Immunogenicity of SA 14-14-2 JE Vaccine

Summary

The proposed Japanese Encephalitis (JE)Vaccine study is a four-arm double-blind randomized controlled single center trial to evaluate, by examining post-vaccination seroprotection titers, the lot-to-lot consistency of three lots of JE live attenuated SA 14-14-2 vaccine manufactured in a new GMP facility, and to establish non-inferiority of the new vaccine in comparison to a single lot of the same vaccine manufactured in the existing facility. The study will enroll a total of 1,000 Bangladeshi infants aged 10 to 12 months. In addition to providing immunogenicity data, JEV05 will provide local safety data of JE live attenuated SA 14-14-2 vaccine among Bangladeshi children. This will be the first step to secure licensure for this life-saving vaccine in Bangladesh as well as provide data to support WHO prequalification of JE live attenuated SA 14-14-2 vaccine.
