Although social media can be a source of guidance about HPV vaccination for parents, the information may not always be complete or accurate. We conducted a retrospective content analysis to identify content and frequencies of occurrence of disinformation and misinformation about HPV vaccine posted on Twitter between December 15, 2019, through March 31, 2020, among 3876 unique, English language #HPV Tweets, excluding retweets. We found that 24% of Tweets contained disinformation or misinformation, and the remaining 76% contained support/education. The most prevalent categories of disinformation/misinformation were (1) adverse health effects (59%), (2) mandatory vaccination (19%), and (3) inefficacy of the vaccine (14%). Among the adverse health effects Tweets, non-specific harm/injury (51%) and death (23%) were most frequent. Disinformation/misinformation Tweets vs. supportive Tweets had 5.44 (95% CI 5.33-5.56) times the incidence rate of retweet. In conclusion, almost one-quarter of #HPV Tweets contained disinformation or misinformation about the HPV vaccine and these tweets received higher audience engagement including likes and retweets. Implications for vaccine hesitancy are discussed.
虽然社交媒体可以成为家长了解 HPV 疫苗接种的信息来源，但这些信息并不总是完整或准确的。我们进行了一项回顾性内容分析，以确定 2019 年 12 月 15 日至 2020 年 3 月 31 日期间，在 3876 条独特的、英语语言的#HPV 推文中，除了转发的推文外，关于 HPV 疫苗的虚假和错误信息的内容和出现频率。我们发现，24%的推文包含虚假或错误信息，其余 76%的推文包含支持/教育内容。虚假/错误信息最常见的类别是：（1）不良健康影响（59%），（2）强制接种（19%），（3）疫苗无效（14%）。在关于不良健康影响的推文中，非特异性伤害/损伤（51%）和死亡（23%）最为常见。虚假/错误信息推文与支持性推文的转发率之比为 5.44（95%CI 5.33-5.56）。总之，近四分之一的#HPV 推文包含关于 HPV 疫苗的虚假或错误信息，这些推文获得了更高的受众参与度，包括点赞和转发。讨论了对疫苗犹豫的影响。
