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.
1,767 adverse event reports (+384% vs 2018)
In 2019, 1,767 adverse event reports were filed for Vaccine Not Specified in VAERS. This represents 6.0% of all 29,669 reports for this vaccine.
Of these reports, 20 mentioned death, 142 involved hospitalization, 174 required ER visits, and 51 reported disability.
Compared to the average of 1,022 reports per year for this vaccine, 2019 was above average (+73%).
Year-over-year change: The large change from 2018 likely reflects a ramp-up in vaccination (e.g., new vaccine rollout or expanded eligibility) rather than a change in per-dose risk.
