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.
#296 most reported symptom for this vaccine
Hepatitis B core antibody negative has been reported 12 times in association with Hepatitis A + B (Twinrix) vaccination in VAERS. This represents 0.2% of all 5,237 reports for this vaccine.
Among these reports, 3 mentioned death (25.00%) and 0 involved hospitalization (0.0%).
Hepatitis B core antibody negative is the #296 most frequently reported symptom for Hepatitis A + B (Twinrix) out of 871 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 12 reports of Hepatitis B core antibody negative after Hepatitis A + B (Twinrix) vaccination may seem alarming, but context is critical.
The 25.00% 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.
