The HPV vaccine is seen by many audiences as a health risk, but this perspective has seen little analysis. This study is the continuation of an analysis of the first decade of public, HPV-vaccine related Facebook posts. For this study, social amplification of risk framework concepts were analyzed to measure their relationships with post characteristics, engagement, and to see how those variables changed over time.
There were 6,506 public HPV vaccine-related Facebook posts (n = 6,506) within the first ten years after HPV vaccine's FDA approval (June 8, 2006 - June 8, 2016). Post characteristics, engagement, and social amplification of risk framework messages were coded (Krippendorf's alpha range: 0.67-1.00).
HPV vaccine risk amplification messages appeared in 39.5% of posts (n = 2,568), attenuated in 2.9% of post (n = 186), with the remaining 57.7% (n = 3,752) doing neither. Compared to groups, individuals were overrepresented in authoring HPV vaccine risk amplifying messages. Hyperlinks and negative tone towards the HPV vaccine. HPV vaccine risk amplifying messages also received significantly greater reaction (r = 0.050, p < 0.0001), comment (r = 0.030, p < 0.0001), and share counts (r = 0.028, p < 0.0001). The data showed evidence of forward momentum (Durbin-Watson values) of HPV vaccine risk amplification (0.006), related ripples (0.530), and impacts (1.376).
Nearly four out of every ten Facebook posts about the HPV vaccine contained messages that amplified the risk of HPV vaccine and the data suggest that these posts had momentum over time. Research must continue to address the perception of vaccine safety where the vaccine is perceived as the health threat, with deep research into online communities to discover the perceived ripples and impacts.
许多人认为 HPV 疫苗存在健康风险，但这一观点很少得到分析。本研究是对 HPV 疫苗相关 Facebook 帖子发布后第一个十年公众相关内容的分析的延续。本研究利用社会风险放大框架的概念进行分析，以衡量其与帖子特征、参与度的关系，并观察这些变量随时间的变化。
在 HPV 疫苗获得 FDA 批准后的第一个十年内（2006 年 6 月 8 日至 2016 年 6 月 8 日），共有 6506 条关于 HPV 疫苗的 Facebook 帖子（n=6506）。对帖子特征、参与度和社会风险放大框架信息进行编码（克里彭多夫 α 值范围：0.67-1.00）。
HPV 疫苗风险放大信息出现在 39.5%的帖子中（n=2568），在 2.9%的帖子中被削弱（n=186），而剩下的 57.7%（n=3752）则没有。与其他群体相比，作者更倾向于创作 HPV 疫苗风险放大信息。帖子中含有超链接和对 HPV 疫苗的负面评价。HPV 疫苗风险放大信息也获得了更多的点赞（r=0.050，p<0.0001）、评论（r=0.030，p<0.0001）和分享（r=0.028，p<0.0001）。数据显示 HPV 疫苗风险放大存在前进的动力（杜宾-沃森值）（0.006）、相关波动（0.530）和影响（1.376）。
每十个关于 HPV 疫苗的 Facebook 帖子中就有近四个帖子包含放大 HPV 疫苗风险的信息，并且数据表明这些帖子随着时间的推移具有影响力。研究必须继续关注疫苗安全性的认知，即疫苗被视为健康威胁的情况，并深入研究在线社区，以发现感知到的波动和影响。
