What would happen to a vampire if they get wounded?

it depends which vampiros from which book,movie gandre r u talkin about
Interview with a vampire-it bleed the victims blood ,but only weakens,not dies;so its what we call dormant.
twilight-it bleeds ,but can heal quickly;with time,can kill them por ripping them apart and burning them(remember in eclipse Valeries little helper could still move, but his arm was of and it could mover on its own.)
Blade- they bleed,they heal quickly, but it depends on how "old" they r otherwise it takes time.
So basicly its different for all our Vamp bro's out there
P.S if they are weak they cant use their xtra powers.
hope this helps

My guess is that they take time to heal.

But proberly blood come out.Or they dont get wounded like no mark
