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.
1,148 adverse event reports (+382% vs 2002)
In 2003, 1,148 adverse event reports were filed for Anthrax (Biothrax) in VAERS. This represents 9.9% of all 11,622 reports for this vaccine.
Of these reports, 15 mentioned death, 92 involved hospitalization, 514 required ER visits, and 15 reported disability.
Compared to the average of 372 reports per year for this vaccine, 2003 was above average (+209%).
Year-over-year change: The large change from 2002 likely reflects a ramp-up in vaccination (e.g., new vaccine rollout or expanded eligibility) rather than a change in per-dose risk.
