Possibly shingles?: Chicken pox and shingles are of the same zoster virus. If a person has no good immunity to the zoster virus (never caught chicken pox, is immunosuppressed, never got the vaccine, or got the vaccine but did not make enough antibodies) then she can catch chicken pox from the zoster virus. She cannot catch shingles but can later develop shingles by "reactivating" her own zoster virus sometime later.
