Data source: VAERS (Vaccine Adverse Event Reporting System)

Data through 2026 · Updated quarterly

Built by TheDataProject.ai · © 2026 VaccineWatch

Important: VAERS accepts reports of adverse events following vaccination. For any given report, there is no certainty that the reported event was caused by the vaccine. Reports may contain information that is incomplete, inaccurate, coincidental, or unverifiable. Most reports to VAERS are voluntary, which means they are subject to biases. This data cannot be used to determine if vaccines cause or contribute to adverse events.

⚠️

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.

1999 Reporting Summary

In 1999, 648 adverse event reports were filed for Anthrax (Biothrax) in VAERS. This represents 5.6% of all 11,622 reports for this vaccine.

Compared to the average of 372 reports per year for this vaccine, 1999 was above average (+74%).

💡 What This Means

Year-over-year change: The large change from 1998 likely reflects a ramp-up in vaccination (e.g., new vaccine rollout or expanded eligibility) rather than a change in per-dose risk.

Understanding Yearly Data

•Spikes may reflect awareness: Years with unusual activity (e.g., pandemic) often see increased reporting.
•Dose volume matters: More vaccinations given in a year naturally leads to more reports.
•Reporting lag: Some events are reported months after they occur, so recent years may be incomplete.
