This trial is conducted in Asia. The aim of this is to investigate the efficacy and safety of activated recombinant human factor VII (rFVIIa) in achieving haemostasis in patients with Dengue haemorrhagic fever (DHF).
The aim of this study is to evaluate the immunogenicity and safety of the CYD dengue vaccine in India adult subjects. Primary Objectives: - To describe the neutralizing antibody response to each dengue virus serotype before the first vaccination and after each vaccination with CYD dengue vaccine in all subjects. - To describe the safety of the CYD dengue vaccine after each dose in all subjects. Secondary Objective: - To detect symptomatic dengue cases occurring at any time in the trial.
The aim of this study was to evaluate the administration of CYD dengue vaccine serotypes (1, 2, 3 and 4) following a compressed schedule in 3 different populations. Primary Objectives: - To describe the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after CYD dengue vaccine Dose 3 in Group 1 (Month [M] 13) and Group 2 (M07), irrespective of whether or not Yellow Fever (YF) vaccine has been previously administered. - To describe the persistence of the humoral immune response to each of the 4 parental dengue virus serotypes 6 months after CYD dengue vaccine Dose 3 in Group 1 (M18) and Group 2 (M12), irrespective of whether or not YF vaccine has been previously administered. Secondary Objective: - To describe the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after CYD dengue vaccine Dose 1 and Dose 2 in Groups 1 and 2, irrespective of whether or not YF vaccine has been previously administered. - To describe the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after CYD dengue Dose 1 in the combined YF-participants in Group 1 (N=60) and Group 2 (N=60), and in Group 3 (N=120). - To describe by FV status at baseline the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after each injection of CYD dengue vaccine in Groups 1, 2, and 3. - To describe the safety profile after each injection of CYD dengue vaccine and/or YF vaccine.
This is a descriptive prospective community-based seroprevalence study. Primary objective: - To determine the prevalence of specific antibodies (immunoglobulin G [IgG]) against dengue in healthy 5 to 10 year-old children in India. Secondary objectives: - To determine the dengue virus serotype (DeNV-1,2,3 and /or 4) specific to the antibodies in positive (IgG) samples - To estimate the prevalence of specific antibodies (IgG) against Japanese encephalitis in healthy 5 to 10 year-old children in India.
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.
A study of dengue in children presenting to outpatient departments of 5 large hospitals in Ho Chi Minh City and Tien Giang province, Viet Nam. Different blood tests are compared at the early stages of dengue fever onset in their ability to accurately and specifically detect children whose dengue will progress to severe disease.
The aim of the study was to assess whether the second CYD dengue vaccination could be administered concomitantly with the booster vaccination of a pediatric combination vaccine (Pentaxim™) during the same day visit but in 2 different sites of administration.
