Answer: Along with the original answer, it was only those victims where he took enough blood over a long period of time, until they are absolutely drained, did they transform into a vampire. Those victims who were only bit in order to satisfy a bloodlust did not transform, even if they ended dying later from things like blood loss or infection.
Answer: That's for the modern day vampire. The original myths state that a person who dies by the bite of a vampire will rise as one, watch the classic Hammer Films from the 1950's.
