Erratum: In the Photoclinic item titled "Vaccine-Induced Herpes Zoster," by Julie L. Cantatore-Francis, MD, and Yelva Lynfield, MD (Consultant For Pediatricians, June 2005, pages 290 and 291), the dosage of acyclovir was incorrectly printed as 80 mg/d divided into 4 doses. The correct dosage is 80 mg/kg/d divided into 4 doses. We apologize for the error.
