Active clinical trials for "Encephalitis"

The study investigates the long term persistence the Japanese encephalitis vaccine IC51 and the need of a booster dose

The study investigates a rapid immunization regime of the Japanese Encephalitis vaccine IC51 (JE-PIV) in healthy subjects aged > or = 18 years

The objective is to demonstrate equivalence of three IC51 batches in terms of Geometric Mean Titers for anti-JEV neutralizing antibody.

The primary objective is to assess the safety profile of IC51 in a pediatric population from regions where JEV is not endemic

The objective of this study is to investigate the immunogenicity and safety of a third vaccination with FSME-IMMUN 0.5 ml given approximately 12 months after the second vaccination in Study 225. In Study 225, two vaccinations were given using a rapid immunization schedule 12 ± 2 days apart.

The purpose of this study is to observe the occurrence of adverse events and seroconversion rate, geometric mean titres (GMTs) of live attenuated varicella vaccine，live attenuated JE vaccine and live attenuated varicella vaccine combined with live attenuated JE vaccine, respectively.

A study of the study vaccine (JECEVAX- VABIOTECH-Vietnam) and a licensed vaccine (JEVAX-VABIOTECH-Vietnam) is conducted in Vietnamese children, aged 9 to 24 months to assess the safety of the study vaccine compares to licenced vaccine. Two hundred and twenty children are enrolled and randomly assigned into 2 groups (110 children/group), each of which receive 2 doses of study / control vaccine subcutaneously, at 28-34 days interval. Safety data included immediate reaction at the injection site and systemic reaction within 30 min of administration, solicited and unsolicited adverse events occurs from the 1st dose to 28-34 days after first dose and from the second dose to 28-34 days after 2nd dose. SAE (from start of first dose to 28-34 days after second dose).

A dose escalating study with 3 different dosing regimens of the studied vaccine (JECEVAX- VABIOTECH-Vietnam) and a licensed vaccine (JEVAX-VABIOTECH-Vietnam) is conducted in Vietnamese children, aged 9 to 24 months to assess the safety and immunogenicity. Two hundred children are enrolled and randomly assigned into 4 groups (50 children/group), each of which receive 2 doses of study / control vaccine subcutaneously, at 10-12 days interval. Safety issues included immediate reaction at the site of injection and systemic reaction within 30 min of administration, solicited and unsolicited adverse events occurs from the first dose to 30 days after second dose; SAE (from start of first dose to 30 days after second dose), blood cell count, urea, ALT, AST. Immunogenicity outcomes include seroconversion of neutralizing antibodies (blood samples are taken prior to 1st dose and 20-22 days post 2nd dose).

This study is being conducted to collect safety and immunogenicity data for the Eastern Equine Encephalitis (EEE) vaccine.

The main purpose of this study is to provide safety and immunogenicity data in Japanese participants.
