Phase 3 Study of CHIKV VLP Vaccine Safety and Immune Response in Children Aged 1 to Under 12 Years

What this Trial Is About

Researchers are studying the safety and immune response of the CHIKV VLP vaccine in children aged 1 to under 12 years. This Phase 3 randomized, double-blind, placebo-controlled trial aims to evaluate how well the vaccine works and its safety profile in young children against Chikungunya virus infection. Participants will be randomly assigned to one of four groups two active vaccine groups and two placebo groups. The CHIKV VLP vaccine contains chikungunya virus-like particles combined with an aluminum hydroxide adjuvant. The study includes multiple visits for vaccination and follow-up, with immune responses measured at several time points including Days 15, 22, 183, 366, and 732 after vaccination. Safety is monitored throughout via reports of adverse events and serious events. Children in the study will attend scheduled visits to receive the vaccine or placebo and undergo assessments including blood tests to measure immune response. Researchers will track any side effects from vaccination up to two years after the first dose. The main outcomes focus on immune response by Day 22 and safety events throughout the study. Participants health and adherence to study visits will be closely monitored during the entire trial period, which lasts up to approximately two years.
