Leishmania major glycoprotein 63 (lmajgp63) gene was used in this study as DNA vaccine candidates. Gene was inserted into VR1012 plasmid by using standard molecular biology protocols, resulting in preparation of lmajgp63/VR1012 plasmid. Vaccine either used as naked or gold particles coated DNA vaccine in immunization of females Balb/c mice. Animals were immunized at week 0, 2 weeks and 6 weeks. Dermojet needle free injector had been used to deliver gold particles coated DNA vaccine intradermally (I/D) while ordinary needle injection was used to deliver naked vaccine intramuscularly (I/M). Immune response for each vaccinated group were detected, two weeks after the third administration of the vaccines, by estimation of serum concentration of IL-2, IL-4, IL-10 and INF-γ, as well as anti-soluble Leismania antigen (anti-SLA) IgG titer, by ELISA test. The results demonstrated the effectiveness of DNA vaccines in induction immune response comparing to control groups (P
