全世界都有反对接种疫苗的情绪，日本也不例外。卫生专业人员在网上发布流感疫苗接种信息，鼓励市民主动接种流感疫苗。然而，流感疫苗在日本人口中的覆盖率并不理想。支持和反对流感疫苗接种网站的内容可能有助于读者接受其中一种立场。我们的目标是使用文本挖掘方法来检查网站上频繁出现的支持和反对流感疫苗接种的内容。我们在2017年1月使用两大日本搜索引擎（b谷歌Japan和Yahoo!）日本)。目标网站根据其主张被分类为“赞成”、“反对”或“中立”，作者被分类为“卫生专业人员”、“大众媒体”或“外行”。进行文本挖掘分析，采用卡方检验进行统计分析。在分析的334个网站中，确定了13个内容主题。在支持接种疫苗的网站上出现频率最高的三个内容主题是预防流感重症病例的接种效果、疫苗接种的副作用和疫苗接种的有效率。反疫苗网站上最常见的三个话题是流感疫苗接种的无效、疫苗接种的毒性和疫苗接种的副作用。还揭示了每个专题的主要传播者，按作者分类。我们讨论了在线流感疫苗推广的可能策略，以对抗反疫苗接种网站。
Anti-vaccination sentiment exists worldwide and Japan is no exception. Health professionals publish pro-influenza vaccination messages online to encourage proactive seeking of influenza vaccination. However, influenza vaccine coverage among the Japanese population is less than optimal. The contents of pro- and anti-influenza vaccination websites may contribute to readers’ acceptance of one or the other position. We aimed to use a text-mining method to examine frequently appearing content on websites for and against influenza vaccination. We conducted online searches in January 2017 using two major Japanese search engines (Google Japan and Yahoo! Japan). Targeted websites were classified as ‘pro’, ‘anti’ or ‘neutral’ depending on their claims, with author(s) classified as ‘health professionals’, ‘mass media’ or ‘laypersons’. Text-mining analysis was conducted, and statistical analysis was performed using a chi-squared test. Of the 334 websites analyzed, 13 content topics were identified. The three most frequently appearing content topics on pro-vaccination websites were vaccination effect for preventing serious cases of influenza, side effects of vaccination, and efficacy rate of vaccination. The three most frequent topics on anti-vaccination websites were ineffectiveness of influenza vaccination, toxicity of vaccination, and side effects of vaccination. The main disseminators of each topic, by author classification, were also revealed. We discuss possible tactics of online influenza vaccination promotion to counter anti-vaccination websites.
