However, something needs to be done for all the numbers of people that are currently infected and have not progressed to AIDS. And that's really what this vaccine is aimed for. It's aimed for people that are still well but are infected and the idea is that it's supposedly meant to stop the progression of HIV to AIDS, stop the immuno-suppression and the mechanism of how it does that is that it maintains your viral load very low.\"\u003cbr/\u003e4. Mid shot of a cameraman\u003cbr/\u003e5. SOUNDBITE: (English) Dr Efthyhia Vardas, University of the Witwatersrand, Perinatal HIV Research Unit (PHRU), in Soweto:\u003cbr/\u003e\"Whether or not this vaccine can be used alone or with drug therapy we're not sure of, so it's very early days but this is the idea behind the vaccine. Of course, we know that in South Africa people can access anti-retrovirals once their CD4 counts are very low, below 200 or 200 and below, and I think that that's really late and so this vaccine could possibly offer hope for those individuals before their CD4 counts actually get too low and before they start treatment.\"\u003cbr/\u003e6. Mid shot of the people who attended the briefing \u003cbr/\u003e7. SOUNDBITE: (English) Professor Gavin Churchyard, principle investigator of AURUM Institute\u003cbr/\u003e\"Particularly important for South Africa in that these results show so far that a large proportion of individuals do mount an effective immune response to the vaccine and that the South African participants have an equally good response compared to those from America.\"\u003cbr/\u003e8. Wide of people attending the briefing \u003cbr/\u003e9. SOUNDBITE: (English) Professor Gavin Churchyard, principle investigator of AURUM Institute\u003cbr/\u003e\"This is a milestone but we still have a long way to go. The next step will be to take this trial and evaluate whether it is truly effective in preventing HIV infection and progression to disease now knowing that 70% approximately of individuals who received the vaccine did develop an immune response to the vaccine.\"\u003cbr/\u003e10. Wide of back shot of the press conference\u003cbr/\u003eParallel trials for AIDS vaccines in South Africa look promising but it will be some time before it is known if the vaccines are truly effective in preventing HIV infection and the progression of the disease to AIDS, a press conference in Sandton, Johannesburg, heard on Friday.\u003cbr/\u003eEarly indications are that vaccine trials tailored for global strains had effect against the strain of the virus most prevalent in South Africa allowing individuals to mount an effective immune response to the vaccine.\u003cbr/\u003e\"Preliminary results support continued development of the vaccine to phase two, which is good news,\" said Professor Gavin Churchyard whose field of research involves the HVTN204 vaccine, which is hoped will be a preventative.\u003cbr/\u003e\"It's an important milestone but we still have a long way to go. Unfortunately, it will still take many years to find an effective vaccine but we are on the right path,\" said Churchyard, who works at the Aurum Institute for Health Research, based in North West.\u003cbr/\u003eDr Efthyhia Vardas, from the University of the Witwatersrand's Perinatal HIV Research Unit (PHRU), based at Chris Hani-Baragwanath hospital in Soweto, who has been working on the GTU-Multi HIV B Clave DNA and Adeno-associated vaccines, aimed at being therapeutic, said there were indications that it could keep viral loads under control.\u003cbr/\u003eShe hoped this treatment would help in maintaining CD4 counts and keep HIV infection in a chronic phase.\u003cbr/\u003e\"It's too early to tell whether it could be used alone, or with a drug,\" she said.\u003cbr/\u003eAnother AIDS vaccine researcher, Glenda Gray, who works with Vardas, explained that vaccines should be seen as becoming part of the toolkit aimed at prevention. \u003cbr/\u003eThe other components were abstinence, behaviour and use of condoms.\u003cbr/\u003eMeanwhile, Professor Lynne Morris, from the National Institute for Communicable Diseases, just back from the international Aids Vaccine Conference in Seattle, in the United States, announced that next years conference would be held in Cape Town.\u003cbr/\u003eAll four scientists are linked to the SA AIDS Vaccine Initiative, which co-ordinates research and development in testing HIV vaccines.\u003cbr/\u003eSouth Africa has an estimated 5.4 million people infected with the AIDS virus - the highest in the world. \u003cbr/\u003eAn estimated 900 South Africans die each day of the disease and more than 1,000 are newly infected each day.\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv class='action-container flex
