A research team in the United States is making promising progress in its fight against the HIV virus.In the laboratory, monkeys can be successfully protected against pathogens. But even in humans, the vaccine triggers a strong immune response.
Scientists have made significant progress in the search for an HIV vaccine for the AIDS virus. An active substance has produced an immune response in humans and protected the monkeys from infection, reports the newspaper "The Lancet". The next step will be to test the drug on 2,600 women in South Africa.
"The results are promising, but we have to be careful," said Professor Harvard, professor of medicine Dan Barouch. The data did not prove that humans could also be protected from HIV by the vaccine.
In a laboratory study, 72 monkeys received an injection of this drug and a virus similar to HIV. Two-thirds of the animals were thus fully protected against infection by the vaccine.
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 that the drug tested "triggered strong immune responses in humans."
1.8 million new infections per year
In addition, the remedy Triggered only a few side effects. complained of stomach upset and diarrhea, dizziness or back pain. 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. According to the World Health Organization, about 37 million people worldwide 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 one million people die each year from its consequences.
