Method of inactivating enveloped viruses in a viral preparation of non-enveloped viruses

摘要

Inactivation of a virus coated in a viral preparation containing principally non coated virus is new and comprises introducing into the viral preparation an sufficient quantity of a solvent and leave to adjust to a temperature of -5 - 50 degrees C, at a pH of 5-9 for a sufficient amount of time to significantly reduce the amount of viral preparation coated virus. Independent claims are also included for the following: (1) a process for the preparation of the viral preparation; and (2) the viral preparation.
