Scientists hope that an HIV vaccination could be in sight after tests on hundreds of adults and animals have shown "promising" results.
The vaccine could potentially protect people around the world from the threat of HIV.
New drug testing has prevented two-thirds of monkeys from contracting an HIV-like virus and stimulated an immune system immune response in 400 healthy adults, according to the Lancet study [19659004]. The horizon after "promising" drug test results ” clbad=”img-align-none size-full wp-image-7692196″ data-rewritten=”true”/>
More tests will be needed to determine if the immune response can prevent HIV infection.
Approximately 37 million people worldwide are living with HIV or AIDS, and an estimated 1.8 million new cases each year.
But despite advances in the treatment of HIV, no cure or vaccine against the virus has ever been found.
The drug Prep, or pre-exposure prophylaxis, is effective in preventing HIV infection but, unlike a vaccine, it must be taken regularly, even daily, to prevent the virus from getting infected. ;installed.
It is hoped that the new vaccine will offer much better protection against the almost unlimited number of HIV strains
Only four HIV vaccines have been tested in humans, making this test a "significant milestone According to the scientist who led the study.
But Dan Barouch, professor of medicine at Harvard Medical S Chool, added, "The challenges in the development of an HIV vaccine are unprecedented, and the ability to induce specific HIV immune responses is unheard of. Does not necessarily indicate that a vaccine will protect humans from HIV infection. "
What was the test?

<p> Scientists tested various combinations of mosaic vaccine in people aged 18 to 50 who did not have HIV and were in good health. </p>
<p> participants from the United States, Rwanda, Uganda, South Africa, and Thailand received four vaccines for 48 weeks </p>
<p> All vaccine combinations produced one response anti-HIV immune system and have been shown to be safe. 1965 9002] Scientists also conducted a parallel study where they gave the monkeys vaccine to protect them from simian immunodeficiency virus – an HIV-like virus that infects monkeys. </p>
<p> The combination of mosaic vaccines found to protect 67% of 72 monkeys against disease </p>
<h2> The next step? </h2>
