External Supply (ES) is responsible for managing a network of third-party contract manufacturing organizations (CMOs) that make and supply Pfizer medicines for our patients. We are a critical part of the supply chain and support our growth products, including those that are lifesaving or medically significant to our patients

Accounting for approximately 25% of Pfizer’s global volume, we manage over 300 CMOs that supply over 400 products to patients in over 100 countries.

To ensure timeliness, quality, compliance and safety of Pfizer medicines, we use the Virtual Site Operating Team (VSOT) model to manage our network of CMOs.

Each VSOT is consists of cross functional teams including subject matter experts and maintains the same standards and processes as Pfizer’s own internal manufacturing operations, with an eye on quality supply. This model enables proactive management of product supply and cost, aligned with our purpose of bringing breakthroughs that change patients’ lives.
