[@luclovers] Both. Vampirism is an ancient blood virus, a genetic disease. You can one: insert your blood into a human, causing them to convert. Or two: have vampire to vampire sex, pass it onto your child. Your vampire child will stop growing at the age the mother figure was converted. For instance, my girl was turned at the age of 26. If she were to have vampire on vampire sex, and get preggo, the baby would stop growing at the age of 26.
