Chicken pox and 5.5 mths pregnant?

Hi, my daughter is 5.5 mths pregnant, and her friends daughter has just had chicken pox, i know it can be dangerous if my daughter should catch it while pregnant but she has already had it a few years ago, but my question is, if she should go round there is there any chance of maybe her friend getting shingles from her daughters chicken pox and my daughter catching shingles off of her, sounds confusing but i hope you know what im getting at, any help please. Thankyou.
