The HIV virus has proven difficult to fight for a number of reasons. One of them is the fact that the virus mutates quickly. That means that the virus changes at the genetic level, making finding a vaccine that works for all variants of the virus difficult if not impossible, thus far.

Virus without a vaccine?
HIV would be one.
Should all hospital personnel should be vaccinated for HIV.?
There is no available vaccine for the HIV virus.
Is HIV a stable virus can it mutate?
The HIV virus is highly unstable, meaning that it does mutate quickly. That has been part of the dilemma in finding a cure, or even a vaccine against the virus.
Why is it difficult to develop HIV vaccine?
Part of the problem in developing an effective vaccine so far has been the issue of mutation. The HIV virus mutates, or changes, rapidly. What this means for vaccine research and development is that as we are studying the virus and figuring out what will be effective against it, it changes, making whatever we have so far come up with ineffective.
It is difficult to develop vaccine for aids why?
HIV is a RNA virus, which means it goes through lots of mutations. A vaccine depends on some of the same immune responses produced by natural infection to create a "memory" of the virus. For HIV, this is particularly hard because the immune system cannot create broad enough antibodies; an antibody created for one HIV virus might not work for another HIV virus, which most likely would have evolved. Thus, our killer T cells cannot recognize the HIV virus many times, failing to defend our bodies against HIV.
What is a disease-causing virus for which there is no vaccination?
HIV and herpes are two examples of disease-causing viruses for which there is no vaccine.
What antiviral vaccine is able to fight HIV?
There is no vaccine for HIV at this time.
Is there a vacciane for HIV?
No; there is no vaccine for HIV.
Can vacciens prevent hepatitis c and hiv?
ANSWER: Currently, there are NO vaccines that can prevent HIV or the HIV virus, but there AREvaccines that can prevent Hep. C.I hope this will help answer your question!
How does the HIV vaccine help to prevent chickenpox?
There is no commercially available HIV vaccine as of 2014.
How does a modified canarypox virus in a potential AIDS vaccine differ from an HIV virus?
The canarypox vectors have more genes/epitopes that have HIV 'parts'. These are what cause the body to produce antibodies against HIV. So it acts as a type of carrier molecule. This molecule hasn't proven to work yet.
Does bacteria or virus cause HIV?
HIV is a virus.
