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 Dyspepsia Reports
Dyspepsia has been reported 3,559 times in VAERS from 1990 to 2026.
Of these reports, 42 were associated with death (1.18%) and 334 involved hospitalization.
The overall serious outcome rate (death or hospitalization) for reports mentioning Dyspepsia is 10.6%.
Understanding Dyspepsia in VAERS
•Temporal association only: These reports show Dyspepsia occurred after vaccination, not necessarily because of vaccination.
•Background rates matter: Many symptoms occur naturally at baseline rates in the population, unrelated to vaccination.
•Reporting variability: Medical terminology may be used differently by various healthcare providers and over time.
•Investigation needed: High-frequency reports may trigger further epidemiological studies to determine causation.
What This Data Shows
Most Associated Vaccines: The vaccines most frequently mentioned in reports with Dyspepsia. This may reflect usage patterns, not causation.
Severity Patterns: The percentage of reports that involve serious outcomes can help prioritize safety investigations.
Reporting Trends: Changes in reporting frequency over time may reflect increased awareness, media attention, or actual safety signals.
