Scientists have managed to turn one of the deadliest insects into a vaccine delivery system. According to new reports from
"Those photos can be seen in the original report and show the results of trial participants being bitten hundreds of times. To get the desired effect of the mosquitos delivering the vaccine, scientists loaded them with genetically modified parasites known as Plasmodium falciparum. In the past, scientists have tried to do something similar. However, this is the first time CRISPR has been used to accomplish it."
"The result is basically 1,000 small flying syringes, a researcher told NPR. And based on the photos featured in that same report, it does look like that, as one image shows a participant’s arm wholly covered in welts from the mosquito bites they suffered. The biggest problem with using mosquitos to deliver vaccines for malaria, though, is the effectiveness."
"Instead, they want to use the mosquitos to deliver vaccines in a more controlled fashion. The researchers told NPR that releasing a massive number of these mosquitos is an intriguing proposition. But, doing so would raise very deep questions about medical consent and bioethics as they couldn’t control who was inoculated and exposed."
