Payments from drug & device makers

What this record shows

The money is spread across several categories — speaking fees (47.7%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. Sanofi Pasteur Inc. accounts for 84.8% of it on its own, with 6 other manufacturers making up the rest. Reporting peaked in 2024 at $48,156 and has fallen 87.5% since, to $6,018 in 2025. Among pediatric infectious diseases clinicians in IL with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
