I doubt it.
Although it really really needs to be done, and as others have said, you never know what could happen, I know that I am otherwise at a very very low risk of getting it. I'm not an anti-vacine person at all, but I do know enough about genetics and how vaccines work to know that even if it were a relatively safe vaccine, there's not much emergent need for me to take it.
HIV isn't infectious in the way that many diseases with vaccines are. There are more or less only two ways of getting it, and unlike viruses that can be gotten in the air while breathing, it's pretty black and white when you're at risk for contracting it and when you aren't. The most likely circumstance I could envision contracting it is probably getting raped by someone who had it. Which, really isn't that likely either
For people who are at a high risk to get HIV, this will be a wonderful wonderful thing. If my behaviors changed or if I were to move or spend an extended period of time in an area where HIV was particularly widespread I would probably get it.
Also, for the person who mentioned the gardisil vaccine, the vaccine is important not because it simply prevents those couple strains of the HPV virus, but because the strains it prevents are the ones most frequently linked to cervical, anal and throat cancer. Recent studies have found that having one particular strain of HPV is a higher risk factor for throat cancer in men than smoking is. That strain just happens to be one prevented by the vaccine. Thus, it is less about HPV and more about cancer. To call it"Inane" reflects an inane analysis of it's merits.
