Um, yeah, they're undead. I'm guessing you haven't played Daggerall, since there's a story in it that goes into great detail of a knight who caught vampirism, died, was buried, and then reborn. The disease kills you. Harkon kills you. You just comeback to life to spite Arkay. Considering literally everyone in game also says your a corpse, the fact that the ritual is called to bring deadflesh back to life, the Soul Cairn recognizes you as dead, and the fact that it involves Molag Bal, all point to the fact that vampirism kills.
