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.
Lederle Laboratories has 12,319 adverse event reports in VAERS, representing 0.5% of all manufacturer-attributed reports.
Of these reports, 437 mentioned death and 1,418 involved hospitalization.
Lederle Laboratories produces 6 vaccines tracked in VAERS. Their relatively low report count reflects a smaller market presence or specialized vaccine portfolio.
This data comes from the Vaccine Adverse Event Reporting System (VAERS), jointly managed by CDC and FDA.
