Ross is famous for his discovery of how malaria is transmitted. Ross based his research off of Charles Laveran's, another scientist, observations that the blood of malaria patients contained parasites. In 1894, fellow scientist Sir Patrick Manson suggested that mosquitoes were responsible for transmitting these parasites to humans. August 16, 1897, Ross had ten mosquitoes feed on a malaria patient who had agreed to be volunteer. Ross dissected the mosquitoes after a couple days. When he studied the mosquito's stomach tissue, he found cells too small to be mosquito stomach cells. Inside each cell was a cluster of black granules just like the parasites Laveran found in malaria patients. Ross then concluded that the cause of malaria was mosquitoes. He was awarded the 1902 Nobel Prize in physiology or medicine. This discovery was vital for biochemist Manuel Patarroyo when creating the world's first safe and effective malaria vaccine in 1994.
