Herpes zoster reactivation — a.k.a. shingles — following COVID-19 vaccination in six patients with comorbid autoimmune/inflammatory diseases may be a new adverse event associated with the Pfizer/BioNTech mRNA vaccine, suggested a new report.
At two centers in Israel, there have been six cases of herpes zoster developing shortly after administration of the Pfizer vaccine in patients with disorders such as rheumatoid arthritis since December 2020, according to Victoria Furer, MD, of Tel Aviv University, and colleagues.
