Official title
Exploration of Immunologic Mechanisms of Immune Interference and/or Cross-Neutralizing Immunity Following Various Administration Schedules With CYD Tetravalent Dengue Vaccine
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The aim of the study was to evaluate a compressed dosing schedule and the immunologic effects of co-administration of a CYD dengue vaccine with a licensed flavivirus (FV) with Japanese encephalitis (JE) vaccine. Primary Objectives: * To describe and compare the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after each CYD dengue vaccine dose. * To describe the persistence of the humoral immune response to each of the 4 parental dengue virus serotypes 6 after CYD dengue vaccine Dose 3, irrespective of whether or not JE vaccine had been previously administered. Secondary Objectives: * To describe the safety profile after each injection of CYD dengue vaccine. * To describe the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after each CYD dengue vaccine dose when administered with or after JE virus vaccine in Groups 3 and 4. * To describe the persistence of the humoral immune response to each of the 4 parental dengue virus serotypes at 6 months post-dose 3 in all four groups and at 12 months post-dose 3 in Groups 1 and 3 with the compressed schedule. * To determine the level of viremia on Day (D)0, D3, D5, D7 and D14 following each CYD vaccine dose administered in Groups 1-4. * To describe the JE humoral immune response at baseline and 28 days after each injection of CYD dengue vaccine in Groups 3 and 4.
