The mucosal immune system appears to be a major target of the HIV infection. Therefore, a strong pre-existing anti-HIV immune response in mucosal compartments might be able to prevent HIV infection. Conflicting views regarding the mechanisms of protection at mucosal sites, inferred by the contradictory results of mucosal vaccines in human clinical trials,(More)
Oral vaccines have several attractive features; however, due to several challenges, to date, only a limited number of oral vaccines are licensed. Over the past two decades, several oral vehicle delivery systems have been developed to address these challenges and deliver antigens to the target cells in the mucosal immune system. While the size of vehicle(More)
Despite the extensive efforts towards development of an effective HIV vaccine, major challenges surrounding vaccine design still exist. We have previously developed a unique multivalent HIV-1 candidate vaccine representing hypervariable Gp120 and Gag regions. This candidate vaccine was able to induce a broad cell-mediated immune response in HLA-A2.1 mice(More)
