RAPID: Informed and Ecological Decision Making of COVID-19 Vaccination

接种疫苗是预防2019冠状病毒病（COVID-19）等传染病和促进群体免疫的最有效方法。然而，如果人们犹豫是否接种疫苗，群体免疫可能会减缓或停滞。该项目旨在促进知情的疫苗接种决定。该研究旨在阐明人们的疫苗接种决策如何根据其社会背景而演变。该项目的新奇在于随着时间的推移跟踪参与者，以评估他们在现实世界中对疫苗接种的决策。该项目将推进危机期间风险沟通和不确定情况下决策的最新水平。该项目将确定有关COVID-19疫苗的有效沟通，这些沟通是公众可以理解和适用的。该项目最终可提高人口的免疫接种率，使其达到群体免疫和免疫接种的集体健康效益的门槛。该项目包括四项任务，将促进对风险和不确定性下人类疫苗接种决策的理解。（1）通过利用卫生领域的风险沟通标准，开发关于COVID-19疫苗的沟通，这些疫苗在完整性、透明度和正确性方面存在实验性差异。 (2)评估提议的沟通在提高人们对COVID-19疫苗的认识和告知其疫苗接种决定方面的有效性。 (3)检查拟议的沟通在现实世界应用环境中告知人们疫苗接种决定的有效性。(4)调查人们如何应对不同情况下的不确定性，以了解疫苗接种决策如何在当前的疫苗接种活动中演变。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Vaccination is the most effective method to prevent infectious diseases like coronavirus disease 2019 (COVID-19) and prompt herd immunity. However, herd immunity could be slowed or stalled if people hesitated to be vaccinated. This project aims to facilitate informed vaccination decisions. The research aims to illuminate how people’s vaccination decisions evolve in response to their social context. The project’s novelty is to follow participants over time to evaluate their real-world decision making about vaccination. The project will advance the state-of-the-art on risk communication during crises and decision-making under uncertainty. The project will identify effective communication about COVID-19 vaccines that are understandable by, and applicable to, the public. The project could ultimately improve the immunization rate of the population to pass the threshold for herd immunity and the collective health benefits of immunization. The project entails four tasks that will advance the understanding of human vaccination decision-making under risk and uncertainty. (1 ) Develop communications about the COVID-19 vaccines that are experimentally varied in completeness, transparency, and correctness by leveraging the standards of risk communication in the health domain. (2) Evaluate the effectiveness of proposed communications in enhancing people’s knowledge of COVID-19 vaccines and informing their vaccination decisions. (3) Examine the effectiveness of proposed communications on informing peoples’ vaccination decisions in real-world application settings. (4) Investigate how people respond to uncertainties of different situations in order to understand how vaccination decisions evolve throughout the current vaccination campaign.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
