Study of Japanese Encephalitis Chimeric Virus Vaccine (JE-CV) in Children Previously Immunized With JE-CV
Protocol No. JEC15
Assessment of the Memory Immune Response, Safety of Japanese Encephalitis Chimeric Virus Vaccine (JE-CV) in Children Previously Immunized With a Single Dose of JE-CV and Long-Term Follow-Up
The aim of the study is to investigate the memory immune response and the yearly persistence of the immunity against Japanese Encephalitis (JE) after vaccination with a new Japanese Encephalitis Chimeric Virus (JE-CV) in participants previously vaccinated with JE-CV.

Biological:Japanese encephalitis chimeric virus; Biological: Varicella vaccine
Study participants who are previously immunized with Japanese Encephalitis Chimeric Virus (JE-CV) vaccine will receive a single dose of the new JE-CV and will be followed up for 5 years for immunogenicity. The control (JE-CV naive) participants will receive either one dose of JE-CV or one dose of varicella vaccine. All participants will be monitored for safety for 6 month post vaccination.
