 While Japanese's Health Ministry stated that Ikeda's results "have not proven anything about whether the symptoms that occurred after HPV vaccination were caused by the HPV vaccine," the court ruled that evidence of fabrication was absent.The university investigation on Ikeda's work concluded that he did not commit scientific misconduct, but that conclusions may have been overstated, then released a statement, including that the research did not conclusively provide a link in relation to vaccine safety.Muranaka lost the slander case.
