There isn't any cure just yet for AIDS, but its already made great progress. One in particular, in monkeys, who are responding terrifically to a new AIDS vaccine that consists of genetically altered form of cytomegalovirus (CMW), which prevent infection in 13 of the 24 rhesus macaques exposed to a simian immunodeficiency virus (SIV), the monkey form of HIV.

While monkey HIV isn't HIV, its still good news because of our genetically similar cousins according to the authors of the study that published in Nature. They say, it could "significantly contribute" to a human vaccine.

"CMV is not totally benign, it does cause a number of diseases. If you're giving people something you're not going to be able to get rid of should it cause problems, then that's quite a difficult risk to manage," explains one researcher. "I'm scratching my head how to take this approach into humans."

Its good news altogether, taking one step closer to finding a cure to the deadly disease.  [Nature via BBC]
