NIH finds sand fly saliva may be the key to leishmaniasis vaccine

Researchers at the National Institutes of Health reported that a leishmaniasis vaccine based on sand fly saliva has worked well in monkeys. There is no human vaccine for the disease, which is caused by parasites carried by sand flies. They found that monkeys bitten by uninfected sand flies and those injected with a protein from sand fly saliva showed some immunity to the disease. This suggests that the protein could play a part in leishmaniasis infection and could potentially be a component of a vaccine for human leishmaniasis. Abstract | Read more
