Vaccine-Strain Herpes Zoster Ophthalmicus in a 14-month-old Boy Prompting an Immunodeficiency Workup: Case Report and Review of Vaccine-strain Herpes Zoster.

We present a case of herpes zoster ophthalmicus in an otherwise healthy 14-month-old male associated with vaccine-strain varicella-zoster virus 11 weeks after monovalent varicella vaccine administration. Herpes zoster ophthalmicus, especially in the setting of familial immunoglobulin A deficiency, prompted further immunologic workup. A high index of suspicion is necessary for timely diagnosis and treatment of vaccine-strain herpes zoster.
