Killing Vampire with a cross.

Wear a cross. The Christian cross is a symbol aimed at warding off vampires. In novels, it's commonly wielded by innocents and beauties. In many renditions, there must be true faith accompanying the holding of the cross. Play or write it as befits your own beliefs! When role-playing or acting, the person acting as the vampire will need to act aghast and run off. It is also said that vampires hate any religious artifacts.
