Attenuated Chimeric GI/GIII Vaccine Candidate against Japanese Encephalitis Virus.

ABSTRACT: Japanese encephalitis (JE) is a very severe disease characterized by high fatality rates and the development of permanent behavioral, psychiatric, and neurological sequelae among survivors. Japanese encephalitis virus (JEV), a flavivirus, is responsible for JE. In Asia, Genotype I (GI) has emerged as the dominant strain, replacing Genotype III (GIII). However, no clinically approved drug is available to treat JEV infection, and currently available commercial vaccines derived from JEV GIII strains provide only partial protection against GI. Utilizing a reverse genetics system, this study attempted to produce a novel chimeric JEV strain with high efficacy against JEV GI. Accordingly, a GI/GIII intertypic recombinant strain, namely SA14-GI env, was generated by substituting the E region of th
