Can my 7 year old have Shingles?

She has never had chickenpox but got vacsonated for them when she was 5. She has a rash on her sides and up the sides of her back that she says hurts. There are no other rashes on her body. The nurse on call said her and the doctor think that shingles is the only thing they think it could be, and want me to bring her in tomarow. I just want to know if it is even possible for her to have shingles when the only exposure to the virus was a vaccine?
