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.
#218 most reported symptom for this vaccine
Subarachnoid haemorrhage has been reported 20 times in association with Polio (Oral) vaccination in VAERS. This represents 0.1% of all 27,089 reports for this vaccine.
Among these reports, 20 mentioned death (100.00%) and 18 involved hospitalization (90.0%).
Subarachnoid haemorrhage is the #218 most frequently reported symptom for Polio (Oral) out of 558 total symptoms.
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 20 reports of Subarachnoid haemorrhage after Polio (Oral) vaccination may seem alarming, but context is critical.
The 100.00% mortality rate among these reports is elevated, but this reflects the severity of the condition itself rather than vaccine causation.
This data comes from the Vaccine Adverse Event Reporting System (VAERS), jointly managed by CDC and FDA.
