了解社交媒体上的反疫苗接种工作所构成的威胁至关重要，因为全球范围内对COVID-19疫苗接种计划的需求即将到来。我们在全球范围内评估社交媒体和在线外国虚假信息活动对疫苗接种率和疫苗安全态度的影响。我们使用一个大n跨国回归框架来评估社交媒体对全球疫苗犹豫的影响。为此，我们从两个方面对社交媒体的使用进行了操作：公众使用它来组织行动（使用数字社会项目指标），以及社交媒体上关于疫苗的负面话语水平（使用2018-2019年世界上所有地理编码推文的数据集）。此外，我们还测量了每个国家社交媒体上外国来源的协调虚假信息操作的水平（使用数字社会项目指标）。疫苗犹豫的结果可以通过两种方式来衡量。首先，我们使用民意调查每个国家的公众比例认为疫苗是不安全的（使用惠康全球监测137个国家的指标）。其次，我们使用了世界卫生组织166个国家的实际疫苗接种率的年度数据。我们发现，使用社交媒体组织线下行动，高度预测接种疫苗不安全的信念，随着社交媒体上组织活动的增加，这种信念也会增加。此外，外国虚假信息的流行在预测平均疫苗接种覆盖率随时间推移而下降方面具有高度的统计学和实质性意义。在5分虚假信息量表中向上移动1分与平均疫苗接种覆盖率同比下降2个百分点有关。我们还发现了外国虚假信息与有关疫苗接种的负面社交媒体活动之间的联系。外国虚假信息的实质性影响是使中等国家的负面疫苗推文数量增加15%。社交媒体上的组织与公众对疫苗安全性的怀疑之间存在着重要的关系。此外，外国虚假信息运动与疫苗接种覆盖率下降之间存在着实质性关系。
Understanding the threat posed by anti-vaccination efforts on social media is critically important with the forth coming need for world wide COVID-19 vaccination programs. We globally evaluate the effect of social media and online foreign disinformation campaigns on vaccination rates and attitudes towards vaccine safety. We use a large-n cross-country regression framework to evaluate the effect of social media on vaccine hesitancy globally. To do so, we operationalize social media usage in two dimensions: the use of it by the public to organize action (using Digital Society Project indicators), and the level of negatively oriented discourse about vaccines on social media (using a data set of all geocoded tweets in the world from 2018-2019). In addition, we measure the level of foreign-sourced coordinated disinformation operations on social media ineach country (using Digital Society Project indicators). The outcome of vaccine hesitancy is measured in two ways. First, we use polls of what proportion of the public per country feels vaccines are unsafe (using Wellcome Global Monitor indicators for 137 countries). Second, we use annual data of actual vaccination rates from the WHO for 166 countries. We found the use of social media to organise offline action to be highly predictive of the belief that vaccinations are unsafe, with such beliefs mounting as more organisation occurs on social media. In addition, the prevalence of foreign disinformation is highly statistically and substantively significant in predicting a drop in mean vaccination coverage over time. A 1-point shift upwards in the 5-point disinformation scale is associated with a 2-percentage point drop in mean vaccination coverage year over year. We also found support for the connection of foreign disinformation with negative social media activity about vaccination. The substantive effect of foreign disinformation is to increase the number of negative vaccine tweets by 15% for the median country. There is a significant relationship between organisation on social media and public doubts of vaccine safety. In addition, there is a substantial relationship between foreign disinformation campaigns and declining vaccination coverage.
