Lemiere. S.

Combined vaccination against myxomatosis and VHD is an innovative approach in rabbit production. Safety of the vaccine was tested according to the European legislation un force. SG33 vaccine showed no spread amongst SPF rabbits in laboratory conditions, no reversion to virulence and no influence upon humoral immunity. The administration of a double dose of the combinated vaccine in females had no influence upon pregnancy and progeny. Challenge tests using myxomatosis and VHD virulent virus strains in laboratory conditions demonstrated the efficacy of the vaccine.
