Malaria vaccines: from the laboratory to the field (Publications)
cure of malaria patients with passive transfer of specific immunoglobulins, and iii) protection conferred by vaccination with sporozoites attenuated by radiation, justifies the search for a malaria vaccine [...] include recombinant proteins, synthetic peptides and DNA vaccines, the relevant genes encoding malaria antigens being inserted into a plasmid or a live vector such as vaccinia or poxvirus. A number of [...] Combination B) had an efficacy of 62% in reducing parasite density in Papua New...
Multiplex real-time PCR for the diagnosis of malaria: correlation with microscopy (Publications)
Abstract Malaria is generally diagnosed by microscopy and rapid antigen testing. Molecular methods become more widely used. In the present study, the contribution of a quantitative multiplex malaria PCR was
Participatory mapping of target areas to enable operational larval source management to suppress malaria vector mosquitoes in Dar es Salaam, Tanzania (Publications)
Half of the population of Africa will soon live in towns and cities where it can be protected from malaria by controlling aquatic stages of mosquitoes. Rigorous but affordable and scaleable methods for mapping [...] identification and inclusion of these key areas, as well as more equal distribution of the workload of malaria control field staff. CONCLUSIONS: The procedure developed enables complete coverage of targeted areas [...] affordable, and requires minimal technical skills. This approach...
Malaria vaccines: a toy for travelers or a tool for eradication? (Publications)
efficacy of two candidate malaria vaccines in children living in malaria-endemic areas, namely RTS,S from the circumsporozoite protein that reduced infection and clinical malaria in Mozambique, and an asexual [...] visiting malaria-endemic areas, the usefulness of the first generation of malaria vaccine(s) will be limited, since the level of protection that is foreseen is unlikely to achieve that of malaria chemop [...] reduced parasite density in Papua New Guinea, allows one to believe that a m...
Humoral immune responses during a malaria vaccine trial in Tanzanian infants (Publications)
The development of a malaria vaccine is a priority for improved and sustained malaria control. Optimal use of a vaccine in Africa will only be achieved if it can be delivered through the Expanded Programme [...] preimmunization levels by 2 years of age and which was not associated with protection against clinical malaria. The vaccine induced no IgG antibodies against (NANP)50 or P. falciparum lysates. SPf66 stimulated
Comparative cost models of a liquid nitrogen vapor phase (LNVP) cold chain-distributed cryopreserved malaria vaccine vs. a conventional vaccine (Publications)
the costs and compare these costs to those that would be incurred in distributing a 'conventional' malaria vaccine through the EPI. Capital and recurrent costs for storage, transportation, labor, energy usage
Randomized double-blind controlled Phase I/IIa trial to assess the efficacy of malaria vaccine PfCS102 to protect against challenge with <em>P.... (Publications)
this Phase I/IIa double-blind controlled trial was to test the efficacy of the sporozoite-based malaria vaccine PfCS 282-383 (PfCS102) to protect against Plasmodium falciparum parasitaemia. 16 volunteers [...] antibodies against PfCS102 versus none control. 8/8 vaccinees and 6/6 controls challenged developed malaria parasitaemia. The duration from infection to onset of patent parasitaemia was similar in both groups
A simulation model of African Anopheles ecology and population dynamics for the analysis of malaria transmission (Publications)
BACKGROUND: Malaria is one of the oldest and deadliest infectious diseases in humans. Many mathematical models of malaria have been developed during the past century, and applied to potential interventions [...] However, malaria remains uncontrolled and is increasing in many areas, as are vector and parasite resistance to insecticides and drugs. METHODS: This study presents a simulation model of African malaria vectors
