You are confusing fact with fiction.
Vampires are entirely fictional creatures. What they may or may not eat or drink is controlled by the author of the story.
Drinking blood.
Drinking animal blood is vegetarianism but drinking human blood would violate it for vampires.

Most vampires do not kill their victims. Why should they deprive themselves of a food source. Their are even vampires that keep humans as 'Thralls' so that they may have a dependable and trouble-free food source. Vampires dont kill to survive. The blood they need is a ridiculously small amount for someone to die.
In vampire lore, blood in vampires is typically depicted as circulating due to magical or supernatural means rather than through a biological circulatory system like in humans. The concept of blood flow in vampires is often attributed to their undead nature and their ability to regenerate or sustain themselves on blood.
