Title. Ive been a vampire once, got it cured. Is that it for my character and vampirism?

Yes, that's it in the vanilla game. After you've cured it once, even if you contract Porphyric Hemophilia again, it'll act like a very minor disease that drains your fatigue by 5 points until you cure it. You won't turn into a vampire anymore.

The only way to re-become a vampire is through mods or the console.

I see, thank for reply
