Association of Host Genetics With Vaccine Efficacy and Study of Immune Correlates of Risk From a Tetravalent Dengue Vaccine

Primary objectives: * To assess how dengue vaccine efficacy varies across participant subgroups regarding polymorphism in human leukocyte antigen (HLA) alleles of interest. * To assess the association between HLA alleles and, serotype-specific neutralization antibody titers and summary neutralization measure in the vaccine and placebo groups. * To assess the association between the polymorphism in HLA alleles of interest and susceptibility to Dengue fever and Dengue Haemorrhagic fever. Secondary objectives: * To assess whether dengue serotype-specific neutralizing antibody titers and associated summary neutralization measure at 28 days post-dose 3 are related to the rate of occurrence of symptomatic Virologically-confirmed dengue infection after post-dose 3 * To evaluate whether the dengue serotype-specific neutralizing antibody and associated summary neutralization measure at 28 days post-dose 3 are related to the level of vaccine efficacy against dengue viruses after post-dose 3.
