NCT00594958
The objective is to demonstrate equivalence of three IC51 batches in terms of Geometric Mean Titers for anti-JEV neutralizing antibody.
NCT04817917
This study is to evaluate the seroprevalence of neutralizing antibodies against Japanese encephalitis (JE) virus in children aged 6 years who were previously administered with 5 different immunization strategies by JE attenuated live vaccine (JEV-L) or/and inactivated vaccine (JEV-I). The secondary objective is to evaluate the immunogenicity of the booster dose of JEV-I at 6 years old for those previously immunized with 3 doses of JEV-I or those sequential administered with 1 dose of JEV-L and another dose of JEV-I.

The purpose of this study is to describe the immunogenicity and safety of IMOJEV® in adult and pediatric populations in Vietnam and serve a bridging study to compare immunogenicity, reactogenicity, and safety data obtained with IMOJEV® in the Vietnamese population with data from other Asian pediatric populations. Primary objective: \- To describe the safety profile of a single dose of IMOJEV®. Secondary objectives: * To evaluate the immune response to JE 28 days after the administration of a single dose of IMOJEV® in healthy Vietnamese subjects aged from 9 months to 60 years.
NCT03204227
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).
NCT01981967
The aim of this study is to further characterize the safety profile of IMOJEV®. Primary Objective: * To describe serious adverse events (SAEs, including adverse events of special interest \[AESIs\]) up to 60 days after administration of one dose of IMOJEV®. Secondary Objective: * To describe Grade 3 (severe) systemic Adverse Events (AEs) up to 30 minutes after administration of one dose of IMOJEV®.
NCT00735644
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
NCT00596271
The objective is to investigate the immunogenicity of the Japanese Encephalitis vaccine IC51 (JE-PIV) single and concomitant with HAVRIX® 1440
NCT01856205
Japanese encephalitis is caused by a viral infection of the brain transmitted by the bite of an infected mosquito. Patients with Japanese encephalitis can rapidly develop worsening conscious level and seizures. Around a third will die from the infection and half of survivors have serious long-term neurological disability. The majority of those affected are children. There are many causes of viral encephalitis, however Japanese encephalitis virus is the most common cause worldwide with over 60,000 cases annually. It occurs over much of Asia and the geographical range is expanding. There is no specific treatment for Japanese encephalitis virus, although several have been trialed. In this study we examined the effect of a new treatment, called intravenous immunoglobulin, on children with Japanese encephalitis in Nepal. Prior studies have suggested intravenous immunoglobulin may neutralize Japanese encephalitis virus and suppress damaging inflammation in the brain. It has previously been used in individual cases but never examined in a randomized trial. There was recently a trial of IVIG in West Nile encephalitis in the United States, in which Professor Solomon was on the Scientific Advisory Committee. In this study we will look if intravenous immunoglobulin is safe in this context, and that this treatment may alter the way the immune system manages the infection. Therefore, in this pilot study we will test the hypothesis that IVIG can be safely given to children with suspected JE, with no increased risk of serious adverse events compared with placebo. The aim of this proposal is to conduct a pilot safety and tolerability randomized placebo controlled trial of intravenous immunoglobulin (IVIG) in patients with Japanese encephalitis, to explore the relationship between JEV viral load, pro-inflammatory markers called cytokines and blood brain barrier markers, and the effect of IVIG on these relationships.
NCT00314145
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.
NCT01163123
Japanese encephalitis (JE) is one of important zoonotic infectious diseases in Taiwan. JE caused by Japanese encephalitis virus (JEV) which transmitted by Culex tritaeniorhynchus and used swine as amplifying host. Infections leading to overt encephalitis are estimated to be 1 in 1000 cases. Among JE confirmed cases, approximately 25 percent of cases die and 50 percent of the survivals develop permanent neurologic and/or psychiatric sequelae. JEV circulated in Taiwan are belonged to genotype III and the vaccine strain selected from same genotype. Genotype I JEV was first detected in northern Taiwan in 2008 by CDC, and the same genotype JEV were detected in mosquito collected in central Taiwan by our group. In order to study the genotypic shift of JEV in Taiwan areas, and the effects of the replacement of genotype on vaccine, we will conduct the JEV seroepidemiology in Hualien county which was the highest incidence of JEV in Taiwan. The aims of this study were: (1) study the circulating of genotype I JEV in Hualien county; (2) determine the virulence of genotype I JEV in human; (3) differential diagnosis of JEV genotype I or III infection among confirmed cases; (4) measure the cross neutralizing activity, after immunized with genotype III JEV vaccine, against genotype I JEV; (5) determine the age-specific seroprevalence of JEV antibody; (6) estimate the annual risk of infection for JEV.
NCT00694460
This study evaluated the safety and immunogenicity of rabies vaccine and Japanese encephalitis vaccine in toddlers. All children developed adequate immune responses. Rabies vaccination with PCECV did not interfere with the antibody response to Japanese encephalitis vaccine. The rabies vaccine PCECV and Japanese encephalitis vaccine are safe and immunogenic when administered concomitantly to toddlers.
NCT00216268
Japanese encephalitis is the single largest cause of viral encephalitis in the world today. It occurs in yearly post monsoon outbreaks in Uttar Pradesh and other parts of India and south east Asia. There is presently no antiviral drug of proven benefit for this illness and treatment is mostly supportive. The drug Ribavirin is already in the market in use for other indications. It has been found useful in West Nile encephalitis and various hemorrhagic fevers caused by related arboviruses. This is a double blind placebo of Ribavirin in Japanese encephalitis. To the best of our knowledge, this is the first such trial in the world. The study hypothesis is that children treated with ribavirin will be no different from those getting placebo in terms of mortality, length of hospital stay, days to return to consciousness and oral feeds, days to become afebrile and convulsion free and in 3 month sequelae rate.
