Abstract: Human immunodeficiency viruses 1 and 2 (HIV-1, 2) present a public health problem for which there is neither an effective antiviral therapy nor a preventive vaccine. In this study, the immune responses of mice to prime-boost vaccination with the recombinant DNA (rDNA) and recombinant Fowlpox virus (rFPV) both expressing HIV-2 Gag-gp105 chimeric protein, were compared to those elicited by each vector alone. Mice primed with the rDNA and boosted with the rFPV showed HIV-2-specific antibody levels, splenic CD4+ and CD8+ T-lymphocyte numbers, and Gag-gp105-specific cytotoxic T-lymphocytes (CTL) activity increased by 20–30% as compared with those elicited by these vaccines alone. These findings suggested that the prime-boost strategy combining rDNA and rFPV elicited significant Gag-gp105 – specific cellular and humoral immune responses, thus supporting this novel approach to the immunization against HIV infections.
