Wolbachia to stop dengue transmission in Vietnam and Indonesia


Project Details

The Eliminate Dengue consortia (www.eliminatedengue.com/program is establishing Wolbachia in Aedes aegypti mosquito populations in South East Asia and Latin America.  Wolbachia durably and stably reduces the ability of mosquitoes to transmit dengue and thus offers a standalone intervention for dengue control. Cameron’s group provides expert leadership in understanding the virus blocking capacity of Wolbachia and the conduct of field trials that will deliver gold-standard evidence of its public health benefits. This work is part supported by NHMRC program funding.

Correlates of immunity

Cameron’s group has developed a novel assay that enables measurement of the potency of monoclonal and polyclonal antibodies to neutralise the infectivity of dengue viruses present in freshly collected viremic blood from patients. With NHMRC support, they are deploying this assay to identify the most potent virus-neutralising human mAbs and their cognate epitopes. These studies will inform vaccine design and correlative assays of immunity.

Virus diversity versus efficacy in phase III vaccine trials (collaboration with Sanofi Pasteur)

In collaboration with Sanofi Pasteur, Cameron’s group is using genomics to assess virus population diversity to understand the performance of the Sanofi Pasteur dengue vaccine candidate, CYD-TDV. They have established a whole genome sequencing platform and analysis pipeline to identify potential antigenic drift in the virus population during and after vaccine trials.

Homotypic dengue human challenge studies

With NHMRC support, Cameron’s group is developing a model of experimental dengue virus challenge of adult volunteers with previously documented histories of dengue virus infection.  The rationale is to enable virological and immunological insights into the characteristics of clinical immunity.
