Aids, Aids Vaccine | featured news

By tracking one patient’s immune response, scientists have tracked how a series of mutations led to an antibody that can defeat many H.I.V. strains.

Science now has the tools to slash the spread of HIV even without a vaccine — and the U.S. is donating an extra $150 million to help poor countries put them in place, the Obama administration told the world's largest AIDS conference Monday.

There are no scientific reasons the world can't chart a path, albeit a difficult one, toward the world's first AIDS-free generation, a top federal health official said Sunday. "There is no excuse scientifically to say we cannot do it," said Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, speaking to the media at AIDS 2012, an international AIDS conference, which began here Sunday. "What we need now is the political and organizational will to implement what science has given us."

The Food and Drug Administration on Monday approved the first drug shown to reduce the risk of HIV infection, the latest milestone in the 30-year battle against the virus that causes AIDS....

Nabel said no vaccine being tested today "is likely to hit it out of the park," but many researchers do feel advances in broadly neutralizing antibodies are key to developing a highly successful HIV vaccine. "It's really a new day when we start to think about where we are with AIDS vaccines," Nabel said.

A new vaccine can protect macaques against the monkey equivalent of HIV and could provide a fresh approach to an HIV vaccine, a study suggests.

The latest research puts scientists much closer to finding a HIV vaccine.

Another look at data from the Thai AIDS vaccine trial shows results are not statistically significant and could have come about merely by chance, a report in the New England Journal of Medicine says.

A secondary analysis of data from the Thai AIDS vaccine trial -- announced last month to much acclaim -- suggests that the vaccine might provide some protection against the virus, but that the results are not statistically significant.

For the first time, an experimental vaccine has prevented infection with the AIDS virus, a watershed event in the deadly epidemic and a surprising result. Recent failures led many scientists to think such a vaccine might never be possible.
