Evolutionarily conserved T-cell epitopes on FIV for designing an HIV/AIDS vaccine.

This review will discuss the current state of the human HIV-1 vaccine trials including the safety consideration of vaccine composition and difficulties in determining and defining protective immunity and epitopes to HIV-1. Vaccines in animal models of lentivirus infection are compared. In particular, the findings from the prototype FIV vaccine and the HIV-1 protein immunizations studies in cats are discussed, as well as the resulting research regarding a potential HIV-1 vaccine design based on evolutionarily conserved T-cell epitopes.
