Cost/benefit analysis and adaptability.
HIV is a remarkably diverse pathogen, which is why it is what it is.
There are dozens of viruses that cause the common cold and they are not life-threatening. R&D on that many vaccines doesn't make much economic sense and doesn't add much in the way of productivity or years-gained to the public.
Viruses that targe the upper respiratory system initially (like this one) are harder to engineer a vaccine for due to the nature of the immune response in that part of the body.
