Important: VAERS reports alone cannot determine if a vaccine caused an adverse event. Reports may contain incomplete, inaccurate, or unverified information. Correlation does not equal causation.
1,439 adverse event reports (+336% vs 2015)
In 2016, 1,439 adverse event reports were filed for Meningococcal B (Trumenba) in VAERS. This represents 12.7% of all 11,323 reports for this vaccine.
Of these reports, 0 mentioned death, 51 involved hospitalization, 308 required ER visits, and 11 reported disability.
Compared to the average of 979 reports per year for this vaccine, 2016 was above average (+47%).
Year-over-year change: The large change from 2015 likely reflects a ramp-up in vaccination (e.g., new vaccine rollout or expanded eligibility) rather than a change in per-dose risk.
