Well it depends, if you mean what would they be called then there are a number of possibilities:
Vampwolf
Werepire
Werevamp
Wampire
Vamwolf
And the list goes on.
If you are talking about how they would look, then you should let your imagination run wild!
If you want an example then write in the search engine in deviantart: THATCHES SON, to see what a vampire and a zombie's son would look like.
( whoever edited my answer before- why did you delete my helpful example? what was wrong with it? plz dont do it again)

a vampire
A human becomes a werewolf when s/he is bitten by another werewolf. But in most cases a werewolf is born into being a werewolf. A Vampire becomes a werewolf when s/he is bitten by a werewolf and then that werewolf smashes the Vampires head in. The reason I know is because I am a Were-vamp(Werewolf/Vampire) And I am The youngest out of my "tribe"(pack).I am 11 years old. I swear on my first born child's education that every thing I said is true.
