No. Vampires in Daggerfell pretty much fed on werewolves.
Also to help the vampire cause, vampires get a boost to there already existing skills, werewolfs are given a set number as morrowind had, so in theory a player with alot of high skills and the extra boost from being a vampire could very well over power, out smart and out class a werewolf, then there is the use of magic that vampires can still use but a person in werewolf form cannot , but the vampire would need to already be quite powerful themselves.
But an average vampire would most likely become a werewolfs lunch in TES
