Active clinical trials for "Dengue"

The study was designed to evaluate whether the first CYD dengue vaccination can be administered concomitantly with Stamaril® yellow fever vaccine during the same day and visit, but at 2 different sites of administration. Primary Objective: To demonstrate the non-inferiority of the immune response against Yellow Fever (YF) in flavivirus (FV) non-immune subjects at baseline receiving one dose of Stamaril vaccine administered concomitantly with the first dose of CYD dengue vaccine compared to participants receiving one dose of Stamaril vaccine concomitantly with placebo. Secondary Objectives: To assess the non-inferiority of YF immune response 28 days post-Stamaril vaccination based on seroconversion rates regardless of the FV status of participants at baseline. To describe the YF immune response 28 days post-Stamaril vaccination in both groups. To describe the antibody (Ab) response to each dengue virus serotype 28 days post CYD dengue vaccine (Visit [V] 05 and V07), following CYD dengue vaccine Dose 1 and Dose 2 from Group 2 versus following CYD dengue vaccine Dose 2 and Dose 3 for Group 1 (effect of YF vaccination). To describe the safety of Stamaril vaccine administered concomitantly with the first dose of CYD dengue vaccine, or Stamaril administered concomitantly with placebo. To describe the safety of CYD dengue vaccine after the first dose of CYD dengue vaccine administered concomitantly with Stamaril vaccine or CYD vaccine administered alone. To describe the safety of the CYD dengue vaccine in all participants after each dose.

Dengue viruses can cause dengue fever and other more severe forms of disease. This study will evaluate the safety and immune response to two doses of a dengue virus vaccine given 12 months apart in healthy adults.

Dengue viruses can cause dengue fever and other serious health conditions, primarily affecting people living in tropical regions of the world. There are four types of dengue virus, and infection with one does not offer protection against the others. This study will test whether a vaccine developed to prevent infection with dengue virus type 1 (DEN1) causes a response in people's immune system and is safe.

This trial evaluated the use of a tetravalent vaccine against dengue. Primary objectives: To describe the humoral immune response to dengue before and after each vaccination with tetravalent dengue vaccine in adults, adolescents, and children. To evaluate the safety of each vaccination with tetravalent dengue vaccine in the 4 age cohorts. To evaluate the persistence of antibodies against dengue during 5 years after the first vaccination with tetravalent dengue vaccine in the 4 age cohorts.

To evaluate effect of previous flavivirus exposure on the safety and immunogenicity of the ChimeriVax™ dengue tetravalent vaccine Primary Objectives: To describe the safety of one injection of ChimeriVax™ dengue tetravalent vaccine. To describe the immune response against dengue before and after one injection of ChimeriVax™ dengue tetravalent vaccine

Dengue fever, which is caused by dengue viruses, is a major health problem in tropical and subtropical regions of the world. The purpose of this study is to evaluate the safety of and immune response to a new dengue virus vaccine in healthy adults.

This descriptive study will evaluate the safety and immunogenicity of 5 different formulations of the WRAIR dengue vaccine compared to a placebo.

Randomized, double-blind, placebo-controlled, safety, PK/PD and preliminary efficacy study of intravenous IC14 in adult patients in a dengue-endemic region presenting with fever > 38°C for < 48 hours with a positive NS1 strip assay or reverse-transcriptase polymerase chain reaction assay for dengue virus.
