Development is advanced enough to test it in 2,600 women in southern Africa. Study published in "The Lancet."

The researchers announced Saturday that they tested an experimental vaccine against HIV, which caused a human immune response and protected some monkeys from infection a new finding encouraging.
The development of this potential vaccine, safe for humans, is "These results represent an important step" toward the creation of a vaccine, said the study's director, the virologist Dan Barouch, in a statement. The magazine The Lancet
However, he warned that there is no guarantee that the next tests will be positive. "We must be cautious," he told AFP
Two-thirds of the rhesus macaques who underwent treatment were protected by the vaccine in laboratory tests.
The test results are expected in 2021 or 2022.
This is the "fifth concept vaccine" against HIV tested in 35 years, according to Barouch.
Another, called RV144, showed that he was protecting the HIV man up to a certain point. In 2009, a study indicated that there was a 31.2% reduction in the risk of infection among 16,000 volunteers in Thailand.
The study published Saturday was conducted among 393 healthy, seronegative adults, between 18 and 50 years of age in East Africa, South Africa, Thailand and the United States. -United. Some of them received a placebo
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 advance. "19659005" We are in dire need of a vaccine, "says François Venter of the University of California, Witwatersrand, South Africa, but" we have already known: promising experimental vaccines that do not materialize. "
" This is surely not the definitive vaccine, but it can be a phenomenal breakthrough, "says Jean-Daniel Lelièvre of the Vaccine Research Institute." At best "this research will produce a vaccine that can be administered in "nearly 10 years."
Some 37 million people are living with HIV or AIDS, according to the World Health Organization (WHO) and Health. Millions of people contract it each year.The disease has killed about 35 million of the 80 million it has infected since its first diagnosis in the 1980s.
Despite advances in medicine in prevention and treatment of the disease, (PrEP, antiretrovirals, triterapias), c Herders emphasize the measures to be taken to avoid infection: protection during badual intercourse, use of new syringes, sterilization of medical equipment, etc.
