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.
Seqirus has 22,370 adverse event reports in VAERS, representing 0.8% of all manufacturer-attributed reports.
Of these reports, 130 mentioned death and 859 involved hospitalization.
Seqirus produces 4 vaccines tracked in VAERS. Their relatively low report count reflects a smaller market presence or specialized vaccine portfolio.
