[Spider-Man] Spider-Man's radioactive blood was able to cure him of vampirism in mere hours - but at the same time he's had colds and flus that have lasted for days. Does this mean the colds and flus are stronger?

What it likely means is that the biological base for vampirism is much more complex than a virus. Viruses are very resistant to radiation because they are small and very simple.

See, radiation damages cells when a particle of radiation happens to impact part of the genetic code. Viruses are small and simple enough, and have little redundant bits of code, that they don't get hit often, and when they do it often doesn't destroy them. 

Large, complex cells, like bacteria, or whatever transmits vampirism, will get hit much more often, and an error in their code  can be much worse because of all the processes that interact and depend on each other.
