Gates-Backed Researchers Develop Mosquito 'Flying Syringes'

In a groundbreaking yet controversial development, researchers backed by the Bill and Melinda Gates Foundation have unveiled a novel method of malaria vaccination: genetically modified mosquitoes acting as "flying syringes," Breitbart reported.

Scientists at Leiden University Medical Center in the Netherlands developed the method, via which mosquitoes deliver modified malaria parasites directly into the human bloodstream, according to a study published in the New England Journal of Medicine.

The research involved altering malaria parasites so that they stopped developing at a certain stage. This effectively taught the immune system to recognize and fight the disease without causing a full-blown infection. The modified parasites, named GA1 and GA2, were introduced into mosquitoes, which were then used to deliver the vaccine to human test subjects via bites.

In a controlled trial, 43 healthy adults ages 19 to 35 with no prior history of malaria were split into three groups. Two groups received 50 mosquito bites each from insects infected with either GA1 or GA2 parasites, while the third group received bites from uninfected mosquitoes as a placebo. The participants underwent three vaccination sessions spaced 28 days apart.

After the final session, participants were deliberately exposed to malaria through bites from infected mosquitoes. Results showed that 8 in 9 participants in the GA2 group were effectively protected, compared to just 1 in 8 in the GA1 group and none in the placebo group.

For years, the concept of mosquitoes as "flying vaccinators" has been explored. In 2010, Japanese scientist Shigeto Yoshida demonstrated the potential for insect saliva to deliver vaccines to mice.

Proponents argue that this method could be painless and cost-effective. However, the approach raises ethical concerns, including issues of informed consent and medical safety.

Using genetically modified mosquitoes in human trials has reignited debates around the ethics of such experimental approaches. While the Bill and Melinda Gates Foundation's involvement underscores the potential for large-scale application, critics question the long-term safety and implications of using living organisms as vaccine carriers.

As discussions about the practicality and morality of such methods continue, the research marks a significant milestone in the ongoing fight against malaria, which kills hundreds of thousands of people annually.
