Consider that vampires (fictional creatures) are undead. As such, they cannot die...again. That being established, vampires are said to be able to sense disease in their intended victims. This appears to be the best defense against a vampire attack. In every story I've ever read that addresses this subject, a vampire will not attack a diseased person. No real reason has ever been given that I have noted.
The Twilight saga does not specifically state who was the first vampire ever. Carlisle Cullen, who was born in the 1640s in London England was turned into a vampire over 300 years ago by a Rogue vampire attack in his village, he was bitten my the vampire and turned into one. However the vampire coven known as the Volturi who live in Volterra Italy, have lived for well over 3000 years and act as police…
No because a vampire bat cannot consume enough blood in one shot to kill a human. It is possible if there are at least 30 but it is rare! So no it isn't possible to die from one vampire bat attack! Usally vampire bats suck the blood of larger animals such as cows or horses therefore it is very unlikely that a vampire bat will attack a human!
Nosferatu was the first Dracula movie ever made which came out in 1922. There was a silent film featuring a vampire released in 1913 called the Vampire, which to my knowledge was actually the first vampire movie. Vampire of the coast in (1909) was the first vampire movie ever made and it was a silent movie.
