Class Action of National Compensation for Hepatitis B Infection in Japan
The Japanese government promulgated the Vaccination Law in 1948. According to it, infants and young children under the age of 6 must be vaccinated with hepatitis B vaccine. However, because the shared needles are not expressly prohibited, some of the vaccinated people are infected with hepatitis B; chronic hepatitis are caused in adulthood, and the victims finally filed national compensation lawsuits. The plaintiff and others have filed this lawsuit, because they refused to accept the settlement plan about qualification of compensation. For the claim put forward by the plaintiff, the defendant believed that the period of peremption had passed, despite this, the court pointed certainly out that, because of the hepatitis B vaccine in infants and young childhood, those people are infected with chronic hepatitis B, therefore the starting point of the period of peremption should be the onset of “antigen-negative chronic hepatitis B”. This lawsuit did not exceed the period of peremption, and the settlement amount is 12.5 million Japanese yen.
