Is there a way to defense from vampire attack?

I finally bought the GP and am loving the vampires didn't think I would but do. I am playing a legacy and have turned all but two of the family and will leave them alone. My 4th gen is a writer she is behaving rather evil all though she isn't but she is fun. She likes to break into sleeping sims homes and have a little drink. Her teen daughter is not that way she has been turned. Maybe we should adopt. We have butler to feast off of and the maid.
