The test vaccine against HIV has shown that it operates over a period and decreases at high risk of infection due to promiscuity and drug use.
The study was conducted at 16 thousand young people. In general, the vaccine reduced the risk of infection by a third. Of course, the results did not look like a breakthrough, but the first step in the successful development of this product.
The study provided the important scientific data on how
HIV affects the immune system. This vaccine was a combination of the two other vaccines, which failed the test in 2006. The first of them strengthens immunity, and the second has intensified the reaction to the virus.
ALVAC vaccine contained the mutated bird virus, and vaccine AIDSVAX modified version of the protein on the surface of the virus. The three-year trial showed that 50% of people became ill after vaccination. The level of infection in the placebo group was 74%.
