Actually eSnA2008 - one CAN get chicken pox from someone that has shingles. It is more difficult to pass along the virus when it manifests the 2nd time as Shingles than it's original go around of chicken pox, but it IS possible. Shingles is contagious while the blisters are breaking open. Anyone susceptible (those being anyone not vaccinated or not having chicken pox in the past) can catch the virus during this time. (Chicken pox on the other hand, is spread much the way other viruses are spread - through droplets in the air following sneezing, germy hands touching surfaces, etc.)
My mother had shingles this past year. She was advised not to be near children or adults that were not yet vaccinated or had never had the virus when she was blistered as those could come down with chicken pox as a result of any contact. She's a hospice volunteer and had to cancel all her visits until cleared by the doctor.
