Neutralising antibodies offers hope for HIV vaccine

Researchers are in the process of discovering the factors responsible for the production of antibodies that do not just fight one virus strain, but neutralises almost all known virus strains.

Researchers develop once-a-week pill to treat HIV

When infected with the HIV virus, humans cannot produce the required antibodies to kill it, which is why an HIV vaccine has been a challenge to develop.

Experimental HIV vaccine is well-tolerated in adults

The new vaccine regimen -- called as "Ad26 mosaic" -- were well-tolerated and capable of generating anti-HIV immune responses in healthy HIV-negative adults.

HIV fight advances with new drug cocktails, fresh vaccine hopes

Researchers believe such advances are necessary to stay ahead of a virus that can all too often develop resistance to medicines, despite the use since 1996 of three- or four-drug combinations that mean HIV/AIDS is no longer a death sentence.

HIV vaccine a step closer? Cows become scientists' aides in developing immunisation!

It is believed that cows evolved a supreme immune defence due to their complex and bacteria-packed digestive system.

HIV vaccine efficacy study begins in South Africa

The new trial, to be conducted at 15 sites across South Africa, where more than 1,000 people become infected with HIV every day, aims to test whether it will provide greater and more sustained protection than the RV144 regimen.

HIV vaccine: Australian scientists achieve step in 'right direction'

A team of researchers from South Australia's University of Adelaide and the Queen Elizabeth Hospital have used a common cold virus to introduce their DNA-based vaccine into the immune system of laboratory mice.

Breakthrough in HIV? Researchers may have found a possible cure for deadly infection

The research, being carried out by five of Britain's top universities with NHS support, is combining standard antiretroviral drugs with a drug that reactivates dormant HIV and a vaccine that induces the immune system to destroy the infected cells.

HIV 'un-canned', paving way for virus transmission-preventing vaccine

A team of researchers has "un-canned" the human immunodeficiency virus (HIV), which is a bit like a hermetically sealed tin can no one has yet been able to break open.

New vaccine can improve HIV treatment

A vaccine has been found to boost a human immunodeficiency virus (HIV)-infected patient's immune system and increase effectiveness of antiretroviral drugs in a phase II clinical trial, researchers have reported.

New compound raises hope for HIV vaccine

In a major step against HIV (human immunodeficiency virus), the virus that causes AIDS, scientists have announced the creation of a novel drug candidate that is so potent and universally effective it might work as part of an unconventional vaccine.

HIV vaccine a step closer

Researchers have uncovered new properties of special HIV antibodies called "broadly neutralising antibodies" or BNAbs, a discovery that could shed light on the pathway the BNAbs take to develop and speed up development of HIV vaccine.

New biomarker discovery brings HIV vaccine a step closer

The vaccine for HIV being developed by the Norwegian vaccine company Bionor Pharma could soon be a reality as researchers have found that median HIV viral load reduction more than doubled among participants with high anti-C5/gp41732-744 antibody levels.
