Replication Data for: Public Attitudes toward COVID-19 Vaccination: The Role of Vaccine Attributes, Incentives, and Misinformation

In recent decades, misinformation about vaccines has been associated with decreased vaccination rates and now threatens COVID-19 vaccination specifically. We developed and fielded an original survey experiment to understand the relationship between misinformation uptake, vaccine attributes, and COVID-19 vaccine preferences. Individuals’ willingness to receive the COVID-19 vaccine was most closely associated with higher degrees of vaccine efficacy, while a high incidence of minor side effects, a co-pay, and Emergency Use Authorization to fast-track the vaccine decreased willingness. While Republicans, men, and younger Americans were more likely to believe misinformation about COVID-19, individual levels of misinformation were not correlated negatively with either general perceptions of vaccine safety or willingness to accept a COVID-19 vaccine. Findings have implications for developing public health campaigns that will increase levels of community vaccination.

近数十年来，疫苗错误信息与疫苗接种率下降存在显著关联，如今其更是对新冠疫苗接种构成了具体威胁。本研究设计并实施了一项原创性调查实验，以探究错误信息接收量、疫苗属性与新冠疫苗偏好之间的内在联系。研究发现，民众接种新冠疫苗的意愿与更高的疫苗有效性关联最为紧密；而小额副作用高发、自付共付费用以及为疫苗开通快速审批通道的紧急使用授权（Emergency Use Authorization），均会降低民众的接种意愿。尽管共和党选民、男性与年轻美国群体更易轻信新冠相关错误信息，但个体接触错误信息的程度并未与疫苗安全性的普遍认知或新冠疫苗接种意愿呈负相关。本研究结果可为制定提升社区疫苗接种率的公共卫生宣传活动提供重要参考。
