Limited antigenic diversity of <em>Plasmodium falciparum</em> apical membrane antigen 1 supports the development of effective multi-allele vaccines (Publications)
evasion used by many important pathogens, and presents major challenges in vaccine development. In malaria, many key immune targets and vaccine candidates show substantial polymorphism. However, knowledge [...] falciparum apical membrane antigen 1 (AMA1) is an important target of naturally-acquired antibodies in malaria immunity and a leading vaccine candidate. However, AMA1 has extensive allelic diversity with more [...] single population. Therefore, AMA1 serves as an excellent model to assess...
Ultra-sensitive detection of <em>Plasmodium falciparum</em> by amplification of multi-copy subtelomeric targets (Publications)
qPCR in community surveillance and for monitoring interventions to better describe malaria epidemiology and inform malaria elimination efforts [...] BACKGROUND: Planning and evaluating malaria control strategies relies on accurate definition of parasite prevalence in the population. A large proportion of asymptomatic parasite infections can only be [...] might still remain undetected when absent in the limited blood volume sampled. CONCLUSIONS: Measured malaria prevalence in communities is...

A total of 18.2 million LLINs were delivered at an average [...] through previous initiatives.METHODS: The UCC was coordinated through a unit within the National Malaria Control Programme. Partners were contracted by the MoHSW to implement different activities in co [...] delivery and 17% for campaign associated activities. Preliminary results of...
Attrition, physical integrity and insecticidal activity of long-lasting insecticidal nets in sub-Saharan Africa and modelling of their impact on... (Publications)
and killing effects of LLINs on both susceptible and pyrethroid resistant malaria vectors to estimate the protection against malaria transmission-in terms of vectorial capacity (VC)-provided by each net cohort [...] BACKGROUND: Long-lasting insecticidal nets (LLINs) are the primary malaria prevention and control intervention in many parts of sub-Saharan Africa. While LLINs are expected to last at least 3 years under [...] contributions of these different interrelated factors to durability of...

Indifferent to disease: a qualitative investigation of the reasons why some Papua New Guineans who own mosquito nets choose not to use them (Publications)

Rather, the indifference appeared to be rooted in a lack of fear of malaria infection [...] render individual mosquito net use as easy and as convenient as possible and to promote complementary malaria control strategies where appropriate
Strong off-target antibody reactivity to malarial antigens induced by RTS,S/AS01E vaccination is associated with protection (Publications)
