A hive of genetically modified mosquitoes effectively vaccinated a human against malaria in a National Institute of Health-funded trial of the insects' ability to innoculate.

Scientists conducting the study held approximately 200 hungry, gene-altered mosquitoes captive in a box.

Human participants placed their arms over the box of mosquitoes, allowing the blood-thirsty insects to feast on their flesh.

Mosquitoes can easily replace traditional injections, contends Dr. Sean Murphy, a researcher who conducted the study.
