for the PS3 and I know about the vampire glitch.What can I do to completely avoid vampires? Is there NO CURE whatsoever then?
You don't need to avoid them. Just watch for signs of the disease if you've been around vampires (it shows up in the inventory screen on the page that shows magical effects on your character), and either pray at a chapel or shrine, or take a cure disease potion, before three days have passed. The disease is completely curable in the first three days after you contract it.
