Flyttr Receives Landmark Approval in Brazil for Commercial Production and Deployment of Dengue-fighting Wolbachia Mosquitoes
Approval ushers in professional supply of Wolbachia replacement technology
Unlocks world’s first market for this powerful technology, opening competitive procurement options for public health authorities
No government funds were used in building Flyttr’s Wolbachia factory, the world’s largest, delivering a new capital-efficient model for public health agencies
Campinas, Brazil – July 22, 2026 – Flyttr today announced that Brazil's National Health Surveillance Agency (ANVISA) has granted approval for the production and sale of Flyttr's dengue-blocking Wolbachia-based mosquito solutions in Brazil, marking a significant step forward in the fight against dengue and other mosquito-borne diseases. The decision authorizes the use of Flyttr's Wolbachia for deployment within Brazil's National Arbovirus Control Program, in which municipalities can access Federally provided funds for help combating these deadly threats.
From its Campinas facility, which is the world's largest and most advanced mosquito production factory, Flyttr can produce sufficient Wolbachia mosquito eggs to protect up to 100 million people a year, almost twice the next-largest Wolbachia facility. The scale was built to provide public health authorities and cities across Brazil, Latin America and beyond the ability to source, procure and deploy professional, cost-effective Wolbachia supply at scale.
"Thanks to the Government of Brazil’s leadership, this is a big moment for the global fight against dengue. It represents the first time anywhere in the world where Wolbachia replacement technology is approved for professional commercialization, allowing us to bring the commercial capability of Flyttr’s platform and the efficiencies of industry to drive up supply, drive down cost, and give public health authorities real choices in procurement and deployment,” said Grey Frandsen, CEO of Flyttr. “Universities and governments have led the way in showing this technology is effective; now it’s time for professional commercialization and open markets to move Wolbachia to sustainability. This is our second commercial dengue-fighting mosquito program, joining our innovative Friendly™ Aedes system, resulting in more people protected and more lives saved.”
Wolbachia is a naturally occurring bacterium that, when established in Aedes aegypti mosquitoes, reduces their ability to transmit dengue, Zika, chikungunya and other arboviruses. Because Wolbachia is inherited by offspring, the trait can become self-sustaining in local mosquito populations, reducing the need for repeated interventions over time. The method has been formally recognized by the World Health Organization, and ANVISA's review noted extensive international evidence supporting its safety and effectiveness across more than a dozen countries. In Indonesia, Wolbachia deployments achieved a 77% reduction in dengue incidence and an 86% reduction in hospitalizations.
In Brazil, Flyttr’s Wolbachia platform will support the national government’s dengue control program. Globally, Flyttr can supply governments with bulk egg supply, egg-based deployment devices, adults, and the supporting infrastructure to support the efficient deployment of Wolbachia. In addition, Flyttr offers both the most widely used Wolbachia strain to date, known as wMel, and the more heat-tolerant version, wAlb. The platform also incorporates new, cost-effective monitoring technology, digital deployment planning and AI-powered decision-making, giving cities the intelligence to target interventions where they will have the greatest impact.
"Brazil has long been a leader in developing and adopting innovative approaches to public health," said Dr Natalia Ferreira, Flyttr Brazil’s Managing Director. " Brazil’s research institution Fiocruz has led the way on Wolbachia. Our work is focused on translating Brazil’s leadership in Wolbachia into a future where cost-effective, industry-grade solutions are available for governments to efficiently provide effective dengue prevention to every community in need."
