A METHOD FOR PREPARING A CELL-FREE HERPESVIRUS SUSPENSION OR A FREEZE-DRIED PRODUCT, AND A METHOD FOR PREPARING A VACCINE FROM A SUSPENSION OR PRODUCT OBTAINED.

摘要

New stabilizing compositions for cell-free viruses comprising a buffered solution of polyvinylpyrrolidone, sucrose, glutamate and a chelating agent. The compositions stabilize the viruses during their extraction from the cells to which they are associated and during the lyophilization and/or storage of the cell-free viruses. The compositions are useful for the preparation of cell-free virus vaccines.
