Elaboration of an anti-HIV vaccine is a highly important task because there is a need to arrest or at least to slow-down the rapid spread of AIDS throughout the world. Regrettably, no attempts to create an effective vaccine resulted in success. Nonetheless, the available data contribute to building up the confidence in that the set purpose can be achieved provided extra resources are found for working out a potential anti-HIV vaccine. The paper contains some results of research conducted by the "Vector" Research Center for Virology and Biotechnology in the field of artificial polyepitope immunogens, which could be potential anti-HIV vaccines, and in the field of creating various system for their delivery. The immunogenic properties of the thus obtained vaccine structures were tested on mice BALB/c. The delivery systems were experimentally demonstrated to ensure the induction of specific antibodies against HIV-1, with such anti-bodies having a virus-neutralizing activity; the above systems also induce the cellular immunity.
