A 15-month-old infant with a history of developmental delay and weight loss with multiple hospital admissions was diagnosed with a pustular lesion identified as vaccine strain varicella at the vaccination site. He was ultimately determined to be HIV infected following a protracted evaluation, which did not initially include HIV since his mother was confirmed HIV seronegative at 3 months gestation.
