title: Trends of Media Coverage on Human Papillomavirus Vaccination in Japanese Newspapers.
abstract: A sensational newspaper article concerning a possible adverse reaction to the human papillomavirus (HPV) vaccine was published in March 2013 in Japan. In June 2013, the Japanese government suspended their proactive recommendation for vaccination, despite the lack of proof for a causal relationship. We searched Nikkei Telecom 21, the largest newspaper database in Japan, for articles published from January 2011 to December 2015 to evaluate the characteristics of newspaper publications about human papillomavirus vaccination. We identified 1138 HPV vaccine-related articles. Compared with those published before March 2013, articles concerning human papillomavirus vaccination after March 2013 were more likely to include adverse reaction-related and authority-related keywords; articles that included efficacy-related keywords decreased significantly. Negative-negative and negative-neutral articles became more frequent, and positive-positive and positive-neutral articles were less frequent. A sensational case report shaped the tone of negative media coverage as a catalyst, regardless of scientific statements from health authorities.
