The invention relates to recombinant viral vectors for the insertion and expression of foreign genes for use in safe immunizations to protect against a variety of pathogens. The invention also relates to multivalent compositions or vaccine comprising one or more recombinant viral vectors for protection against a variety of pathogens. The present invention relates to methods of making an using said recombinant viral vectors.

The present invention relates to recombinant herpes viruses comprising recombinant nucleotide sequences encoding at least two different antigens. The invention is particularly suited for producing vaccines to immunize avian species against avian pathogen(s).

The present invention relates to the field of (vector) vaccines, and especially to novel EHV's having an inactivation of UL18 and/or UL8. The present invention further concerns related expression cassettes and vectors, which are suitable to express genes of interest, especially antigen encoding sequences. The viral vectors of the present invention are useful for producing an immunogenic composition or vaccine.

The invention relates to a recombinant Gallid herpesvirus 3 vector encoding heterologous avian pathogen antigens comprising one or more heterologous polynucleotide(s) inserted into the intergenic loci UL3/UL4 and/or UL21/UL22. The invention further relates to vaccines comprising said recombinant Gallid herpesvirus 3 vector and optionally a further Marek's disease virus vector and to a use of the vaccine for protecting an avian species against one or more avian pathogens. Further methods for treating an avian species for protection against one or more diseases caused by avian pathogens and a method for producing the recombinant Gallid herpesvirus 3 vector encoding heterologous avian pathogen antigens is provided.

Disclosed herein are methods and systems for manufacturing viral vectors (e.g., lentiviral vectors) using a static light scattering device in-line with a manufacturing process.

The present invention provides compositions and methods for inducing immune responses in subjects using HV-based vectors that can be grown in single celled organisms and administered in their nucleic acid form.

Novel adeno-associated virus (AAV) vectors in nucleotide and amino acid forms and uses thereof are provided. The isolates show specific tropism for certain target tissues, such as blood stem cells, liver, heart and joint tissue, and may be used to transduce stem cells for introduction of genes of interest into the target tissues. Certain of the vectors are able to cross tightly controlled biological junctions, such as the blood-brain barrier, which open up additional novel uses and target organs for the vectors, providing for additional methods of gene therapy and drug delivery.

Provided herein are methods for generating reversion free attenuated and/or replication incompetent vaccine vectors and their use in vaccine compositions and vaccination. In particular, the use of a codon shuffled helper gene is used to produce compositions comprising replication incompetent virus.

The present disclosure provides recombinant nucleic acids comprising one or more polynucleotides encoding a cystic fibrosis transmembrane conductance regulator (CFTR) polypeptide (e.g., a human CFTR polypeptide); viruses comprising the recombinant nucleic acids; compositions and formulations comprising the recombinant nucleic acids and/or viruses; methods of their use (e.g., for the treatment of a chronic lung disease, such as cystic fibrosis); and articles of manufacture or kits thereof.

Provided herein is a fusion protein comprising, or alternatively consisting essentially of, or yet further consisting of an optional signal peptide, a serum albumin, an optional linker, a Phosphatase and Tensin Homolog (PTEN), and an optional purification or detectable marker in any order. Relating polynucleotides, vectors, host cells, pharmaceutical compositions and kits are also disclosed. Further provided are methods for delivering a fusion protein to a subject, treating a cancer or tumor, and/or producing the fusion protein.
