Mosquito gene drive cancellation disrupts Africa’s malaria research

The abrupt suspension of an anti-malarial gene drive project in Burkina Faso has disrupted plans by scientists in Uganda working on their own modified mosquitoes. The Target Malaria project was put on hold by Burkina Faso’s government in August. Facilities holding genetically modified mosquitoes were sealed, and all samples ordered to be destroyed. Male mosquitoes released in a village were also neutralised with insecticides. A gene drive sees the release of a modified species with the aim of the modification being passed to the next generation, allowing its frequency to increase rapidly in a population.
The project’s freeze casts doubt on other programmes across Africa. Jonathan Kayondo, principal investigator at Target Malaria Uganda, said scientists had not anticipated the decision. “It’s surprising, because Burkina Faso scientists had gone through all the regulatory approvals and were given the go-ahead. They were not operating illegally.” For Ugandan researchers, the termination threatens to disrupt timelines, reshape field study plans, increase costs, and denies the opportunity to build on data gathered.
Target Malaria is a not-for-profit international research consortium, aiming to develop genetic technologies to reduce populations of malaria-transmitting mosquitoes in Africa. Since 2012, it has operated at the Research Institute in Health Sciences (IRSS) in Bobo Dioulasso, Burkina Faso, with funding from the Gates Foundation. In 20191, the Burkina Faso team had released a small, non-gene-drive strain of genetically modified mosquitoes, whose strains carry useful traits such as reduced fertility. The modifications were not preferentially inherited, and disappear naturally over generations.
