Paris –
The researchers announced Friday that they have tested an experimental vaccine against HIV, which has caused an immune response in humans and has protected some monkeys from infection, a new deemed encouraging.
"These results represent an important step" toward creating a vaccine, said study director, virologist Dan Barouch, in a statement in the review. The Lancet
However, he warned that there is no guarantee that the following tests will be positive. "We must be careful," he told AFP .
Two-thirds of Rhesus macaques who received treatment were protected by the vaccine in laboratory tests.
Larger tests are expected in 2021 or 2022.
This is the "fifth HIV vaccine concept" 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 showed that the risk of infection was reduced by 31.2% among 16,000 volunteers in Thailand
. The study was conducted among 393 healthy, seronegative, elderly adults from 18 to 50 years old in East Africa. , South Africa, Thailand and the United States. 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 side effects such as diarrhea or dizziness.
These same vaccines protected two-thirds of them. the 72 macaques that researchers have tried after inoculation of the virus
Some specialists interviewed by AFP have welcomed this advance
"We both need a vaccine, "says François Venter of the University of the 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. "In the best case," these investigations will produce a manageable vaccine in "almost 10 years". (I)
