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.
995 adverse event reports (+462% vs 1993)
In 1994, 995 adverse event reports were filed for DTP + Hib in VAERS. This represents 14.4% of all 6,892 reports for this vaccine.
Of these reports, 62 mentioned death, 170 involved hospitalization, 406 required ER visits, and 20 reported disability.
Compared to the average of 692 reports per year for this vaccine, 1994 was above average (+44%).
Year-over-year change: The large change from 1993 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.
