And they won't have even been bitten. Well, the truth is, they won't be an actual vampire but they'll mimic some of the characteristics of one without being dead by virtue of a very rare disease called porphyria AKA the 'Dracula' disease. Sufferers of porphyria only have the symptoms of a vampire's weakness, so instead of it giving you super speed, strength and the ability to transform into a bat, you're only really sensitive to sunlight and you might suffer from paranoia to the point where you'll eventually go mad. You won't have any addictions or cravings for blood although there is a chance that your teeth might become stained so it might give off the impression that you do. There are also genuinely people out there who do have cravings for blood, and there is a fetish culture where willing participants lick the open wound of another person or just drinks blood straight from the bottle.
