Journal Article 2017 12 14 Background: HPV vaccination is an effective way in preventing cervical cancer. However, HPV vaccination<br />coverage rate has fallen to only a few percent in Japan. Anti HPV-vaccination websites often use narratives of those<br />who have experienced adverse reactions to HPV vaccine to enhance their persuasiveness. Scholars suggest using the<br />same medium to promote HPV vaccination online; e.g., presenting narratives of those who have experienced cervical<br />cancer. We examined the amount of narratives used on Japanese pro- and anti-HPV vaccination websites. Methods: We<br />conducted online searches using two major search engines (Googl.jp and Yahoo!.jp). Identified websites were classified<br />as “pro,” “anti,” or “neutral” depending on their claims. Two independent raters coded the pro and anti websites and<br />counted the number of narratives of people who experienced side effects of HPV vaccine or cervical cancer. Results:<br />A total 26% of anti websites posted narratives on side effects. No pro websites posted narratives about having cervical<br />cancer. Conclusion: Pro-HPV vaccination websites is recommended to post narratives to enhance the persuasiveness<br />of their arguments. https://journal.waocp.org/article_69120_3a6acde24ca02b8cbd6c5ddaa07abd16.pdf
