> vaccinate a small portion of high risk people and effectively eradicate the disease
You could remove it as an endemic disease in the US and Europe. In places like South Africa where a third of the population is infected, nothing less that a blanket vaccination campaign would work.
(And of course it is not easy to find out who the high risk people are when both HIV and sexual promiscuity are stigmatised, so you might need to vaccinate everyone anyway to avoid costly errors...)
