My honest opinion:
Orc + Vampire = Meh. Baddass swords, still deterred by daylight. So yes, let them become vampires.
RP - Orcs are far from pure of heart or mind. Being a vampire is just being more brutal and bloodthirsty, not much for an orc.
Dwarf + Vampire = Meh. Baddass axes, still deterred by daylight. So yes, let them become vampires.
RP - Dwarfs live deep below the surface, always in shadows. It's only natural for them to seek out vamprism to make that easier.
Elf + Vampire = Mwahahaha, all shall die by my bow while I hide in the shadows! No, they should not be vampires.
RP - Elves are beings of the forest, pure of heart and clear of mind. They refuse the vampire curse with their entire being.
Undead + Vampire = Mwahahaha, all shall die and none can harm me! No, they should not be vampires.
RP - The dead cannot die twice, nor do they have blood to be sucked or bodies capable of being infected.
Others + Vampire = Various abilities that are generally enhanced by vampirism. No, they should not be vampires.
Other races are too inhuman for the human-originating disease to spread, preventing them from becoming vampires themselves.
My overall vote is no, vampires should remain a human-only thing. It's probably the only non-rp reason humans still exist -_-
