• The claim originates from a preprint study analyzing VAERS data that reported a proportional reporting ratio (PRR) of 80.1 for “suicide/homicide” adverse events when comparing COVID-19 vaccines with influenza vaccines¹².
• The study does not show that vaccinated people are 80 times more likely to engage in violent behavior. A PRR measures disproportionality in spontaneous reports, not actual incidence, risk, or causation³.
• VAERS is a passive, unverified reporting system that accepts reports from anyone, including the public. It is subject to massive underreporting, duplicate reporting, and stimulated reporting driven by intense media attention and public scrutiny of COVID-19 vaccines⁴³.
• COVID-19 vaccines had expanded mandatory reporting requirements and unprecedented safety monitoring, which artificially inflate reporting rates relative to long-established flu vaccines⁵⁴.
• Health authorities and independent fact-checkers have repeatedly warned that raw VAERS data cannot be used to compare adverse-event rates or risks between vaccines, and VAERS reports alone do not establish a causal link⁵⁶.
• The claim conflates a PRR with an actual risk ratio and mislabels a “suicide/homicide” category as “violent behavior.”
