i know it has to do with the fact that they can find a cure for it but it is constantly evolving...so the cure doesnt work. can anyone give me more information?
thank you!

There probably wont ever be a vaccine, for the same reason that you mentioned. The virus is constantly evolving. In fact, it evolves faster than most viruses.
A person that has HIV actually has many different strains within their body, because the virus keeps evolving even inside of the body. It is evolution in action (even though viruses are technically not alive).
New treatments will probably be targeting viral replication. AZT therapy does just that, but it has a lot of side effects and the virus can evolve resistance.

The HIV virus attaches to the T cells by recongnizing the surface protein CD4. After binding to the T cell, the virus enters the cell by membrane fusion. There, a cDNA copy is made by reverse transcriptase. This enzyme lacks the proofreading property of DNA polymerases, so the errors made by the virus are not corrected. Up to 10 out of 8,000 bases may become mutated. Therefore, the drugs and vaccines scientists come up with to battle the HIV virus cannot bind to the constantly changing viral protiens.

It's a virus. You'll have to study virus' to understand the specifics, because I can't explain them, but there is no cure for any (or most, if I'm forgetting one or two) virus/'. They just run their course. Unfortunately, some like HIV run their course until you die.
Add in that the virus mutates. Now even if you can create a vaccine for the virus, you catch a different strain. The vaccine is useless because your body has the wrong antibodies. They don't recognize this virus. And HIV goes after the most important cells, the Helper T cells, preventing your immune system from fighting off and recognizing other virus'.
It's a super virus. It doesn't kill you - what it does is lowers your immune system's strength, and that kills you in the end.
Hope this helped and gets you to do some more research if it didn't. ^_^0

there are hundreds of ailments that have not have been given any treatment. And if there replaced right into a "basic" treatment, it could have been chanced on. Trillions of dollars in analyze later, and the survival expenses for some cancers are as dismal as they have been 30 years in the past. area of the subject with HIV and maximum cancers is that the cells mutate directly and are proof against distinctive remedies in each and every individual individual. it extremely is why 2 those with the comparable kind of maximum cancers - say breast maximum cancers - can get the comparable chemo scientific care and it will artwork on one individual, yet no longer the different. I disagree with the conspiracy theorists who think of they are withholding the remedies. do no longer you think of that those scientists have kin contributors and friends that are plagued via those ailments? Why does no longer they provide those remedies to their kin? possibly i'm naive, and according to risk i merely can't fathom the concept greed could override a chum's well-being.

The answer is because there is much more money in development of treatments then development of cures or prevention.
For an HIV vaccine, the problems have come mainly because the conserved protein regions are not very good antigens, Vaccines work by exposing the body to antigens. The good antigens on HIV happen to be in highly variable regions of the viral proteins.
There are groups who have promising results using DNA vaccines in high doses from a mixture of several HIV-1 and HIV-2 strains, and making hybrids with SIV, but all of this takes time.
However, basically no one who has health insurance dies as a result of HIV infection anymore.

Well HIV is a type of virus and for any type of virus ur suppost to take antibiotics or drugs to stop the virus from multiplying and spreding or even kill it. But after a while the HIV mutates so what ever stoped its division process has no effect anymore. And then natural selection occurs.

you are correct about it mutating, but when scientists come up with a new medication they also become more resistent to the current ones, making it harder to come up with new medication and a cure

Its a punishment from GOD!!
Heheh
On a lighter note, there are medicines that can relief the pain and prolong the bearer's life. Though its expensive....
And I believe, soon, scientists or researchers may soon find a cure for HIV AIDS!
Slowly but surely..

There are a lot fo diseases they can't find the cure for ... the common cold just being one of them.

$$$$$Money is why. If they put the kind of money into research that they do other things, there probly would be a cure for aids. Money is the main reason behind most things$$
