Description Skin lesions can be grouped into two categories: primary and secondary. , and infestations of internal organs. The leishmaniases are transmitted by sand flies, blood-feeding insects. The vaccine, which tests show to be effective with mice, utilizes a protein found in sand fly saliva to confer immunity. Further testing is planned on other animals. This research could lead to vaccines for other insect- or tickborne diseases, says institute director Anthony Fauci Anthony S.
