However, people who haven’t previously had chickenpox can contract it from coming into contact with someone who has shingles, since the fluid from the
blisters can carry the virus to others. Even though shingles isn’t as
contagious as chickenpox, it still poses a mild threat to those who have never had it or the chicken pox vaccine. Although it is not possible to spread shingles to others, the chickenpox virus can be spread to anyone who has never had it.
