Abstract

COVID-19 vaccine hesitancy has been a major limiting factor to the widespread uptake of COVID-19 vaccination in the United States. A range of interventions, including mass media campaigns, have been implemented to encourage COVID-19 vaccine confidence and uptake. Such interventions are often guided by theories of behavior change, which posit that behavioral factors, including beliefs, influence behaviors such as vaccination. Although previous studies have examined relationships between vaccination beliefs and COVID-19 vaccination behavior, they come with limitations, such as the use of cross-sectional study designs and, for longitudinal studies, few survey waves. To account for these limitations, we examined associations between vaccination beliefs and COVID-19 vaccine uptake using data from six waves of a nationally representative, longitudinal survey of U.S. adults (N = 3,524) administered over a nearly 2-year period (January 2021-November 2022). Survey-weighted lagged logistic regression models were used to examine the association between lagged reports of vaccination belief change and COVID-19 vaccine uptake, using five belief scales: (1) importance of COVID-19 vaccines, (2) perceived benefits of COVID-19 vaccination, (3) COVID-19 vaccine concerns and risks, (4) normative beliefs about COVID-19 vaccination, and (5) perceptions of general vaccine safety and effectiveness. Analyses controlled for confounding factors and accounted for within-respondent dependence due to repeated measures. In individual models, all vaccination belief scales were significantly associated with increased COVID-19 vaccine uptake. In a combined model, all belief scales except the benefits of COVID-19 vaccination were significant predictors of vaccine uptake. Overall, belief scales indicating the importance of COVID-19 vaccines and normative beliefs about COVID-19 vaccination were the strongest predictors of COVID-19 vaccine uptake. Findings demonstrate that changes in vaccination beliefs influence subsequent COVID-19 vaccine uptake, with implications for the development of future interventions to increase COVID-19 vaccination.
