Herpes zoster is an uncommon disease in children, especially in healthy children. The clinical studies and observations of herpes zoster have been focused to children with hemato-oncologic diseases or immuno-compromised conditions. Recently the association of herpes zoster after varicella vaccine (Oka strain) immunization has been concerned and some cases of normal children after varicella vaccination have been reported. We experienced two eases of herpes zoster in healthy children after varicella vaccination. (Korean J Dermatol 2001; 39(2): 250~252)
