Dr. Riko Muranaka is a medical doctor and journalist, WHO consultant and lecturer at the Graduate School of Kyoto University School of Medicine. In October, 2015, Dr. Muranaka jolted the Japanese society believing in the dangers of the HPV vaccine by publishing the article “Did the HPV vaccine really cause these violent fits?’’and re-opened public dialogue about the safety of the HPV vaccination. On Nov.28, 2016, Wall Street Journal published her op-ed Stopping the Spread of Japan’s Antivaccine Panic”. Regardless of the criticism from the anti-vaxxers and a legal attack from the ant-vax doctor, who claimed the dangers of the HPV vaccines by his “one-mouse experiment”, she kept on writing and received the John Maddox Prize in November 2017. This prize is given to the individual who promoted sound science and evidence on a matter of public interest, despite facing difficulty and hostility in doing so. Her story has been widely covered by the major media including the Guardian, BBC, Nature, Financial Times, Vox, Science, the Cell, Der Spiegel and ARD.
