Disclosed herein are methods and systems for manufacturing viral vectors (e.g., lentiviral vectors) using a static light scattering device in-line with a manufacturing process.

Methods for producing viruses from adherent cells are provided. The methods include releasing virus from adherent host cells grown in a bioreactor, and purifying released virus by ultrafiltration and/or diafiltration. The methods can be used to manufacture viruses, including for clinical use, at reduced cost relative to conventional virus manufacturing methods.

The present invention relates to virus growth media that improve the yield of alpha-herpesviruses (e.g., HSV-2) grown in cell cultures. The growth media of the invention include two additives, a disaccharide and a lipid mixture, that can be added to serum-free or serum-enriched growth media to improve the efficiency of virus production. The invention further provides methods of producing alpha-herpesviruses (e.g., HSV-2) in such growth media.

The present invention relates to a recombinant Koi herpesvirus (KHV), methods for the production of such KHV, cells comprising such KHV and the use of such KHV as vector and in vaccines for the prevention and/or therapeutic treatment of a disease in fish caused by Koi herpesvirus in carp such as Cyprinus carpio carpio or Cyprinus carpio koi.
