  • According to UNAIDS there are 40 million people world wide living with HIV/AIDS, and approx 5 million new infections occurred in 2003. Messages of prevention and safe sex are critical, but have not yet been universally successful in stemming the tide of this disease. Therefore the need for an effective HIV vaccine has been recognised in South Africa and, indeed, the rest of the world.
  • It is important to make clear that there is NO successful vaccine available yet – anywhere in the world. Even when there is a vaccine, it is critical that people still practice safe sex. As there can be no guarantee that a vaccine is 100% effective in preventing infection. Today we are talking about PREVENTATIVE vaccines, in other words the HIV vaccine would not be a cure for HIV, but rather offer protection to HIV NEGATIVE people.
