Eliminate Dengue Program

Contents

Eliminate Dengue Program is a research initiative founded in 2008 at the University of Queensland by entomologist Scott O'Neill to reduce transmission of dengue fever using Wolbachia bacteria. The program brought together researchers from institutions including the Monash University, the National University of Singapore, the World Mosquito Program, and the Peter Doherty Institute for Infection and Immunity. It coordinated field trials across cities such as Cairns, Townsville, Medellín, Yogyakarta, and Rio de Janeiro while engaging with public health agencies like the World Health Organization, the Pan American Health Organization, the Australian Department of Health, and municipal health departments.

Overview

The initiative originated in laboratories at the University of Melbourne and the University of Queensland following collaborative work between Scott O'Neill, Heather Flores, and teams associated with the CSL Limited and the Wellcome Trust. Early partnerships included the Bill & Melinda Gates Foundation, the National Institutes of Health, the Medical Research Council (UK), and the European Commission. The program aimed to deploy Wolbachia pipientis strains to interfere with viruses transmitted by Aedes aegypti and thereby reduce incidence of dengue, with secondary aims covering Zika virus, chikungunya, and yellow fever. Governance involved coordination with local bodies such as the Queensland Health, Indonesian Ministry of Health, Colombian National Institute of Health, and ethical review boards tied to the University of Oxford and the University of Sydney.

The scientific approach modifies populations of Aedes aegypti through maternal transmission of Wolbachia to create a incompatibility mechanism studied in evolutionary ecology and population genetics by groups linked to the Australian National University, the Rockefeller Foundation, and the Pasteur Institute. Laboratory work drew on techniques from teams at the Johns Hopkins Bloomberg School of Public Health, the Centers for Disease Control and Prevention, the Imperial College London, and the University of Cambridge. Trials tested strains such as wMel and wAlbB developed with input from the Griffith University and the Shanghai Institute of Pasteur, with modeling contributions from the London School of Hygiene & Tropical Medicine and the Fred Hutchinson Cancer Research Center. Entomologists coordinated mass-rearing facilities influenced by protocols from the International Atomic Energy Agency's insect pest control programs and genetic biocontrol work at the Cayman Islands Mosquito Control Laboratory.

Field releases were conducted in diverse settings including Cairns and Townsville in Australia, Yogyakarta and Bali in Indonesia, Tauá-area projects influenced by Brazilian partners in Recife and Rio de Janeiro, and Latin American trials in Medellín and Cali, coordinated with the Colombian Ministry of Health and municipal health secretariats. Collaborations involved universities such as the Universidad de Antioquia, the Universidad Nacional de Colombia, Universidad de São Paulo, and the Federal University of Rio de Janeiro. Outcome analyses were performed using epidemiological frameworks from the World Health Organization and statistical methods promoted by the Institute for Health Metrics and Evaluation and the London School of Economics’s health economics group. Peer-reviewed evaluations appeared in journals with authors affiliated to the New England Journal of Medicine editorial networks, The Lancet collaborator groups, and researchers connected to the Nature Medicine and PLOS Neglected Tropical Diseases communities. Reported results indicated reductions in dengue incidence in treated areas, with supportive modeling from the National Institutes of Health and meta-analyses involving the Cochrane Collaboration.

Governance frameworks referenced institutional review at bodies including the Human Research Ethics Committee (Australia), the Indonesian Ethics Commission, and the Colombian Ethics Committee. Ethical debates referenced precedents from the Nuremberg Code, Declaration of Helsinki, and regulatory practice at the Food and Drug Administration and the European Medicines Agency. Community engagement strategies drew on methods used in public health campaigns by the World Health Organization, vaccination outreach modeled after Gavi, the Vaccine Alliance initiatives, and vector-control communication strategies used by the Centers for Disease Control and Prevention. Stakeholder consultations involved municipal governments such as the Cairns Regional Council, Yogyakarta Special Region Government, and civil society partners including Médecins Sans Frontières affiliates and local NGOs trained with support from the Rockefeller Foundation and the Asia Foundation.

Proponents cited measurable public health impacts comparable to interventions evaluated by the Global Fund and the Bill & Melinda Gates Foundation’s funded projects, while skeptics raised concerns echoed in debates involving the Convention on Biological Diversity and regulators at the European Food Safety Authority. Challenges included scale-up logistics similar to those faced by campaigns of the Pan American Health Organization, intellectual property and licensing issues seen with biotech partnerships involving the National Institutes of Health and private firms, and ecological unknowns referenced by researchers at institutions like the Max Planck Institute for Evolutionary Biology and the Smithsonian Tropical Research Institute. Criticism also invoked case studies from the Release of genetically modified mosquitoes debates in places like the Florida Keys and policy scrutiny resembling hearings before national legislatures such as the Australian Parliament and the Indonesian House of Representatives.
