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.

Understanding Erythema multiforme in VAERS

•Temporal association only: These reports show Erythema multiforme 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.
