Background information on Aids Vaccine [When available]

In 1984, after the confirmation of the etiological agent of AIDS by Prof. Robert Gallo, the United States Health and Human Services Secretary Margaret Heckler declared that a vaccine would be available within two years (Associated Press, 1984). However, the classical vaccination approaches that have been successful in the control of various viral diseases by priming the adaptive immunity to recognise the viral envelope proteins have failed in the case of HIV-1, as the epitopes of the viral envelope are too variable. Furthermore, the functionally important epitopes of the gp120 protein are masked by glycosylation, trimerisation and receptor-induced conformational changes making it difficult to block with neutralising antibodies. In February 2003, Vaxgen announced that their AIDSVAX vaccine was a failure in North America as there was not a statistically significant reduction of HIV infection within the study population (Francis et al., 2003). In November 2003, it also failed clinical trials in Thailand for the same reason. These vaccines both targeted gp120 and were specific for the geographical regions (Billich et al., 2001).

There are two key issues that protect HIV from vaccines. Firstly, selective pressure quickly neutralised early promise; the falling off of immune response is called anergy. HIV responds rapidly to these pressures, as is recorded by the HIV Variation Project. Secondly, from human isolates it has been discovered that HIV currently has three groups of clades, M, N and O. Nine clades have been identified in M (A-G) but fewer in the others. The earliest vaccine were based on the LAI clade, which was discovered to be rare in human infections. The second problem with HIV is its attack on the immune system itself which means that, to date, no effective cell-mediated immune response has been determined.

Although there have been more than 50 million infections in Africa since 1981, there have been few vaccine trials in the continent, the most severely afflicted by the pandemic. HIV-1 vaccines need to be developed for testing in Africa, as it is in this context, with the risk of infection being the greatest, that a preventative vaccine can be proved to be effective. The remarkable genetic diversity of HIV-1 strains in Africa is a major hurdle in the development of a broadly effective vaccine (McCutchan, 2000). All known HIV-1 subtypes and an array of intersubtype recombinant viruses, often in complex mosaic forms, are found throughout the continent (Peeters and Sharp, 2000). However, the major HIV-1 subtypes accounting for most infections in Africa are subtype C in southern Africa, subtypes A and D in eastern Africa, and CRF02_AG in west-central Africa (UNAIDS, 2004). Therefore, CTL and antibody responses raised by any vaccine need to be broad enough to cover this variability.

The typical animal model for vaccine research is the monkey, often the macaque. The monkeys can be infected with SIV or the chimeric SHIV for research purposes. However, the well-proven route of trying to induce neutralizing antibodies by vaccination has stalled because of the great difficulty in stimulating antibodies that neutralise heterologous primary HIV isolates (Poignard et al., 1999). Some vaccines based on the virus envelope have protected chimpanzees or macaques from homologous virus challenge (Berman et al., 1990), but in clinical trials, individuals who were immunised with similar constructs became infected after later exposure to HIV-1 (Connor et al., 1998).

The human body can defend itself against HIV, as work with monoclonal antibodies (MAb) has proven. That certain individuals can be asymptomatic for decades after infection is encouraging.
