Why is there a vaccine for smallpox, but not for HIV?

Websites, especially biochemical, would be great.

Thanks!

There are many HIV vaccines in the works. Whether or not they are effective remains to be seen. The big problem with HIV is that if mutates very quickly.

That is the multi-million dollar question we're trying to solve.

thats a great question, but its still in research, hopefully it will come out one day

because HIV mutates and changes all the time so doctors dont know wat type of medicine will stop it and even if you do get vacinated by it the next day it will have mutated and your vaccine wont be covering the current HIV. so it is very complecated as u can see. hope this helps

When you get a smallpox vaccine, you are actually just being injected with the cowpox virus. The cowpox virus is related to smallpox virus, but is obviously much less severe. The presence of the cowpox virus prevents one from catching smallpox. It was discovered by a man named Jenner who discovered that milkmaids who had cowpox did not catch smallpox.

Unfortunately, no one has yet made any similar breakthroughs regarding HIV, but it is constantly being studied.

There may be one soon. It's called Isenstress developed and manufactured by Merck Pharmaceuticals. Look it up. It blocks the virus from entering cellular DNA, thus replicating.
