Adjustment for malaria exposure, using a novel molecular measure of [...] subclasses) to merozoite antigens and their relationship to the prospective risk of malaria in children aged 1-4yrs in a malaria endemic region of Papua New Guinea. IgG, IgG1 and IgG3 responses generally increased [...] required for protection from malaria. Our results suggest that in...

RESULTS: Approximately 64% [...] carriers) did not reduce subsequent malaria incidence compared with control areas. CONCLUSIONS: Highly sensitive point-of-care diagnostic tools for detection of all human malaria species are needed to make MSAT [...] BACKGROUND: Seasonal increases in malaria continue in hotspots in...
First results of phase 3 trial of RTS,S/AS01 malaria vaccine in African children (Publications)
vaccination with either RTS,S/AS01 or a non-malaria comparator vaccine. The primary end point of the analysis was vaccine efficacy against clinical malaria during the 12 months after vaccination in the [...] vaccine according to protocol. After 250 children had an episode of severe malaria, we evaluated vaccine efficacy against severe malaria in both age categories. Results In the 14 months after the first dose [...] against severe malaria was 45.1% (95% CI, 23.8 to 60.5) in the...

Malaria infection was via 5 bites of Plasmodium falciparum-infected mosquitos, with individuals reaching patent infection by 11-12 days [...] class switching was seen from an early IgM to an IgG1-dominant response of...
Design of a phase III cluster randomized trial to assess the efficacy and safety of a malaria transmission blocking vaccine (Publications)
falciparum malaria transmission targeting sexual, sporogonic, or mosquito-stage antigens (SSM-VIMT) are currently under development to reduce malaria transmission. An international group of malaria experts [...] estimates suggest that such a trial is feasible, and within the range of previously supported trials of malaria interventions, although substantial issues to implementation exist.
Repurposing of the open access malaria box for kinetoplastid diseases identifies novel active scaffolds against trypanosomatids (Publications)
research using a publicly available screening tool to boost drug discovery. The Malaria Box, assembled by the Medicines for Malaria Venture, is a structurally diverse set of 200 druglike and 200 probelike compounds [...] screening the Malaria Box against a plethora of other parasites would enable the community to better understand the similarities and differences between them. We describe the screening of the Malaria Box and
