ImmuCell Corporation develops and markets animal health products, including preventive and treatment solutions for dairy and beef cattle, focusing on disease prevention, detection, and nutritional support.

First Defense Tri-Shield is an oral gel that quickly protects newborn calves from E. coli, coronavirus, and rotavirus, with ImmuCell now prioritizing its market expansion and manufacturing after shifting focus from Re-Tain.
ImmuCell Corporation announced it received an 'Incomplete Letter' from the U.S. Food and Drug Administration (FDA) on December 23, 2025, for its New Animal Drug Application for Re-Tain®, a treatment for subclinical mastitis in dairy cows. This was due to unresolved issues at its contract manufacturer. Consequently, the company announced a strategic pivot to pause further investment in Re-Tain® and focus on expanding its existing and profitable First Defense® product line, including a 50% increase in its sales force.
Following an 'Incomplete Letter' from the FDA regarding its new drug candidate Re-Tain®, ImmuCell's leadership made a decisive strategic pivot to suspend further investment in the product. The company is reallocating capital and resources to expand manufacturing and increase its sales force for its flagship First Defense® product line, signaling a focused effort to accelerate growth in its core market.
