  • INACTIVATED PISCINE ORTHOREOVIRUS VACCINE
    Publication number: 20230105140
    Abstract: The invention derives from the discovery that the immunogenicity of piscine orthoreovirus (PRV) can be significantly increased by inactivating the virus in a way different from the prior art: by incubation with an aziridine the vaccine potency against challenge infection by cohabitation is much improved over prior art approaches. This allowed the development of an effective inactivated vaccine against infection and disease caused by PRV.
