It’s a shame that you are probably very familiar with Andy Wakefield, Bob Sears, and Del Bigtree, but have never heard of Riko Muranaka.

Do you know any vaccine advocates?
Who is Riko Muranaka?
Riko Muranaka is a doctor and a journalist and was one of the few to push back against all of the negative articles in the Japanese media following the decision of Japanese Ministry of Health, Labour and Welfare to stop formally recommending that girls get vaccinated and protected with the HPV vaccine.
“We can’t afford to sit back and allow a similar situation to develop in which unscientific claims jeopardize lives around the world. The Japanese government should reinstate its proactive recommendation for the HPV vaccine and set a positive example before irrational fear of the vaccine gains further momentum in other countries.”

Not only that, it was her investigation that led to the discovery that the initial report that led to the HPV scare by neurologist Shuichi Ikeda was misleading and inappropriate.
“Evidence she used against Japanese neurologist Shuichi Ikeda revealed that only a single mouse had been vaccinated and the brain section showing damage did not belong to this mouse.”

So where does that leave Riko Muranaka?
In 2017, she received the John Maddox Prize for Standing up for Science “for promoting science and evidence on a matter of public interest, despite facing difficulty or hostility in doing so.”
What kind of difficulty and hostility has she faced?
“Because of her science-based reporting on this topic, Dr. Muranaka experienced massive hostility. Unlike before, she became unable to publish in Japanese media. Her family was threatened, and she was sued by an anti-vaccination doctor.”

Unbelievably, Ikeda sued Dr. Muranaka for defamation and won, even though the Japanese Ministry of Health, Labour and Welfare censured Ikeda for misrepresenting his research. The case is currently on appeal.
And tragically, although HPV vaccines are still available in Japan, after all, they were never banned, they still don’t have a proactive recommendation.
Riko Muranaka still has work to do to get HPV vaccination rates back up in Japan, but she did help to make sure that “Japan’s antivaccine panic” didn’t spread anywhere else.
