(Caracas, July 06, 2012) – Researchers reported testing an experimental HIV vaccine that elicited an immune response between humans and protected certain monkeys of the infection, information considered encouraging
The development of this potential vaccine, safe for humans, is sufficiently advanced to be tested in 2,600 women in southern Africa.
" These results represent an important step" toward the creation of a vaccine said study director, virologist Dan Barouch, in a statement in The Lancet.
However, he warned that there is no guarantee that the following tests will be positive "We must be cautious," he told AFP
The two-thirds Rhesus macaques who underwent treatment were protected by the vaccine in laboratory tests.
The largest tests are expected in 2021 or 2022.
It is the "fifth concept of vaccine against HIV tested in 35 years according to Barouch.
Another, called RV144, has shown that it protects humans from HIV to some extent.In 2009, a study showed that the risk of infection was reduced by 31.2% among 16,000 volunteers in Thailand [19659004] The study published Saturday was conducted among 393 healthy, seronegative adults, between 18 and 50 years of age in East Africa, South Africa in Thailand and the United States. Some of them received a placebo
The tests showed the safety of the vaccine combination, which included different types of HIV virus, with only five participants having adverse effects such as diarrhea or diarrhea. dizziness

Some specialists interviewed by AFP welcomed this progress.
"We both need a vaccine," says François Venter of the University of California. Witwatersrand (South Africa). But " we already knew this: promising experimental vaccines that do not materialize."
"Surely this is not the definitive vaccine, but it can be a phenomenal advance," says Jean-Daniel Lelièvre. Vaccine Research Institute. "At best" these surveys will produce a vaccine that can be administered in "almost 10 years."
About 3 7 million people are living with HIV or AIDS, according to the World Health Organization (WHO). WHO), and 1.8 million people contract it each year . The disease has killed about 35 million of the 80 million that it has infected since its first diagnosis in the 1980s.
Despite advances in medicine in the prevention and treatment of the disease, (PrEP, antiretrovirals , triterapias), the researchers insist on measures to be taken to avoid infection: protection during sex, use of new syringes, sterilization of medical equipment, etc.
