Reactivation of Herpes Zoster After Recombinant Vaccine (Shingrix): A Case Report.

Herpes zoster (HZ) is a common contagious dermatological condition that results from reactivation of varicella-zoster virus (VZV), which currently could be prevented by vaccination. We describe a rare case of varicella infection reactivation after routine zoster vaccination in an immunocompetent female in her 60s who developed dermatomal pruritic and vesicular rash one week after receiving Shingrix vaccine, along with fever, sweating, headache, and fatigue. The patient was treated as a case of herpes zoster reactivation with a seven days course of acyclovir. She continued to do well on follow-up with no significant complications. Though uncommon, it is important for healthcare providers to recognize this adverse reaction to expedite testing and treatment.
