If I particularly needed my child to get it at this time for some reason, I guess I might. I don't really trust that strain though. DD got it from a little girl who got it from her father who had shingles. I think that means it was the same CP strain that the father had as a child. OTOH, I never thought about it before, but if some strains are more prone to causing shingles, then one that has definitely caused shingles might not be the greatest bet either.
