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 Body temperature in VAERS

•Temporal association only: These reports show Body temperature 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 Body temperature. 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.
