Active clinical trials for "Encephalitis"

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 Japanese Encephalitis Chimeric Virus Vaccine (JE-CV) in participants previously vaccinated with JE-CV vaccine. Objectives: To describe JE immune status before and after JE-CV vaccination in subjects previously vaccinated with JE-CV vaccine To describe the immune status before and after 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 vaccine 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.

This is a randomized, open-label Phase 3 study including children aged >9 months to <17 years and 7 months who have been vaccinated with IXIARO in study IC51-323.

To assess the immunogenicity and safety of the vero cell-derived inactivated JE vaccine in Korean healthy children aged 12~23 months

This study is to assess the safety and immunogenicity of three consecutive lots of JE-CV in toddlers aged 12-18 months. Primary objective: To demonstrate the bio-equivalence of three lots of JE-CV vaccine manufactured by sanofi pasteur. Secondary objective: To describe the safety of vaccination in all subjects

The primary objective is to assess the systemic and local safety profile of purified inactivated Japanese Encephalitis Virus (JEV) vaccine IC51 administered in two doses in a 28 days interval up to Month 7 after the first IC51 vaccination in a pediatric population from endemic regions.

The purpose of this study is to determine non-inferiority in seroconversion and to compare the safety and tolerability between ChimeriVaxTM-JE and JE-VAX to the respective homologous virus strain after completion of vaccination course.

The objective is to demonstrate the non-inferiority of the Japanese Encephalitis vaccine IC51 compared to JE-VAX in healthy subjects aged > or = 18 years

The objective is to investigate the safety and tolerability of Japanese Encephalitis vaccine IC51 with an inactive control in healthy subjects aged > or = 18 years

West Nile (WN) virus infection is an emerging disease; WN infection may lead to paralysis, coma, and death. The purpose of this study is to test the safety of and immune response to a WN vaccine in healthy adults. The vaccine is based on a live attenuated vaccine developed against dengue virus.

The purpose of this study is to evaluate a) whether the seroconversion rates in children are equivalent after two and/or three partial vaccinations with TICOVAC 0.25 mL and TICOVAC 0.5 mL, and b) whether there is a difference in terms of safety between the two products.
