Are vampires real?

 I'm coming to bite ya. Beware.

No, vampires are not real. If you look it up on Yahoo! it tells you that vampires are "Mythological or folkloric creature".

You do get people who feel they need to drink blood, if that's your only criteria.

Vampire bats are real and they do lap up blood (usually off of grazing cattle up around the shoulder blade) that they bit into.  No different than a Leech.

No, they are not real. Once dead, a person stays dead.

They do exist but not in the movie-view. If you see one - you die.

It depends on your view. Not the type that turn into bats and fly away but there ARE a segment of people who consider themselves vampires and will find WILLING people to draw blood from and drink. So the answer is...Yes.
