History Of Having Bell's Palsy. Suggested Getting Shingles Shot. Chances Of Contracting Facial Paralysis?

Hello,my name is Steven Allen Bellmer and my mothers name is Stephanie. Her doctor wants her to get a shingles shot. She believes that this is a bad idea because she had bell's palsy about 50 years ago. Her belief is that there is a chance of her contracting a facial peralysis (vanicella-zoster) I myself would not know because not only do I not have any paients I do not even have a waiting room.
