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.

About Cholera

Cholera has 246 reports in VAERS spanning from 1990 to 2026.

Reporting Rate

This vaccine averages 7 reports per year over 33 years of reporting (1990–2025).

Understanding These Numbers

•Reports don't prove causation. They represent temporal associations where someone experienced an event after vaccination.
•Background rates matter. Many conditions occur naturally and may coincidentally happen after vaccination.
•Reporting varies by vaccine. Newer vaccines or those in the news may have higher reporting rates due to increased awareness.
