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.
678 adverse event reports (+263% vs 2007)
In 2008, 678 adverse event reports were filed for Influenza, Seasonal (Flumist) in VAERS. This represents 10.1% of all 6,739 reports for this vaccine.
Of these reports, 5 mentioned death, 67 involved hospitalization, 171 required ER visits, and 10 reported disability.
Compared to the average of 475 reports per year for this vaccine, 2008 was above average (+43%).
Year-over-year change: The large change from 2007 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.
