Abstract
Reactivation of varicella-zoster virus (VZV) has been reported after the administration of different vaccine platforms against SARS-CoV-2, also among individuals without known immunosuppressive states. Herein, we describe for the first time a case of herpes zoster after mRNA vaccination against SARS-CoV-2 in a 53-year-old immunocompetent adult without any known comorbidities, who was previously vaccinated with a live attenuated zoster vaccine. The fact that the patient had no history of varicella and had been tested seronegative for VZV prior to immunization with the live attenuated zoster vaccine further contribute to the challenge of this unusual case. This advocates for a high level of vigilance on the part of clinicians regarding this rare complication among receivers of COVID-19 vaccines.
