Can Vampires turn back into humans for good?

Some people will tell you yes to this question but they are getting Lycans and Vampires confused. A vampire cannot turn a human into a vampire simply by biting them. Their fangs are used only to pierce the skin to release their victims blood so that they can feed. To turn a human into a vampire the vampire must first drink or drain much of the human blood out of their victim. Then the victim has to drink some of the vampire's blood. This is the only way to get the vampire virus into a humans system. It then spreads throughout their body turning them into a vampire.
