My impression is that shingles is technically "reactivation" of the pox virus; i.e. you need to have had chicken pox first. I was referring to cases where someone has received the chicken pox vaccine but still gets sick with the chicken pox later in life. Granted, it also looks like the vaccine is made from actual virus?
