It's an extraordinary complex virus, and it's resistant to conventional medicine because it affects and debilitates natural immune systems and the body's way of fighting illness. Almost all medicines if not refinements of immunities from bacteria or chemicals such as penicillin are used to supplement or bolster existing immune systems but these are not effective against HIV.

It is sad when people think that HIV or AIDS is some kind of conspiracy. I have a lot of friends who work in medical research, and they have been racking their brains over this problem for many years. The fastest way for any researcher to become instantly world famous would be for him/her to solve this problem. And someday, someone will.
Why is it so tough?
Vaccines take advantage of the human immune system. Humans develop resistance against diseases after they are exposed to them. So, once you have measles, mumps, whooping cough, etc one time, you can't get them again. That makes it easy to develop a vaccine, All we have to do is get some piece of the disease germ and stick it in people. The people develop a resistance to that piece and when the real germ shows up, the human already has resistance and can fight it off easily.
HIV is a pretty weak virus. It doesnt reproduce very fast and it is so weak that almost anything will kill it - soap, direct contact with any kind of disinfectant, or just drying out. But once it is inside the body, it survives a long time -- Unfortunately one reason why HIV is so widespread is that humans disease resistance doesnt seem to be very much activated by this virus. So people have the germ in them and their bodies don't even try to fight it off. OK, so how are you going to convince the body to resist it? It is a real dilemma for the guys who try to make vaccines. They have tried a whole bunch of different biological tricks to try to get the body to recognize and destroy HIV, but none of them have worked so far. Fortunately for most of us, you can't get HIV unless you come into direct juicy contact with someone who has it. So, don't do that!

HIV is a retrovirus, meaning it's the kind that mutates--a lot. In fact, there was a study that was recently conducted and it said that once inside the body, it changes form, making it into a completely new virus. Our white blood cells, particularly our lymphocytic helper T cells gets attacked first by HIV, rendering killer T cells basically useless because the helper T cells regulate the killer T cells. Without the killer T cells, our immunity lowers and even if we take in medicine that is supposed to help us bring back up the number of white blood cells, HIV 'changes' its form or composition again, so we're back to square one. Once we get HIV, it acts so fast and strong that no medicine created is potent enough to even stop it.
Hope I helped! :)

Give Bush HIV and there will a vaccination in no time.

there is no vacination yet because it attacks helper T cells (I may be wrong), which are the messengers of the immune system. they notice when there are foreign invaders, and then tell your immune system to create antibodies that fight off that specific foreign invader. vaccinations work by injecting a dead or severely weakened version of a disease into the body, so that these helper T cells will notice then and tell the body to create antibodies, but since HIV affects these cells, injecting a weakened version of HIV wont do anything.

There may be, but perhaps the Powers That Be don't want it used yet, therefore eliminating some of the overpopulation in our country, as well as overseas.
Just a thought from the Conspiracy theorist in me

because of antigenic drift - that is the antigen which are targets for vaccine keeps on changing,.

I often wonder that myself... what if it has to do with something more ? What is AIDS? is there such a thing as "aid" in the DEFENSE PROGRAM?
