The experimental vaccine reaches the immune response against HIV / AIDS

Initial tests performed showed encouraging progress after an experimental vaccine tested showed an effective immune response against the HIV virus in humans, a team of researchers reported this weekend.

In a statement in The Lancet, virologist Dan Barouch, director of the study, was very optimistic with the test results. "They represent an important step," he said, although he warned with other experts that there was no guarantee that the following tests were as positive. .

The study concluded, however, that the vaccine is safe and sufficient advanced to initiate a trial in 2,600 women in southern Africa.

Before conducting a human trial, experts tested the vaccine on macaques and were effective in two-thirds of the total sample.

Good results, we tested the drug on a sample of 393 healthy, HIV-free adults aged 18-50 in East Africa, South Africa, Thailand, and the United States. -United.

a placebo, through four injections in 48 weeks. These combinations were made from different types of HIV virus, which became harmless enough, in the hope of getting an immune response.

The tests also concluded that the vaccine is safe for humans. Only five participants reported adverse effects, such as abdominal pain, diarrhea, dizziness or back pain.

In another study, these same vaccines offered protection to two-thirds of the 72 macaques to which researchers were trying to inoculate the virus.

The specialists received the news with optimism. Expert François Venter of the University of the Witwatersrand (South Africa), stressed the "need" to find the definitive vaccine against AIDS.

French Jean-Daniel Lelièvre, of the Vaccine Research Institute, has been shown cautious to study "This is probably not the final vaccine, but it can be a phenomenal breakthrough . " According to him, "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, and every year 1.8 million are diagnosed.

Despite medical advances in the prevention and treatment of the disease, the researchers emphasize the need to find measures to prevent contagion, such as protection during bad, the use of new syringes or equipment of medical sterilization
