On Buffy the Vampire Slayer how does a human become a vampire?

Answer 1

In different legions vampires only have to bite humans for them to become vamires. In vampire diaries You have to drink the blood of a vampire, die with the blood still in your system and feed on human blood for the transformation to be complete. In True Blood a vampire has to give you there blood, you die and are buried with your master until you raise as a vampire.

Any of this helpful?

Well these are just examples of how a human is transformed to a vampire. But in the real world unfortunately there are no vampires.

Answer 2

After a vampire has sucked the blood of a human, the human must suck the blood of the vampire to become one. "It's like one big sucking-fest." Buffy,Welcome to the Hellmouth.
