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.

Dysgeusia appears in 7,337 VAERS reports across all vaccines. Of these, 8 reports also mentioned death and 190 involved hospitalization. The severity rate (deaths + hospitalizations as a percentage of reports) is 2.7%. The top vaccines associated with this symptom are COVID-19, Flu (Trivalent), Shingles (Zostavax). Remember: VAERS reports show temporal association, not causation.

About Dysgeusia Reports

Dysgeusia has been reported 7,337 times in VAERS from 1990 to 2026.

Of these reports, 8 were associated with death (0.11%) and 190 involved hospitalization.

The overall serious outcome rate (death or hospitalization) for reports mentioning Dysgeusia is 2.7%.

Understanding Dysgeusia in VAERS

•Temporal association only: These reports show Dysgeusia 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 Dysgeusia. 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.
