Monkeys protected from infection – humans also show an immune response
Paris (AFP) – To find a vaccine against the HIV / AIDS virus, scientists have made significant progress. An active substance has produced an immune response in humans and protected monkeys against the infection, said the newspaper "The Lancet" on Saturday. In a second time, the drug will be tested on 2,600 women in South Africa.

"The results are promising, but we must remain cautious," said Dan Barouch Medical Professor of Harvard University AFP. The data did not prove that humans could be protected from HIV by the vaccine.
In a laboratory study, 72 monkeys received an injection of this drug and an HIV-like virus. Two-thirds of the animals were thus fully protected against infection by vaccination.
Barouch and his team also conducted a study of 393 healthy adults aged 18 to 50 from East Africa, South Africa, Thailand, and the United States. United. Part of the group received the active substance, the remaining participants received only one placebo. Professor Barouch said the drug tested "triggered strong immune responses in humans."
In addition, the remedy caused only a few side effects in the participants. Five of them complained of stomach upset and diarrhea. As a result, vaccine research is now ready for the next phase: it will inject 2,600 women in South Africa to see if it can actually prevent AIDS. The results are expected in 2021/2022.
Finding an AIDS vaccine is extremely difficult because the avian influenza virus is highly adaptive. Globally, according to the World Health Organization (WHO), about 37 million people are infected with HIV or already living with AIDS. Each year, about 1.8 million people newly infected with the virus, which destroys the body's immune system. About a million people die each year.
