Determinants of COVID-19 skepticism and SARS-CoV-2 vaccine hesitancy: findings from a national population survey of U.S. adults

Abstract

AbstractBackgroundThe enduring presence of COVID-19 skepticism and SARS-CoV-2 vaccine hesitancy is an ongoing impediment to the global response effort to the current pandemic. This study seeks to identify determinants of skepticism and vaccine hesitancy in U.S. adults.MethodsData are from the Values and Beliefs of the American Public Survey, conducted in 2021 by the Gallup Organization in conjunction with Baylor University. The survey used stratified random probability sampling of the U.S. adult population (N = 1222). Outcome measures were respective single items assessing COVID-19 skepticism and SARS-CoV-2 vaccine hesitancy. Exposure variables included political, religious, and sociodemographic indicators, and moderators assessed personal history of COVID-19 and losing a relative or close friend to COVID-19.ResultsSkepticism and vaccine hesitancy were strongly associated with conservative and Republican political preference and conservative religious beliefs, and less so with socioeconomic status. Personal experience with COVID-19 did not mitigate the effect of politics on skepticism and barely reduced the odds for hesitancy. Results confirm that attitudes toward COVID-19 are politically and religiously conditioned, and are especially a product of conservative political preference.ConclusionSkepticism about COVID-19 and hesitancy regarding SARS-CoV-2 vaccination are highest among the political and religious right. Efforts to increase immunization through public education may be inadequate; resistance appears ideological. Other solutions may need to be considered, which risk widespread pushback both politically and religiously motivated.
