That depends on who wrote the story. In most legends and modern treatments, though, biting a vampire (presumably in the fashion they bite you... to get blood) is part of the transition from victim into Vampire. In the Southern Vampire series, though, Vampire Blood has specific, valuable traits that make it a powerful drug and healing agent.
That often happens in a vampire's case, although they don't intend for that to happen. They prefer the blood to be thick and rich, slowly causing their prey to lose blood.
