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.
298 adverse event reports (+405% vs 2013)
In 2014, 298 adverse event reports were filed for Influenza, Seasonal (Flucelvax) in VAERS. This represents 17.6% of all 1,689 reports for this vaccine.
Of these reports, 1 mentioned death, 10 involved hospitalization, 73 required ER visits, and 6 reported disability.
Compared to the average of 170 reports per year for this vaccine, 2014 was above average (+75%).
Year-over-year change: The large change from 2013 likely reflects a ramp-up in vaccination (e.g., new vaccine rollout or expanded eligibility) rather than a change in per-dose risk.
This data comes from the Vaccine Adverse Event Reporting System (VAERS), jointly managed by CDC and FDA.
