Only "Pureblood" vampires can turn a human into a vampire, by biting them.
The vampires on this show can smell blood, even from quite a distance.
Hanabusa: (caressing the fang marks on Yuki's neck) One day your neck will be touched ever so gently by Lord Kaname's lips . . . And his fangs will slowly pierce through the flesh. When you hear Lord Kaname drinking your blood, you are sure to get a thrill, Yuki.
Hanabusa: (to Yuki) So if Lord Kaname is your savior, then you should be willing to give him every drop of blood in your body.
Yori: (about the bandage on Yuki's neck) Isn't that a deep cut?
Yuki: (embarrassed) Oh, this? I wasn't paying attention during patrols last night and got poked by a tree branch. It's nothing. I'm fine.
Hanabusa:The smell of blood earlier ... We didn't get any sort of explanation after all.
Akatsuki: I'm not interested.
Headmaster: The smell of blood is agitating the Night class.
Kaname: Yuki, are you scared of vampires, now?
Kaname: (to Zero) Was Yuki's blood that delicious?
Kaname: So out of a craving for blood you've turned into a beast, Zero Kiryu. You're a disgrace to vampires.
Headmaster: What's the matter, Kaname?
Kaname: The smell of blood!
