Anti-HIV vaccine results look promising

For the first time a vaccine to prevent HIV infection was released and showed promising test results. Statistically the new vaccine may diminish the risk of contracting HIV by 31 % which represents a significant improvement. The study was done by the US military HIV research program and it was conducted in Thailand on more than 16000 participants aged between 18 and 30 all being HIV negative at the beginning of the tests. After three years monitoring, 51 vaccinated people contracted HIV compared to 74 cases in the group who did not receive vaccine. 23 less cases show a step forward but the results exhibit many flaws due to fact that the tests depend on many random conditions even if the subjects were classified as at "medium" risk of getting HIV. The new vaccine is the outcome of a combination of two vaccines which have failed to work previously on their own. The vaccine against HIV is produced by Global Solutions for Infectious Deseases and Sanofi Pasteur and the research was founded by the National Institute of Allergy and Infectious Deseases and the US Army Medical Research and Materiel Command.
