Safety of COVID-19 vaccination in patients with previous cerebral venous sinus thrombosis.

ABSTRACT:

Introduction

Cerebral venous sinus thrombosis (CVST) after coronavirus (COVID-19) vaccination has been reported. There are no data about thrombosis risk in prior CVST patients. The objective of the study was to describe short-term serious adverse events to COVID-19 vaccines in patients with history of CVST.

Material and methods

We present an observational prospective study of patients with known CVST who received COVID-19 vaccination. Serious event rates within 30 days after second dose vaccination (except one dose for Janssen) were evaluated, including recurrences, hospital admission and death.

Results

The 62 vaccinated patients received: BNT162b2 (Pfizer-BioNTech) in 43 patients (69.4%), mRNA-1273 (Moderna) in 7 patients (11.3%), AZD1222 (ChAdOx1) in 7 patients (11.3%) and Ad26.COV2.S (Janssen) in 5 patients (8.1%). There were no thrombotic recurrences within 30 days of vaccination (95% confidence interval, 0.0-5.8). There was one death (1.6%), not attributable to the vaccine.

Conclusions

COVID-19 vaccines are safe for previous CVST patients.
