Maurice R. Hilleman Center Vaccine Manufacturing Expansion

Merck's 225,000 sq ft vaccine active-ingredient manufacturing facility at the Maurice R. Hilleman Center for Vaccine Manufacturing in Durham, North Carolina. Announced July 25, 2019 and completed in March 2025, recorded at month precision. Merck said the completed facility generates nearly 400 full-time roles; AFT records 400 as the transparent rounded figure. The original announcement carried a $650 million investment target for the same 225,000 sq ft building; Merck's completion release identifies the finished facility at $1 billion, so AFT records the revised total cost once and explicitly excludes the superseded $650 million figure rather than treating it as additional capital. The approximately 4,000 construction jobs and Merck's national investment rollups are excluded.

Why this project qualifies

With $1 billion in facility-specific investment and 400 permanent operating jobs announced, this project clears both of AFT's qualifying thresholds ($100 million in facility-specific investment OR 100 permanent operating jobs). This project also meets AFT's primary-source verification and physical U.S. manufacturing-footprint requirements.

Why it matters

The pharmaceuticals context.

Pharmaceutical manufacturers are committing billions to new U.S. production capacity for active ingredients, injectable medicines, biologics and other high-demand treatments. North Carolina and Indiana remain major centers of investment, while new facilities are being planned across the South. The current project pipeline includes both large greenfield campuses and major expansions of established production sites.
