The impact of financial incentives on COVID-19 vaccination intention among a sample of U.S. adults.

Overview

Financial incentives are one of several strategies that have been explored to enhance COVID-19 vaccine uptake. Although widely discussed, it is unclear how much of an incentive and for which subset of individuals incentives would be effective. This study explored the impact of hypothetical $600 or $1200 incentives on COVID-19 vaccination intention. From a nationally representative panel of U.S. adults, 346 individuals reported hesitance towards COVID-19 vaccination and were then asked about their willingness to accept a vaccine if offered hypothetical incentives. Results indicated 26.89% would get vaccinated if offered $600, and 30.06% if offered $1200. In the multivariable model that included sociodemographic and attitudinal predictors of vaccine uptake, those classified as 'wait-and-see' compared to those classified as non-acceptors were more likely to accept COVID-19 vaccines when given financial incentives, and those who believed more strongly in the benefits of COVID-19 vaccines were more likely to accept a vaccine when first offered hypothetical $600 and then $1200 incentives. Individuals unsure if they ever had COVID-19 were significantly less likely to be willing to get the vaccine for $1200 as compared to those who believed they previously had COVID-19. These results suggest that financial incentives can increase intention to receive a COVID-19 vaccine.
