  • Publication number: 20240000920
    Abstract: The present invention provides recombinant vectors encoding a chimeric coronavirus spike protein. The present invention further provides new immunogenic compositions and vaccines comprising these recombinant vectors. Methods of administering these immunogenic compositions and vaccines to animal subjects, including humans, felines, and avians, to protect them against coronaviruses also are included. Methods of making the immunogenic compositions and vaccines alone or in combinations with other protective agents are provided too.

  • Publication number: 20220315953
    Abstract: The present invention pertains to a Madin-Darby bovine kidney (MDBK) cell, wherein the interferon regulatory factors (IRF) IRF3 and/or IRF7 encoding genes are functionally inactivated. The invention also pertains to a cell culture comprising the MDBK cell, use of the MDBK cell culture, a method for the production of a virus using the cell and a vaccine prepared by using the cell.

  • Publication number: 20220220452
    Abstract: The present invention pertains to a novel rotavirus, especially an isolated vims, which is a member of the sub-species of porcine group B rotavirus (porcine RVB), causing diarrheal disease in pigs, to DNA fragments and corresponding proteins of the said virus, to vaccines on the basis of said virus, DNA and/or protein and to antibodies reactive with said virus and/or protein and diagnostic test kits for the detection of said vims.

  • Patent number: 11291715
    Abstract: The present invention relates to the use of a diluent for the in-use stabilisation of cells infected with a cell-associated alphaherpesvirus. Contrary to the long-standing practice of incorporating a considerable amount of peptone into the diluent for such virus-infected cells, it was found that a reduction of the amount of protein in the diluent improved the in-use stability of alphaherpesvirus-infected cells. Whereby the best stability was even obtained using a protein-free diluent. This effect was especially pronounced for recombinant HVT viruses expressing a heterologous insert. Being protein-free is highly advantageous for the production of the diluent, in respect of costs, safety, and consistency of production.
