A cure (or vaccine) for the common cold?

Sounds like a bad idea to me, at least with respect to the vaccine. The body's immune system is like the muscular system in one sense: if it is never stressed, it will fail to develop normally. Fighting off disease is its job, and in a germ-free environment, it may attack the body's own tissues. Given that colds are relatively benign, cold viruses seem like a poor target for this kind of research.
