Mathematical modelling of the impact of expanding levels of malaria control interventions on <em>Plasmodium vivax</em> (Publications)
Plasmodium vivax poses unique challenges for malaria control and elimination, notably the potential for relapses to maintain transmission in the face of drug-based treatment and vector control strategies
The candidate blood-stage malaria vaccine P27A induces a robust humoral response in a fast track to the field phase I trial in exposed and non exposed... (Publications)
The present project aimed at evaluating the safety and immunogenicity of P27A peptide vaccine in malaria non-exposed European and exposed African adults. Methods: This study was designed as a staggered [...] GLA-SE (2.5 or 5mug), or control rabies vaccine (Verorab(R)) were administered intramuscularly to 16 malaria non-exposed and 40 exposed subjects on days 0, 28 and 56. Local and systemic adverse events (AEs) [...] an ADCI dependent mechanism. Incidence of AEs and antibody responses were...
Safety, immunogenicity, and protective efficacy against controlled human malaria infection of<em> Plasmodium falciparum</em> sporozoites vaccine in... (Publications)
We are using controlled human malaria infection (CHMI) by direct venous inoculation (DVI) of cryopreserved, infectious Plasmodium falciparum (Pf) sporozoites (SPZ) (PfSPZ Challenge) to try to reduce time [...] time and costs of developing PfSPZ Vaccine to prevent malaria in Africa. Immunization with five doses at 0, 4, 8, 12, and 20 weeks of 2.7 x 10(5) PfSPZ of PfSPZ Vaccine gave 65% vaccine efficacy (VE) at [...] and controls. Antibody responses to Pf circumsporozoite protein were...
Dramatic decreases of malaria transmission intensities in Ifakara, south-eastern Tanzania since early 2000s (Publications)
000) historically experienced moderate to high malaria transmission, mediated mostly by Anopheles gambiae and Anopheles funestus. In early 2000s, malaria transmission [Plasmodium falciparum entomological [...] outdoors in Katindiuka-ward by HLC), resulting in overall PfEIR of 0.102 ib/p/yr. Nearly 80% of malaria vectors were from Katindiuka and Mlabani wards. Anopheles gambiae densities were higher outdoors [...] Most houses had brick walls and/or iron roofs (> 90%), and 52% had screened...
Outdoor malaria transmission risks and social life: a qualitative study in South-Eastern Tanzania (Publications)
BACKGROUND: Behaviour changes in mosquitoes from indoor to outdoor biting result in continuing risk of malaria from outdoor activities, including routine household activities and occasional social and cultural [...] of various social and cultural gatherings that incidentally expose people to mosquito bites and malaria infection. RESULTS: Religious, cultural and social gatherings involving the wider community are conducted [...] work towards elimination. Focusing on single interventions will not...
Clinical and laboratory predictors of imported malaria in an outpatient setting: an aid to medical decision making in returning travelers with fever (Publications)
had the highest positive likelihood ratio for a diagnosis of malaria (13.6), followed by thrombopenia (11.0). Posttest probabilities for malaria were 85% with enlarged spleen and 82% with thrombopenia. A [...] information exists to guide clinicians for giving presumptive treatment to returning travelers when malaria is strongly suspected on clinical grounds but laboratory confirmation is not immediately available [...] laboratory predictors of Plasmodium parasitemia. A total of 336...
