Seven immunocompetent patients aged > 50 years old presented with herpes
zoster (HZ) infection in a median of 9 days (range 7-20) after
vaccination against SARS-CoV-2. The occurrence of HZ within the time
window 1-21 days after vaccination defined for increased risk and the
reported T cell-mediated immunity involvement suggest that COVID-19
vaccination is a probable cause of HZ. These cases support the
importance of continuing assessment of vaccine safety during the ongoing
massive vaccination for the COVID-19 pandemic and encourage reporting
and communication of any vaccination-associated adverse event
