GSK has a comprehensive viral safety program for the production of biopharmaceutical which uses a three-fold complementary approach:

  1. Control of Raw Materials

  2. In Process Testing

  3. Demonstration of capability of processing steps to clear virus

These and other considerations are tightly managed through a comprehensive risk management program that has resulted in confidence that the materials that are supplied to patients are free from virus contamination.
