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.
15,773 adverse event reports
In 2022, 15,773 adverse event reports were filed for COVID-19 Bivalent (Moderna) in VAERS. This represents 36.7% of all 42,946 reports for this vaccine.
Of these reports, 121 mentioned death, 776 involved hospitalization, 1,538 required ER visits, and 165 reported disability.
Compared to the average of 10,550 reports per year for this vaccine, 2022 was above average (+50%).
High report volume: 15,773 reports in a single year is significant. This typically reflects large-scale vaccination campaigns rather than increased risk per dose. Without knowing total doses administered in 2022, raw report counts cannot indicate safety rates.
This data comes from the Vaccine Adverse Event Reporting System (VAERS), jointly managed by CDC and FDA.
