Sponsor's own description

This is a clinical study to assess the safety of primary, secondary and tertiary blood-stage controlled human Plasmodium falciparum malaria infection of healthy malaria-naïve UK adults, as well as to evaluate any effect of prior exposure to a blood-stage controlled human malaria infection (CHMI) on the parasite multiplication rate. As a secondary objective, the immune response to primary, secondary and tertiary P. falciparum blood-stage infection, as well as gametocytaemia, will also be assessed.
