Bexsero side effects: where the data is

Reported reactions for Bexsero and the other meningococcal products are compiled on the meningococcal vaccine page: pre-licensure trial reactogenicity, VAERS report counts, and international databases (Canada Vigilance, EudraVigilance, Lareb, VigiAccess). Those counts are spontaneous reports with no denominator — a report does not establish that the vaccine caused the event.

• Pre-licensure clinical trial data
• Post-licensure surveillance (VAERS and international)
• Documented adverse events and causality assessment
• Vaccine Injury Table (VICP) — compensable injuries
