One recurring aspect of fictional vampires is that they are all "immortal", except that some can lose their immortality (be killed) by various methods. Some are required to feed regularly to live and move about. Otherwise they die or become dormant. --- It depends on the type of vampire and how often they feed. And how they feed. Some are immortal in body, which is rare. Some are immortal souls which are reincarnated. Some have human bodies, but live longer than would be expected (these are usually the ones that unsuccessfully changed into vampires). ---
