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.

Disclaimer: VAERS reports describe events that occurred after vaccination but do not establish that the vaccine caused the event. Many reported symptoms may be coincidental or related to underlying conditions.
Seeing 29 reports of Encephalopathy after Tdap (Boostrix) vaccination may seem alarming, but context is critical.
The 17.24% mortality rate among these reports is elevated, but this reflects the severity of the condition itself rather than vaccine causation.
