Understanding Ultrasound scan normal in VAERS
•Temporal association only: These reports show Ultrasound scan normal occurred after vaccination, not necessarily because of 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.
