Associations between 5-year influenza vaccination and sociodemographic factors and healthcare access among Arkansans.

Despite wide availability, only 50.2% of the United States (US) adult population and 50.3% of adult Arkansans were vaccinated for influenza during the 2020-2021 influenza season. The proportion of the population vaccinated for influenza varies by age, sex, race/ethnicity, education, rural/urban residence, and income. However, measures of healthcare access have not been adequately investigated as predictors of influenza vaccination. Using a large, statewide random sample, this study examined 5-year influenza vaccination among Arkansans by sociodemographic characteristics (age, sex, race/ethnicity, education, rural/urban residence), general vaccine hesitancy, and healthcare access (having a primary care provider, having health insurance, forgoing health care due to cost, and frequency of doctor checkups). Older age, being female, being Hispanic, having a bachelor's degree or higher, having a primary care provider, visiting a doctor for a checkup in the past two years, and lack of hesitancy towards vaccines were significant predictors of receiving influenza vaccination.
