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. Objectives: - To describe JE immune status before, and after a JE-CV booster dose in subjects previously vaccinated with JE-CV - To describe the immune status before, and immune response following JE-CV vaccination in JE-naïve control subjects. - To describe the safety (in terms of solicited and unsolicited adverse events) of a single dose of JE-CV up to 6 months after the last vaccination. - To describe all related serious adverse events (SAEs) and related deaths from 6 months to 5 years after vaccination in JE-CV-primed subjects.
