  • Title: Current challenges in viral safety and extraneous agent testing.
    Author: Mackay D, Kriz N.
    Journal: Biologicals; 2010 May; 38(3):335-7. PubMed ID: 20338787.
    Abstract:
    There are three principal elements related to viral safety in the context of immunological veterinary medicinal products: the presence of extraneous agents in either raw material used for production or in the finished product, residual pathogenicity of live viruses used as active ingredients, and incomplete inactivation of inactivated viruses used as active ingredients. Although the approach to controlling these areas of risk has not substantially changed in the recent past, a number of events, combined with advances in science and changes in the regulatory approach, make it timely to review the requirements in this area. This article reviews the major areas of change and progress with respect to the viral safety of immunological veterinary medicinal products and identifies current challenges from the perspectives of both industry and regulators.
