First Claim
1. A process for preparing a recombinant herpesvirus for a vaccine or therapy, which comprises:
- (a) culturing host cells, selected from the group of host cells consisting of Vero, or MRC5 cells, infected with the virus,(b) separating the medium from the infected cells and(c) using the separated virus containing medium for further purification, immunotherapy or vaccination of an animal.

Abstract
Methods are disclosed for the preparation of herpesvirus, such as herpes simplex virus type 2 for vaccine use. Such viruses can be grown on serum free or serum containing media and can be prepared from the virus containing culture supernatant or virus containing cells. The virus is prepared for subsequent pharmaceutical formulation by methods which may include treatment with solid phase affinity reagents containing sulfate- or sulfonate-comprising binding groups. Such sulfated polysaccharide groups as heparin or dextran sulfate may be used, and eluted with salt solutions. The process can be combined with other culture, harvesting and formulation steps.
