According to CNN, estimates have been made by the United Nations and there are about 1.8 million new cases of human immunodeficiency virus (HIV) each year worldwide.
The vaccine provided 67% protection against the virus in monkeys. Although well tolerated by primates, it is unclear whether it offers the same protection to humans. However, the phase was considered successful and ready to be tested in a larger population of patients with a higher risk of infection. The new tests will be conducted with 2,600 women in sub-Saharan Africa.
Some researchers warn that early-stage results do not mean that the vaccine is feasible. The fact that the tested vaccine induces immunity against the virus does not mean that it protects humans from infection.
"I would say that we are satisfied with the data we have obtained so far, but we must interpret them carefully," said Dr. Dan H. Barouch, principal investigator of the study. "We must recognize that the development of an HIV vaccine is an unprecedented challenge and we do not know if this vaccine will protect humans or not," he added.
Carlo del Rio, a doctor of epidemiology, despite not taking part in the study, realized In 2016, more than 5,000 people in South Africa volunteered to participate in tests.
or similar research at the United States Centers for Disease Control and Prevention. "It's a very interesting study, looking for an HIV vaccine is very important," he said.
There is still no cure for AIDS. The only prevention is the use of the condom and avoids any direct contact with the blood.
How does HIV manifest?
The infection is rarely noticeable and is often confused with flu – a short period of fever, headache and throat. In the first 10 to 15 days after infection, the virus begins to invade and destroy the lymphocytes – cells responsible for our defenses – and begins to multiply.
Even if the person infected with HIV shows no signs of illness, she can sexually infect anyone.
During this phase, the body increases the production of cells in the body and tries to eliminate the virus. The duration of each phase depends on the evolution of the virus – on average 8 to 10 years – and the intensity and severity of the infection, the defense capacity of the patient. organism and other diseases that can reduce this defense.
During this time, the patient is HIV-positive, that is to say that the analyzes at this stage can only identify the presence of the virus.
At the end of this silent phase, the defenses of the body deteriorate, the immune system weakens and complications arise, which can be infections by microorganisms, infections by agents more rare or a type of cancer.
