Give Your Virus and Viral Vaccine Production a Boost with CRISPR/Cas9-Engineered Host Cells Webinar

March 10, 2022, at 12:00 PM ET


The continual emergence of novel viral pathogens underscores the already urgent need to accelerate vaccine manufacturing processes. Current production workflows using mammalian cell systems rely on the large-scale culture of a handful of continuous cell lines that in turn produce viral particles or antigens. To help speed the antiviral vaccine development process, ATCC used CRISPR/Cas9 gene editing to increase the virus production efficiency of Vero and MDCK, some of the cell lines commonly used for viral vaccine manufacturing. These cells produce clinical viruses such as Dengue virus type 2 strain New Guinea C and Influenza A virus at titers 10-fold higher than the corresponding parental cell line, suggesting that incorporating these cells into your virus production workflow may significantly reduce the costs associated with viral vaccine manufacture.

Key Points

  • Most viral vaccines are manufactured in large-scale tissue culture systems using historical cell lines that are approved for vaccine manufacturing.
  • ATCC used CRISPR/Cas9 gene-editing techniques to increase the viral production efficiency of some of these historical cell lines.
  • These enhanced virus-producing cell lines have the potential to significantly reduce the costs associated with generating viral vaccines and high-titer viral stocks.
