Mounting evidence suggests that the early dissemination of HIV in human
beings evokes an immune response that is responsible for containment of
the infection during the long symptom-free period. Loss of this immune
control coincides with a final escalation of the viraemia and the
terminal failure of the immune system. Other studies imply that
pre-emptive vaccination of monkeys with attenuated forms of simian
immunodeficiency virus (SIV) produces a substantial degree of resistance
to superinfection with fully virulent viruses. Here we consider how
observations from natural and experimental systems might influence
thought as to what is required to produce safe induced immunity against
HIV. We concentrate on three questions: what is the nature of the immune
response that contains the infection? How does this response fail? How
could a vaccine enhance protective immunity so that it exceeds the
efficacy of this natural response?
