Background: HPV vaccination is an effective way in preventing cervical cancer. However, HPV vaccination coverage rate has fallen to only a few percent in Japan. Anti HPV-vaccination websites often use narratives of those who have experienced adverse reactions to HPV vaccine to enhance their persuasiveness. Scholars suggest using the same medium to promote HPV vaccination online; e.g., presenting narratives of those who have experienced cervical cancer. We examined the amount of narratives used on Japanese pro- and anti-HPV vaccination websites. Methods: We conducted online searches using two major search engines (Googl.jp and Yahoo!.jp). Identified websites were classified as “pro,” “anti,” or “neutral” depending on their claims. Two independent raters coded the pro and anti websites and counted the number of narratives of people who experienced side effects of HPV vaccine or cervical cancer. Results: A total 26% of anti websites posted narratives on side effects. No pro websites posted narratives about having cervical cancer. Conclusion: Pro-HPV vaccination websites is recommended to post narratives to enhance the persuasiveness of their arguments.
人乳头瘤病毒（HPV）疫苗接种是预防宫颈癌的有效方法。然而，在日本，HPV疫苗接种覆盖率已降至仅百分之几。反HPV疫苗接种网站经常利用那些有HPV疫苗不良反应经历者的叙述来增强其说服力。学者们建议在网上利用同样的媒介来推广HPV疫苗接种；例如，展示那些有宫颈癌经历者的叙述。我们调查了日本支持和反对HPV疫苗接种网站上使用的叙述数量。方法：我们使用两个主要搜索引擎（谷歌.jp和雅虎.jp）进行在线搜索。根据其主张，将识别出的网站分类为“支持”、“反对”或“中立”。两名独立评分者对支持和反对网站进行编码，并统计有HPV疫苗副作用经历或宫颈癌经历者的叙述数量。结果：总共26%的反对网站发布了关于副作用的叙述。没有支持网站发布关于患宫颈癌的叙述。结论：建议支持HPV疫苗接种的网站发布叙述以增强其论点的说服力。
