Transverse Myelitis Related to SARS-CoV-2 Vaccines in Patients: an Observational and Retrospective Study Using the WHO's Pharmacovigilance Database

Few patients receiving SARS-CoV-2 vaccines may experience rare but serious adverse events such as transverse myelitis (TM). Today, data about TM are scarce.

The objective was to investigate reports of TM adverse events related to SARS-CoV-2 vaccines labelled by FDA and EMA, including ChAdOx1nCov-19 (Oxford-AstraZeneca), BNT162b2 (Pfizer/BioNTech), mRNA-1273 (Moderna) and Ad26.COV2.S (Janssen/Johnson & Johnson) and using the World Health Organization's (WHO) pharmacovigilance database: VigiBase.
