LOL!
The article doesn't say how the vaccine was created, nor exactly how it works.
As I understand it, there are two problems with HIV vaccines.
One is, it appears that merely stimulating the production of antibodies to HIV isn't enough to protect against infection. Your body defends itself against invaders in two different ways: one, it produces antibodies which attach to an invader and disable it; and two, it produces white blood cells which hunt down the invader and eat it. Researchers believe, partly from unsuccessful vaccines, that creating a vaccine that only triggers the antibody response is not enough to protect against HIV. You must have a vaccine that triggers the cell-based response. The cell-based response is active on mucus membranes where the virus would infect its victim.
The other problem with HIV vaccines is the extreme variability of the virus. It quickly forms new strains in a person's body, and this evades the immune system. This is part of the reason why it takes years to develop AIDS after getting infected with HIV -- the virus doesn't lie dormant, instead, the body is in a pitched battle with it for years, a battle it loses because the virus damages the immune system itself. A vaccine must target less variable portions of HIV or its genes; or a variety of subtypes of HIV must be included in the vaccine.
It would be good news indeed if the Indians have produced a successful vaccine. But they haven't begun human trials yet, and there's many a slip twixt the cup and the lips. There are various Western vaccines beginning human trials. But it will be years either way before there's a vaccine, and as aruanan suggests, even then it will still be too dangerous to ignore God's instructions about sexual hygiene.
You forgot poison ivy.
