Analysis of contamination in cluster randomized trials of malaria interventions (Publications)
BACKGROUND: In cluster randomized trials (CRTs) of interventions against malaria, mosquito movement between households ultimately leads to contamination between intervention and control arms, unless they [...] which contamination measurably biases the estimate of effectiveness. A sigmoid function is fitted to malaria prevalence or incidence data as a function of the distance of households to the intervention boundary
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...
Optimizing malaria vector control in the Greater Mekong Subregion: a systematic review and mathematical modelling study to identify desirable... (Publications)
the daytime and night-time to advance malaria elimination. METHODS: We conducted systematic literature searches to generate a bionomic dataset of the main malaria vectors in the GMS, including human blood
Evaluation of malaria rapid diagnostic test performance and <em>pfhrp2</em> deletion in Tanzania school surveys, 2017 (Publications)
As part of malaria nationwide monitoring and evaluation initiatives, there is an increasing trend of incorporating malaria rapid diagnostic tests (mRDTs) in surveys conducted within primary schools to [...] to detect malaria parasites. However, mRDTs based on the detection of histidine-rich protein 2 (HRP2) are known to yield false-positive results due to persistent antigenemia, and false-negative results may
The effects of climatic and non-climatic factors on malaria mortality at different spatial scales in western Kenya, 2008-2019 (Publications)
relatively small size of the HDSS, there was spatial variation in malaria mortality that peaked every May-June. The rapid decline in malaria mortality was associated with bed nets, and finer spatial scale [...] BACKGROUND: Malaria mortality is influenced by several factors including climatic and environmental factors, interventions, socioeconomic status (SES) and access to health systems. Here, we investigated [...] ed the joint effects of climatic and non-climatic factors on under-five malaria...
Methodological framework for assessing malaria risk associated with climate change in Côte d'Ivoire (Publications)
Malaria is the leading cause of morbidity among children under five years of age and pregnant women in Côte d'Ivoire. We assessed the geographical distribution of its risk in all climatic zones of the [...] main driving components affecting the risk: Hazard, exposure and vulnerability. Considering the malaria impact chain, various variables were identified for each of the risk factors and for each variable [...] or equatorial (tropical transition regime) in the North and the mountainous (humid)...
A review of selective indoor residual spraying for malaria control (Publications)
BACKGROUND: Indoor residual spraying (IRS) is one of the most effective malaria control tools. However, its application has become limited to specific contexts due to the increased costs of IRS products [...] tive spray targeted to particular areas/surfaces of dwellings-has been proposed to maintain the malaria control and resistance-management benefits of IRS while decreasing the costs of the intervention [...] mosquitoes and (2) studies that evaluated the impact of selective spraying on...
Future use-cases of vaccines in malaria control and elimination (Publications)

[...] well as the development and use of new interventions. A malaria vaccine has long been considered a possible new intervention to aid malaria burden reduction. However, after decades of development, only one [...] consider the use-cases and health targets of future malaria vaccines. These must be...
