Hannah Song, BA Medical studen Harvard Medical School and Jennifer T. Huang, MD Division of Immunology, Dermatology Program Boston Children's Hospital Boston, MAMedicalResearch.com: What is the background for this study? What are the main findings? Response: Infection with the varicella-zoster virus leads to chickenpox, or primary varicella. The virus then lies dormant and can later reactivate as shingles, or herpes zoster. Varicella-zoster vaccine is made of an attenuated live virus that prevents most people from getting chicken pox, but rarely can reactivate and cause shingles. There were several pediatric patients who presented to our clinics with shingles/herpes zoster that was localized to one extremity. My hunch was that the extremity where the patients had shingles could be the same limb where they had received vaccination. We called the patient’s pediatricians because pediatricians typically document the extremity where the vaccination is given, and confirmed the theory that shingles in vaccinated children may be more likely to occur at the site of vaccination. Importantly, vaccination may modify the classic appearance of shingles, and you might see pink and red papules and pseudovesicles, rather than classic grouped fluid-filled vesicles on a red base.
