Misinformation about vaccines on social media is a growing concern among healthcare professionals, medical experts, and researchers. Although such concerns often relate to the total sum of information flows generated online by many groups of stakeholders, vaccination controversies tend to vary across time, place, and the vaccine at issue. We studied content generated by administrators on three Facebook pages in Denmark established to promote critical debate about Human Papillomavirus (HPV) vaccination. We developed a qualitative coding frame allowing us to analyze administrators’ posts in terms of prevalent topics and intertextual material incorporated by linking and sharing. We coded more than a third of the posts (n = 699) occurring in the period from November 2012, when the first page was founded, to May 2019. We found that the pages mainly addressed the reports of adverse events following HPV vaccination and the (perceived) inadequate response of healthcare systems. To construct their central message, the pages assembled different sources, mostly reporting from Danish news media, but also personal narratives, scientific information, political assertions, and more. We conclude that HPV vaccination assemblages such as these pages are heterogeneous and contextual. They are not uniform sites of vaccine criticism, but rather seem to respond to and exchange information and misinformation within the communication environment in which they are embedded.

2012年至2019年丹麦三个HPV疫苗关键的Facebook页面上的疫苗组合

在社交媒体上有关疫苗的错误信息越来越引起医疗保健专业人员，医学专家和研究人员的关注。尽管这些担忧通常与许多利益相关者在线生成的信息流的总数有关，但疫苗的争议往往随时间，地点和所涉及的疫苗而变化。我们研究了管理员在丹麦三个Facebook页面上生成的内容，这些内容旨在促进有关人乳头瘤病毒（HPV）疫苗接种的批判性辩论。我们开发了一个定性编码框架，使我们可以根据链接和共享所包含的流行主题和互文材料来分析管理员的帖子。从2012年11月（第一页建立）到2019年5月，我们对超过三分之一的帖子（n = 699）进行了编码。我们发现这些页面主要针对HPV疫苗接种后不良事件的报告以及医疗系统的（感知）反应不足。为了构建他们的中心信息，这些页面汇集了不同的来源，主要来自丹麦新闻媒体的报道，还包括个人叙事，科学信息，政治主张等。我们得出的结论是，这些页面的HPV疫苗接种组合是异质的并且是上下文相关的。它们不是疫苗批评的统一场所，而是似乎在它们所嵌入的通信环境中做出响应并交换信息和错误信息。主要来自丹麦新闻媒体的报道，还包括个人叙述，科学信息，政治主张等。我们得出的结论是，这些页面的HPV疫苗接种组合是异质的并且是上下文相关的。它们不是疫苗批评的统一场所，而是似乎在它们所嵌入的通信环境中做出响应并交换信息和错误信息。主要来自丹麦新闻媒体的报道，还包括个人叙述，科学信息，政治主张等。我们得出的结论是，这些页面的HPV疫苗接种组合是异质的并且是上下文相关的。它们不是疫苗批评的统一场所，而是似乎在它们所嵌入的通信环境中做出响应并交换信息和错误信息。
