Vaccine development in the reservoir host, the domestic dog, is a current research priority. The aim of this study was to conduct safety trial of gentamicin-attenuated L. infantum (L. infantum H-line) in dogs in the endemic area of Southeast Iran. The household dogs were vaccinated subcutaneously with L. infantum H-line. The prospective incidence of natural infection by this vaccine was assessed during a two-year follow up period. The number of animals vaccinated and non-treated control groups was 70 and 50 respectively. The safety of the vaccine on the interruption of the endemic area transmission of the disease was assessed by monitoring the clinical signs and measuring the serum specific anti-Leishmania IgG. No clinical signs of disease including anorexia, apathy, local swelling on injection site, vomiting and diarrhea were developed or observed after the vaccine injection. Therefore, our gentamicin-attenuated L. infantum vaccine induced a significant and strong protective effect against canine leishmaniasis and the consequent transmission to human in the field.
