Can children get chicken pox from shingles?

Yes: Chicken pox and shingles are due to the same virus (the zoster virus). If a child 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 he can get a case of chicken pox from the virus in the open skin lesions of the shingles patient.

Yes.: Shingles lesions contain active chicken pox virus, so a child can catch chicken pox if they have direct physical contact with the rash. It does not transmit through the air. If a child has had both recommended doses of chicken pox vaccine, generally given at age 1 and 4, they're likely to be immune.
