The present invention provides recombinant viral vectors containing and expressing antigens of avian pathogens, compositions comprising said recombinant viral vectors, and polyvalent vaccines comprising them. The present invention also provides methods for vaccination against various avian pathogens and a method for producing the recombinant viral vectors.

The invention relates to the field of health care, and more particularly to the prevention of infections that cause pneumonia and other illnesses using an immunogenic protein containing fragments of the proteins FliC, PspA, OmpA and PE, connected by rigid linkers, wherein: - the FliC protein fragment contains SEQ ID NOs: 2 and 3 connected to one another by a flexible linker; - the PspA protein fragment contains SEQ ID NO: 4; the OmpA protein fragment contains SEQ ID NOs: 5-8 connected to one another by flexible linkers; - the PE fragment contains SEQ ID NO: 9. Also proposed are a host cell and a method for producing the protein. The immunogenic protein is suitable for use as a broad-spectrum polyvalent vaccine and exhibits a marked protective effect against Streptococcus pneumoniae, Haemophilus influenzae and Klebsiella pneumoniae, as well as providing for production efficiency and safety.

We provide a novel oral live canine parainfluenza virus vaccine and related polyvalent vaccines. [Solution] A method for providing effective protection to dogs from upper respiratory tract diseases and infectious tracheobronchitis, comprising orally administering a vaccine containing a modified live canine parainfluenza (CPI) virus to the dogs. Methods are also provided for using the vaccine alone or in combination with one or more protective immunogens in a polyvalent vaccine.

The present invention falls within the fields of molecular biology, medical sciences and immunology, and relates especially to preparations for medical purposes. In particular, the present invention relates to immunogenic compositions and / or formulations and / or polyvalent veterinary vaccines with a broad spectrum of protection against serovars of Glaesserella parasuis (G. parasuis), based on inactivated antigens, to a dosage form comprising said vaccine formulation, to the process for producing inactivated G. parasuis antigens, as well as to the process for producing said vaccine formulation. Additionally, the present invention relates to a combination of clinical strains, to the use of said combination of clinical strains in the manufacture of a polyvalent vaccine formulation for the prevention of infections caused by clinical strains of G. parasuis, regardless of their capsular type, which cause Glässers disease (GD), and to a kit comprising a combination of clinical strains and a preservative solution.
