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.
9,612 adverse event reports (+415% vs 2020)
In 2021, 9,612 adverse event reports were filed for Vaccine Not Specified in VAERS. This represents 32.4% of all 29,669 reports for this vaccine.
Of these reports, 215 mentioned death, 702 involved hospitalization, 1,029 required ER visits, and 243 reported disability.
Compared to the average of 1,022 reports per year for this vaccine, 2021 was above average (+841%).
Year-over-year change: The large change from 2020 likely reflects a ramp-up in vaccination (e.g., new vaccine rollout or expanded eligibility) rather than a change in per-dose risk.
