Herpes Zoster after COVID-19 Vaccination: Report of 8 Cases

Abstract

Many cases of Herpes Zoster after countries began distributing COVID-19 vaccines; however, none have been reported in Japan. In this study, eight cases of Herpes Zoster were detected among the innoculated with Phizer/Moderna COVID-19 vaccine. The mean age of the patient was 66.5 years, the male to female ratio was 1: 3, and 37.5% of the cases occurred between the first and second doses of the COVID-19 vaccine. The average number of days between vaccination and symptom onset was 8.75 days. The total number of Herpes Zoster patients increased from that of the previous year. When diagnosing Herpes Zoster during the COVID-19 epidemic, recording the date of COVID-19 vaccination and describing the symptoms will make it possible to conduct retrospective survey, so we prepared this preliminary report for dermatologists.
