• Status: Not yet recruiting
• Trial end date: 2025-02-15
• Target enrollment: 0
• Participant gender: All

Summary

The Zambia PCPI study will measure the effect of the parasite genotypes associated with SP resistance on parasite clearance and protection from infection when exposed to SP. The total number of participants is expected to be 600 healthy between 3 to 5 years old who have no symptoms of malaria infection of which 400 children will be assigned to the SP group and 200 to the AS group. The results of this study will allow to measure the effect of the parasite genotypes associated with SP resistance on parasite clearance and protection from infection when exposed to SP.
