Here are the two ways you can be/become a vampire.
Way 1: You could be born a vampire and don't even know it. Usually, you have your awakening at the age of 11, 12, 13 or 14. If you don't know what a awakening is then it's pretty much like puberty but you get vampire traits. Look it up and find out more, but you will know when you have it.

Way 2: Blood exchange. Not like running in the streets and searching for someone. Ask a friend, family, neighbor or etc. besides vampire are everywhere. Go to vampire website then "How to get turned into a vampire" It's in there but here is the basic description: To get turned into a vampire you need to do a simple exchange of blood with a vampire. Even just a 1/4 teaspoon of blood is more than enough blood to turn you into a vampire. Unlike how this is portrayed in movies, there is no need to drain someone of their blood to the point of death, when turning them into a vampire. Any person that claims they are a real vampire and says that they have to drain you to the point of death to turn you into a vampire, is a poser and should be avoided. As is already commonly believed, when a vampire turns you into a vampire, the vampire must receive the normal persons blood first. This exchange of blood can be done orally. Afterwards the normal person must receive the vampires blood, they can do this orally as well. This is the only way that you can be turned into a vampire. This is possible because being a vampire, and the ability for you to get turned into a vampire is caused by an endogenous retrovirus, go to that page to learn more about it.
