Scientists have taken an important step towards creating an HIV vaccine

According to research recently published in the Lancet, researchers have made an important breakthrough towards the development of a vaccine to protect against HIV.

Most attempts have failed because the virus is able to mutate rapidly, making most vaccines ineffective.

However, scientists in the United States have created a vaccine that has managed to move to the first stage, with nearly 400 uninfected healthy adults who have developed an immune response to the vaccine.

The study recruited 393 HIV-uninfected adults aged 18-50 in East Africa, South Africa, Thailand, and Thailand. United States.

The Mosaic HIV Vaccine is one of five experimental vaccines that have gone this far since the beginning of the HIV / AIDS epidemic.

But it remains to be seen whether the vaccine will pbad the next step when it will be given to 2,600 women at risk in southern Africa.

Research shows that the experimental vaccine has generated robust immune responses.

"These results represent a milestone," said Professor of Medicine at Harvard Medical School and head of the study, Professor Dan Barouch. "But these results need to be interpreted with caution. The challenges in developing an HIV vaccine are unprecedented, and the ability to induce specific immune responses to HIV does not necessarily indicate that" it is important to know that HIV is an HIV vaccine. a vaccine will protect humans against HIV infection. "

Nearly 37 million people worldwide are living with HIV / AIDS, with about 1.8 million new cases each year.

In the 35 years of the HIV epidemic, only four HIV vaccine concepts have been tested in humans, and only one has provided evidence of protection.
