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 8 reports of Complement factor C3 after Vaccine Not Specified vaccination may seem alarming, but context is critical.
The 12.50% mortality rate among these reports is elevated, but this reflects the severity of the condition itself rather than vaccine causation.
