In the older lore, vampires where usually people who had died unnaturally (such as falling off a wagon, murdered, etc.) and couldn't face true death yet, had been killed by a vampire, or an animal had walked over their grave. Also, witches, were-wolves, and cruel or evil people became vampires after death. It was believed that children born with cauls, teeth, or feet first were going to become vampires, as well as any child who died before baptism. In modern lore, a vampire can bite his victim one to three times, or perform a blood exchange (suck his victim dry and replace the victim's blood with his own) to make the victim a vampire.
