society.
