Genetically modified mosquitoes against Malaria

A consortium of researchers and scientists are set to release 10,000 genetically modified mosquitoes in Bana, a village in Western Burkina Faso in a cutting-edge scientific project which is employing biotechnology to tackle one of the biggest killers in Africa. The initiative, being chaperoned by Target Malaria, a not for profit organization made up of scientists from Imperial College in London, is the latest attempt at finding a cost effective and long term solution to a disease that has defied modern medicine.

Malaria kills over 400,000 people globally each year with 70 percent of the cases occurring in children under the age of five, with 90 percent of Malaria caused deaths occurring in Africa. In Burkina Faso for example, over two thirds of children are hospitalised for malaria before their fifth birthday, with the World Health Organization ranking the country second after Mali in prevalence out of 88 countries.

Existing interventions to fight mosquitoes including nets, insecticides, spays and anti-malarial medications have proven counterproductive as the mosquitoes develop resistance and devise ways of biting in places and times when people are not under the net. The World Health Organization has sounded the alarm on what it calls a troubling shift in the trajectory of the disease, where reducing the rate of transmissions and those dying from it had plateaued at the end of 2016.

The new project now seeks an innovative approach to tame mosquito population growth. The well-bred genetically modified mosquitoes are male and sterile. The idea is to ensure that 90 percent of their offspring are also sterile. This will in turn greatly reduce reproduction and population growth while also minimising incidences of Malaria, since only female mosquitoes transmit the disease.

“This decision is a milestone as it is the first approval for field release of genetically modified mosquitoes in Africa and the first for malaria vectors anywhere. The knowledge and experience from this study will serve to inform the development of our next phases of the project towards a sustainable vector control intervention for malaria,” read a section of a statement from Target Media.

Burkina Faso’s government has already given the release of the mosquitoes a clean bill of health after consultations with the locals addressed the concerns they had expressed. The success of the project will inspire scaling it to Ghana, Uganda, Kenya, and Mali, which are considered to also have some of the highest transmission rates in the continent. The organisation is already running outreach programmes in these countries.

In a technology that has always been treated with apprehension, the proponents of the genetically modified mosquitoes are keen to reduce any fears of its dangers to the community. Target Media has already sent a team of independent scientists to carry out an ecological risk assessment to ensure the release doesn’t harm humans or the ecosystem. The organisation is also ensuring there is no backlash from the community as was in Zambia in the 2002 drought when the government rejected 35,000 tonnes of food aid claiming it was genetically modified despite the fact that close to 3 million people were faced with starvation.

The GM mosquitoes project has however faced resistance from some quarters who have dismissed it as irresponsible, with no real benefit in the war on Malaria. They claim that there are likely risks should the male sterile mosquitoes get released in the open, which may include imperfect sex sorting of mosquitoes leading to more voracious biting female mosquitoes or a possible failure of the sterility programme. “Conducting experiments with no potential benefit may be regarded as a waste of time and money. Furthermore, medical research that poses risks but brings no benefits is unethical,” said Lim Li Ching, Senior Researcher from the Third World Network in a terse statement.

Mariam Mayet, Executive Director of the African Centre for Biodiversity added his voice when he said that, “Releasing risky GM mosquitoes into the environment, for absolutely no benefit whatsoever, is completely unacceptable. We call for the application to be immediately withdrawn, or rejected by the authorities in Burkina Faso.”

But while the jury is still out on the efficacy of this project in Burkina Faso, GM modified mosquitoes have previously been used to tackle related cases. In California and Brazil, they were used to in the fight against Zika and Denque, both mosquito born diseases, with studies showing that the genetic mosquitoes reduced the disease carrying mosquito population in a Brazilian neighbourhood by 81 percent.

With the disease on the rise and millions of people’s lives at risk, questions around ethics of genetic engineering are indeed crucial and should be carefully considered. But while this subject is set to dominate discussions for years to come, for the time being, GM mosquitoes flicker a glimpse of hope for the citizens of Burkina Faso.
