PROJECT SUMMARY: Sarah Nowak, PhD, Research Project Leader (RPL) The World Health Organization (WHO) has identified vaccine hesitancy as one of the top ten threats to global health. Vaccine hesitancy has been associated with beliefs that may be seemingly unrelated to vaccines, including both true conspiracy beliefs. When beliefs become part of the cultural norms of a group they are known as cultural scaffold beliefs; some cultural scaffold beliefs are strongly intertwined with perceptions of disease and vaccines. Nevertheless, most interventions developed to increase vaccine acceptance act on perceptions of either the vaccine-preventable disease (e.g., cautioning about risks) or the vaccine itself (e.g., messages about vaccine safety) without considering the underlying scaffold beliefs. Perhaps not surprisingly, the efficacy of such interventions has been disappointing. Our long-term goal is therefore to develop interventions that act on cultural scaffold beliefs to reduce global vaccine hesitancy. Increasing the voluntary vaccination rate could prevent up to 1.5 million deaths globally each year. In Brazil, President Jair Bolsonaro has endorsed and disseminated misinformation and false conspiracy theories about COVID-19 and its vaccines. Furthermore, Brazil has one of the world’s most successful childhood vaccination programs, making it an excellent case study to examine the relationship between COVID-19 misinformation cultural scaffold beliefs and adoption of vaccine-hesitant beliefs related to childhood vaccination. We will use social media data from Brazil to address our overarching hypothesis that vaccine hesitancy within a community is strongly influenced by prevailing cultural scaffold beliefs in the following three aims: Aim 1: Determine the association between COVID-19 conspiracy beliefs and childhood vaccine hesitancy. Aim 2: Determine how receipt of anti-vaccine versus pro-vaccine information influences decision making in vaccine-uncertain parents. Aim 3: Develop an agent-based modeling tool for studying the joint dynamics of cultural scaffold and vaccine hesitancy beliefs.

项目摘要：Sarah Nowak，博士，研究项目负责人(RPL) 世界卫生组织(WHO)已将疫苗接种迟缓确定为全球面临的十大威胁之一 健康。疫苗的犹豫不决与看似与疫苗无关的信念有关， 包括两种真正的阴谋论信仰。当信仰成为一个群体的文化规范的一部分时，它们就是 被称为文化支架信仰；一些文化支架信仰与 疾病和疫苗。尽管如此，大多数干预措施的发展是为了提高疫苗接受率。 对疫苗可预防的疾病(例如，警告风险)或疫苗本身的看法(例如， 关于疫苗安全性的信息)，而不考虑潜在的脚手架信仰。也许并不令人惊讶， 此类干预措施的效果一直令人失望。因此，我们的长远目标是发展 根据文化支架信念采取行动的干预措施，以减少全球疫苗的犹豫不决。增加自愿性 疫苗接种率每年可防止全球多达150万人死亡。 在巴西，贾尔·博尔索纳罗总统支持并散布错误信息和虚假阴谋。 关于新冠肺炎及其疫苗的理论。此外，巴西是世界上最成功的国家之一 儿童疫苗接种计划，使其成为检验两者之间关系的一个很好的案例研究 新冠肺炎错误信息、文化支架信念与儿童时期接种疫苗犹豫不决的信念 接种疫苗。 我们将使用来自巴西的社交媒体数据来解决我们的总体假设，即疫苗在 一个社区在以下三个目标上受到主流文化支架信仰的强烈影响： 目的1：确定新冠肺炎阴谋论信念与儿童疫苗迟疑之间的关联。 目标2：确定接受反疫苗和支持疫苗的信息对决策的影响 疫苗--不确定的父母。 目的3：开发一个基于智能体的建模工具，用于研究培养支架与疫苗的联合动力学 犹豫的信念。
