According to vampire folklore how do people protect themselves from vampires?

# You would repulse a vampire the same way you would repulse ordinary people. Just make yourself gross and disgusting. # Dr. Van Helsign was of the opinion that all Vampires are repulsed by garlic. Can't say that this is universally true but I know one or two vampires that didn't like the stuff. # High energy radiation. Good for most vampires although not the elite. So keep a spot-light by your bed. # A sign that reads 'Blood letting tax 19%, we accept all credit cards.'
