Filter by: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.
The primary objective of the study was to assess the efficacy of CYD dengue vaccine after three injections in preventing symptomatic virologically-confirmed dengue (VCD) cases, regardless of the severity, due to any of the four serotypes in children aged 4 to 11 years at the time of inclusion. Secondary objectives included to assess: - Vaccine efficacy against severe VCD cases - Vaccine efficacy against VCD cases following at least two injections with CYD dengue vaccine - Immune response to CYD dengue vaccine - Safety profile of CYD dengue vaccine. Safety assessments include solicited reactions within 7 or 14 days after each injection, unsolicited adverse events within 28 days after each injection, and serious adverse events during the study period. Other objectives included: - Vaccine efficacy against VCD cases following at least one injection with CYD dengue vaccine - Vaccine efficacy against VCD cases due to each serotype - Participants with clinical signs and symptoms for VCD
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 test the safety of and immune response to a new dengue virus vaccine in healthy adults.
The aim of the trial was to evaluate the use of a tetravalent vaccine, CYD dengue vaccine, against dengue disease. Primary Objectives: - To describe the humoral immune response to dengue before and after each vaccination with dengue vaccine in two age cohorts of children (6 to 11 years and 2 to 5 years) previously vaccinated with yellow fever (YF) vaccine. - To evaluate the safety of each vaccination with dengue vaccine in two age cohorts of children (6 to 11 years and 2 to 5 years). - To describe viremia after the first and second vaccinations with dengue vaccine in a subgroup of 130 randomized participants (100 participants in Dengue Vaccine Group and 30 participants in Control Group) in two age cohorts of children (6 to 11 years and 2 to 5 years).
This is part of an ongoing effort to develop a satisfactory dengue vaccine: Primary objective: To describe the safety after each vaccination with bivalent and tetravalent formulations of dengue vaccine candidates. To describe the immune response after each vaccination of dengue vaccine.
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
This study used 3 different formulations of tetravalent CYD dengue vaccine. The primary objective of the study was to evaluate the neutralizing antibody response after 2 doses of two different formulations of tetravalent dengue vaccine administered at Month 0 and Month 6. The secondary objectives were: - To evaluate the safety of the 3 formulations of tetravalent CYD dengue vaccine. - To describe the neutralizing antibody responses to each of the 3 vaccine formulations. - To describe vaccine viremia after the first and second dose of each of the 3 vaccine formulations in a subset of participants.
The purpose of this study is to evaluate the safety and effectiveness of two different formulations of an investigational dengue vaccine (T-DEN) against a placebo vaccine when two doses are given six months apart to adults and children.
To assess the safety, reactogenicity and immunogenicity of two doses of the dengue vaccine in Flavi-virus antibody-naive children between 6 and 9 years of age.
