why doesn't a werewolf bite not affect an original??

have you read the book?? cause i already know all of that..but i want to know the explanation as to why werewolf bites wouldln't affect Elijah. cause he's a vampire..and does that mean he's the original werewolf as well or are there original werewolves??

Are you asking about the t.v. show or the books because I am going on what I saw on the T.V. show. Only Klaus is a hybred, not all vampires are part werewolf according to the show. it has been a while since I have read the books.With what I have seen on the show the wolf bite wouldn't affect elijah ( I could be wrong) because of the fact that it only affects recent vampires and not 1000 year old vampires. Hopefully it will be explained in season 3.
