Method for producing Japanese encephalitis vaccine that can be stably stored for a long period of time and use of the vaccine

摘要

The inventors of the present invention have improved the inactivation treatment method of the Japanese encephalitis virus vaccine and studied the safety of the vaccine produced by mixing a plurality of vaccines. As a result, we have succeeded in producing a highly safe Japanese encephalitis vaccine that can be stored for a long period of time more stably than conventional Japanese encephalitis vaccines and produced by cell culture. In addition, with other virus vaccines, it is expected that vaccines with good storage stability can be produced by the same production method.
