Immunogenicity of a JE-CV as a Booster Dose After a Primary Vaccination With SA14-14-2 Vaccine

Japanese Encephalitis

The objective of this study is to measured the Geometric mean titer (GMT) of Japanese Encephalitis neutralizing antibody and proportion of seroprotection among the children who received a booster dose of JE-CV after the first dose of SA14-14-2 vaccine.

Ixiaro as Booster After Mouse-brain Derived Vaccines for Japanese Encephalitis

Japanese Encephalitis

The old mouse brain derived Japanese encephalitis vaccines (MBJEV) have been reported to cause serious adverse effects and are therefore replaced with the novel Ixiaro vaccine. The present study investigates whether vaccinees primed with MBJEV can be boosted with Ixiaro. Travellers receiving Japanese encephalitis vaccines are enrolled for a follow-up of immune responses in four groups: A) primary immunization with BMJEV, B) primary and secondary immunizations with MBJEV, C) primary immunizations with Ixiaro and S) Primary immunization with MBJEV and secondary immunization with Ixiaro. Immune responses are followed with help of serum samples collected before and after vaccination.

Lot-to-lot Consistency Trial of Japanese Encephalitis Live Attenuated SA 14-14-2 Vaccine

Japanese Encephalitis

The proposed study is a four-arm double-blind randomized controlled single center trial to evaluate, by examining post-vaccination seroprotection titers, the lot-to-lot consistency of three lots of Japanese Encephalitis live attenuated SA 14-14-2 vaccine (LJEVac) manufactured in a new good manufacture practice (GMP) facility, and to establish non-inferiority of the new vaccine in comparison to a single lot of the same vaccine manufactured in the existing facility. The study aimed to enroll a total of 1,000 Bangladeshi infants aged 10 to 12 months. In addition to providing immunogenicity data, this study provided local safety data of JE live attenuated SA 14-14-2 vaccine among Bangladeshi children. This is the first step to secure licensure for this life-saving vaccine in Bangladesh as well as provide data to support WHO prequalification of JE live attenuated SA 14-14-2 vaccine.

Study of Live Attenuated ChimeriVax™-Japanese Encephalitis Vaccine

Japanese Encephalitis

The purpose of this study is to assess the safety, tolerability, and immunogenicity of a new formulation of lyophilised ChimeriVax™-JE, given at three dose levels, compared with placebo. Primary Objectives: Safety: To obtain safety and tolerability data for a single subcutaneous vaccination with ChimeriVax™-JE, at three dose levels, in healthy adult volunteers (18-49 years old). Immunogenicity: To obtain data on the antibody response to a single subcutaneous vaccination with ChimeriVax™-JE, at three dose levels, in healthy adult volunteers without prior Japanese encephalitis immunity. To assess the durability of immune response up to 12 months following a single subcutaneous vaccination with ChimeriVax™-JE, at three dose levels.

Evalution of Immunogenicity, Safety and Booster Response of a Rabies Vaccine Administered Concomitantly...

RabiesJapanese Encephalitis1 more

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.
