Safety, immunogenicity and efficacy of PfSPZ vaccine against malaria in infants in western Kenya: a double-blind, randomized, placebo-controlled phase... (Publications)
infection in malaria-naive adults. Preclinical studies show that T cell-mediated immunity is required for protection and is readily induced in humans after vaccination. However, previous malaria exposure can [...] and vaccine efficacy (VE) in adults. We hypothesized that infants with less previous exposure to malaria would have improved immunity and protection. We conducted a multi-arm, randomized, double-blind, [...] tolerability, immunogenicity and efficacy of the PfSPZ Vaccine in infants in a...
Doxycycline responding illnesses in returning travellers with undifferentiated non-malaria fever: a European multicenter prospective cohort study (Publications)
BACKGROUND: Diagnosis of undifferentiated non-malaria fevers (NMF) in returning travellers is a great challenge. Currently, there is no consensus about the use of empirical antibiotics in returning travellers [...] travellers with undifferentiated non-malaria fevers (NMF). Although studies in endemic areas showed that a wide range of pathogens implicated in undifferentiated NMF are treatable with doxycycline, the role [...] should be considered in returning travellers with undifferentiated fever...
Potential opportunities and challenges of deploying next generation sequencing and CRISPR-Cas systems to support diagnostics and surveillance towards... (Publications)
Here we discuss the promise and challenges of NGS and CRISPR-Cas in the context of malaria as Africa moves towards malaria elimination. These innovative tools are urgently needed to strengthen the current [...] current diagnostic and surveillance systems. We discuss ongoing efforts to deploy these tools for malaria detection and molecular surveillance highlighting potential opportunities presented by these innovative [...] current workforce and infrastructure challenges. Overall, these ongoing...
Leveraging mathematical models of disease dynamics and machine learning to improve development of novel malaria interventions (Publications)
targeted reductions in malaria prevalence. METHODS: A mathematical model of malaria transmission dynamics is used to simulate deployment and predict potential impact of new malaria interventions by considering [...] mathematical models of malaria dynamics coupled with machine learning. Our analysis identifies requirements of efficacy, coverage, and duration of effect for five novel malaria interventions to achieve [...] achieve specified health goals. RESULTS: We apply our approach to five malar...
Rethinking human resources and capacity building needs for malaria control and elimination in Africa (Publications)
considerable success in controlling malaria worldwide, progress toward achieving malaria elimination has largely stalled. In particular, strategies to overcome roadblocks in malaria control and elimination in Africa [...] Africa are critical to achieving worldwide malaria elimination goals—this continent carries 94% of the global malaria case burden. To identify key areas for targeted efforts, we combined a comprehensive [...] ve review of current literature with direct feedback gathered from...
Scalable process for high-yield production of PfCyRPA using insect cells for inclusion in a malaria virosome-based vaccine candidate (Publications)
been identified as a promising blood-stage candidate antigen to include in a broadly cross-reactive malaria vaccine. In the last couple of decades, substantial effort has been committed to the development [...] aiming to develop a scalable, high-yield, and high-quality PfCyRPA for inclusion in a virosome-based malaria vaccine candidate. Supplements with antioxidants improved PfCyRPA volumetric titers by 50% when added
Prereferral rectal artesunate and referral completion among children with suspected severe malaria in the Democratic Republic of the Congo, Nigeria... (Publications)
artesunate (RAS) require urgent referral to a health facility where appropriate treatment for severe malaria can be provided. However, the rapid improvement of a child's condition after RAS administration may [...] completion is limited. METHODS: An observational study accompanied the roll-out of RAS in three malaria endemic settings in the Democratic Republic of the Congo (DRC), Nigeria and Uganda. Community health [...] health workers and primary health centres enrolled children under 5 years...
Human behavior, livelihood, and malaria transmission in two sites of Papua New Guinea (Publications)
BACKGROUND: Malaria transmission is currently resurging in Papua New Guinea (PNG). In addition to intervention coverage, social and cultural factors influence changes in epidemiology of malaria in PNG. This [...] in relation to current malaria control efforts. METHODS: A mixed-method design was used in 2 sites in PNG. In-depth interviews, focus group discussions, cross-sectional malaria indicator survey, and population [...] d in adult men. CONCLUSIONS: Our findings highlight the potential of...
New methodological approaches to monitor long lasting insecticidal nets (LLINs) durability for sustained malaria control (Publications)
Long lasting insecticidal nets (LLINs) are the current primary vector control measure to prevent malaria transmission. They function by inhibiting mosquitoes from blood feeding and also killing mosquitoes [...] Resistance) and 2) Holed Net project. The ABCDR project aimed at understanding of bednet durability in malaria endemic countries and factors affecting bednet durability with the main focus of using that information
