Aids, Vaccine | featured news

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.

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.

What's killing us? For decades, global health leaders have focused on diseases that can spread - AIDS, tuberculosis, new flu bugs. They pushed for vaccines, better treatments and other ways to control germs that were only a plane ride away from seeding outbreaks anywhere in the world....

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.
