  • INACTIVATED VIRUS COMPOSITIONS AND METHODS OF PREPARING SUCH COMPOSITIONS
    Publication number: 20180243406
    Abstract: The present invention is directed at a composition comprising a live swine flu virus having an infectious component and a plurality of surface antigens in contact with a formaldehyde donor agent having a molecular weight that is less than about 400 g/mol. Preferably, the formaldehyde donor agent is selected from a non-crosslinking chemical fixative that contains urea.
    Type: Application

  • INACTIVATED VIRUS COMPOSITIONS AND METHODS OF PREPARING SUCH COMPOSITIONS
    Publication number: 20110110975
    Abstract: The present invention is a composition comprising a live virus having an infectious component and a plurality of surface antigens in contact with a formaldehyde donor agent having a molecular weight that is less than about 400 g/mol. The present invention further provides a method for deactivating a live virus having an infectious component and a plurality of surface antigens, comprising the steps of: a) providing a live virus having an infectious component and a plurality of surface antigens; and b) contacting the virus with a formaldehyde donor agent having a molecular weight that is greater than about 50 g/mol and less than about 400 g/mol for a period of time (e.g., at least about 12 hours) sufficient for de-activating the infectious component with the formaldehyde donor agent and for preserving at least a portion of the surface antigens to form a deactivated virus.
