The quest to be cured of vampirism is a repeatable quest, I have become a vampire three times on the same character (I mean to full out vampire) and was cured each time. The only way you cannot become a vampire is if you are a warewolf in the companions quest line. You can be cured of being a warewolf but after that you cannot become one again though.
