Project description: 
In a recent Phase 2a controlled human malaria infection trial, healthy adult volunteers vaccinated with a delayed fractional dose regimen showed a higher vaccine efficacy (86.7%) than those receiving the standard dose regimen (62.5%).
 
The MAL094 study is designed to confirm these CHMI results in people living in malaria-endemic regions in Africa and against natural malaria infections. The study is being conducted at sites in Ghana and Kenya in children aged 5 to 17 months at enrollment.
