Although the virus has been recolonized for more than 35 years, no efficient vaccine or drugs were invented. That was because the desease has been occered in a limited area, so pharmaceutical companies though they could not get enough profits from the vaccine or drugs.
But now, the situation has been changed. The virus is traveling to many countries now. It's obvious the desease would be found in Japan sooner or later.
I believe scientists and pharmaceutical companies have the potential to invent anti virus production. They need to accelerate that development for helping people.
