IABS/DCVMN webinar on next generation sequencing

Next Generation Sequencing (NGS) is a new technology that could overcome some of the limitations of the current viral testing methods for demonstrating the absence of adventitious agents in biologics. This report is for the webinar that was organized by the International Alliance for Biological Standardization (IABS) and the Developing Countries Vaccine Manufacturers Network (DCVMN), held on July 20, 2022, as an introduction to the technical and bioinformatics concepts of NGS and to some of the strengths and limitations of using the technology for those working in vaccine production or development. The current state of scientific knowledge and readiness of NGS to replace or supplement the current viral tests was further discussed in the 3rd Conference on NGS for Adventitious Virus Detection in Biologics for Humans and Animals that was held in Rockville, Maryland, USA, on September 27–28, 2022.

The application of NGS to supplement or replace current in vivo and in vitro assays in adventitious virus testing during vaccine production is promising; however, assay performance (sensitivity, specificity, and reproducibility) needs to be demonstrated, which may include laboratory and bioinformatics work. Efforts from regulatory authorities, industry, and researchers are ongoing to facilitate validation and establishment of NGS as a new method for virus detection.
