The impact of politics, religion, and rurality on COVID-19 vaccine hesitancy in Oregon: a cross-sectional study.

Abstract

Vaccine hesitancy has been a major barrier to mitigating the effects of COVID-19, especially in rural Oregon, USA. This study assessed the influence of political affiliation, religious identity, and rurality on vaccine hesitancy in counties across Oregon. Cross-sectional association analysis was performed using public data on US President Trump votership in the 2020 election, White Christian identity, population density, and COVID-19 vaccination data for adults as of 29 August 2021. By 29 August 2021, 68.0% of adults had been fully vaccinated in Oregon. Trump votership was the strongest independent association with vaccination status in Oregon (r=0.90, p<0.01), followed by White Christian identity (r= -0.69, p<0.01), and population density (r=0.55, p<0.01). In multivariate analysis, White Christian identity and political affiliation with Trump in the 2020 election explained 84.1% of the variability in COVID-19 vaccination status in Oregon counties. White Christian identity, Trump affiliation, and rurality were identified as factors in vaccine hesitancy among counties in Oregon. Without addressing these factors in public health outreach, vaccine hesitancy is likely to continue unabated.
