Association Between County-Level Social Vulnerability and Vaccine-Related Attitudes and Hesitancy Toward COVID-19...

Understanding attitudes and behaviors related to vaccination is critical for enhancing COVID-19 vaccination acceptance and reducing disparities in vaccination coverage. This study examines disparities in vaccine-related attitudes and COVID-19 vaccine hesitancy in the United States in relation to community-level social vulnerability.

This study analyzed cross-sectional national surveys conducted repeatedly between July 2020 and August 2021 (n = 6716). We assessed the association between county-level social vulnerability and general vaccine-related attitudes, as well as COVID-19 vaccine hesitancy. We developed Poisson models with robust variance estimation. The analysis also included the association of county social vulnerability with parental COVID-19 vaccine hesitancy.

Living in counties with high Socioeconomic Status vulnerability was associated with less vaccine support (adjusted Prevalence Ratio (aPR) 1.10; 95% CI 1.05-1.14) and residing in counties with high Household Characteristics vulnerability was associated with higher likelihood of COVID-19 vaccine hesitancy (aPR 1.13; 95% CI 1.07-1.20). In contrast, high vulnerability in the Racial and Ethnic Minority was associated with more positive attitudes toward vaccines (aPR 0.91; 95% CI 0.88-0.94) and lower COVID-19 vaccine hesitancy for both themselves (aPR 0.81; 95% CI 0.76-0.87) and children (aPR 0.84; 95% CI 0.75-0.94), after adjusting for sociodemographic factors.

Our study highlights the importance of addressing vulnerabilities related to socioeconomic status and household characteristics to reduce disparities in vaccine perceptions and hesitancy in socially vulnerable populations. The findings provide evidence for targeted public health interventions at the community level. They also demonstrate that the relationship between social vulnerability and vaccine attitudes varies across different vulnerability components.
