What's the best way to protect youself from a vampire?

According to folklore, there are a number of ways to protect yourself from vampires, including the ever-popular wearing of garlic or a religious symbol. You can slow a vampire down by giving him something to do, like pick up poppy seeds or unravel a net. (They're quite compulsive.) Cross water and he can't follow. If you can find the body, give it a bottle of whiskey or food so it doesn't have to travel. If that doesn't work, either shoot the corpse (may require a silver bullet) or drive a stake through the heart. And remember, the vampire won't enter your dwelling unless invited.
