Healthy volunteers bitten by mosquitoes in malaria experiment

This study gives healthy adults a controlled malaria infection using donated blood containing the P. vivax parasite. Researchers will monitor how the infection develops, how the immune system responds, and whether mosquitoes can pick up the parasite from participants. The goal is to create a safe model for testing future vaccines and treatments. Participants will take chloroquine to clear the infection and will have follow-up visits for three weeks.
