Does radical cure of asymptomatic <em>Plasmodium falciparum</em> place adults in endemic areas at increased risk of recurrent symptomatic malaria? (Publications)
District (northern Ghana) was radically cured of malaria parasites to study subsequent incidence of malaria infection. During the following 20 weeks of the malaria transmission season, 49% experienced clinical [...] hypothesis that radical cure of P. falciparum enhances the risk and severity of subsequent clinical malaria attacks.
Contribution of influenza immunity and virosomal-formulated synthetic peptide to cellular immune responses in a phase I subunit malaria vaccine trial (Publications)
We have demonstrated recently in a phase Ia clinical trial that synthetic malaria peptides delivered by immuno-potentiating reconstituted influenza virosomes (IRIV) induced long-lived peptide-specific [...] have investigated the cellular immune responses specific for IRIV and the surface bound synthetic malaria peptides tested. After vaccination, in 50% (8/16) of the volunteers at least one positive lympho [...] pre-existing influenza specific T cell responses did not interfere negatively with...
Malaria vaccine candidate: design of a multivalent subunit alpha-helical coiled coil poly-epitope (Publications)
identification of new malaria antigens based on protein structural motifs was previously described. We identified and evaluated the malaria vaccine potential of fragments of several malaria antigens containing [...] (PBMC) of adults living in malaria-endemic areas. Affinity purified antigen-specific human antibodies and sera from P181-immunized mice recognised native proteins on malaria-infected erythrocytes in both [...] antigen-specific human antibodies were at high titers and associated with...
MALVAC 2009: progress and challenges in development of whole organism malaria vaccines for endemic countries, 3-4 June 2009, Dakar, Senegal (Publications)
Research and development into whole organism malaria vaccines is progressing rapidly thanks to the major investments over recent years from several funders, and the commitment and interest of many leading

MAIN RESULTS: IRS versus no IRSStable malaria (entomological inoculation rate (EIR) > 1): In one RCT in Tanzania IRS reduced re-infection with malaria parasites detected [...] CI 72 to 76%).Unstable malaria (EIR < 1): In two RCTs, IRS reduced the incidence rate of all malaria infections;PE 31% in India, and 88% (95% CI 69 to 96%) in Pakistan. By malaria species, IRS also reduced [...] favour of IRS). No difference was found for malaria prevalence or...
Estimation of the sequestered parasite load in severe malaria patients using both host and parasite markers (Publications)
The virulence of the malaria parasite Plasmodium falciparum is due, in part, to its ability to cytoadhere in deep vascular beds. Our inability to quantify the load of sequestered parasites hampers our [...] patterns of peripheral parasite densities in a series of 22 patients with severe Plasmodium falciparum malaria. The markers comprised the host factors: haematocrit, circulating host DNA, sTNF-R75 and parasite
