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.
#306 most reported symptom for this vaccine
Haemoglobin decreased has been reported 72 times in association with DTaP vaccination in VAERS. This represents 0.1% of all 66,714 reports for this vaccine.
Among these reports, 4 mentioned death (5.56%) and 54 involved hospitalization (75.0%).
Haemoglobin decreased is the #306 most frequently reported symptom for DTaP out of 1943 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 72 reports of Haemoglobin decreased after DTaP vaccination may seem alarming, but context is critical.
The 5.56% 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.
