Is there a vaccine for Japanese Encephalitis?
- Central Research Institute, Kasuali, has developed Japanese encephalitis vaccine indigenously.
- It is a mouse brain killed vaccine and 3 doses are required to produce primary immunization. Two doses are administered sub-cutaneously within a gap of 7-14 days followed by third dose any time after one month and before one year of the second dose. A booster is required after 3 years.
- Mouse brain technology has limitations in huge production beyond a few million.
- Tissue culture vaccines with feasibility of mass production are under various phases of development, standardization and/or commercialization.
