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 Infection Reports

Of these reports, 403 were associated with death (2.58%) and 2,425 involved hospitalization.
The overall serious outcome rate (death or hospitalization) for reports mentioning Infection is 18.1%.
Understanding Infection in VAERS
•Temporal association only: These reports show Infection 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 Infection. 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.
