在过去的十年中，反疫苗接种言论已成为有关儿童疫苗接种公共卫生实践的主流话语的一部分。这些组织利用社交媒体来培育在线空间，加强和普及反疫苗接种的话语。在本文中，我们研究的特点和话语中存在的六个流行的反疫苗接种的Facebook页面。我们使用一系列方法来检查这些大规模数据集，包括社交网络分析，使用历史人口普查数据进行性别预测，以及用于主题分析的生成统计模型（潜在Dirichletallocation）。我们发现，当今的话语围绕道德义愤和机构政府和媒体的结构性压迫，这表明了一个强大的逻辑“阴谋式”的信仰和思维。此外，Facebook上的反疫苗接种页面反映了一场高度“女性化”的运动，绝大多数参与者是女性。尽管Facebook上的反疫苗接种网络规模庞大，且覆盖全球，但评论活动子网络似乎是“小世界”。这表明，社交媒体可能在传播反疫苗接种思想和使该运动在全球范围内持久化方面发挥作用。
Over the past decade, anti-vaccination rhetoric has become part of the mainstream discourse regarding the public health practice of childhood vaccination. These utilise social media to foster online spaces that strengthen and popularise anti-vaccination discourses. In this paper, we examine the characteristics of and the discourses present within six popular anti-vaccination Facebook pages. We examine these large-scale datasets using a range of methods, including social network analysis, gender prediction using historical census data, and generative statistical models for topic analysis (Latent Dirichletallocation). We find that present-day discourses centre around moral outrage and structural oppression by institutional government and the media, suggesting a strong logic of 'conspiracy-style' beliefs and thinking. Furthermore, anti-vaccination pages on Facebook reflect a highly 'feminised' movement the vast majority of participants are women. Although anti-vaccination networks on Facebook are large and global in scope, the comment activity sub-networks appear to be 'small world'. This suggests that social media may have a role in spreading anti-vaccination ideas and making the movement durable on a global scale.
