The disclosure relates to ovarian cancer neoantigens, polynucleotides encoding them, vectors, host cells, recombinant virus particles, vaccines comprising the neoantigens, proteinaceous molecules binding the ovarian cancer neoantigens, and methods of making and using them.

The present invention provides a viral vector or bacterial vector, said vector comprising a nucleic acid sequence encoding a Crimean-Congo Haemorrhagic Fever Virus (CCHFV) glycoprotein or antigenic fragment thereof; wherein said vector is capable of inducing an immune response in a subject. The present invention also provides compositions and uses of the vector in methods of medical treatment.

A nucleic acid molecule can code for an Orf virus vector promoter. A recombinant Orf virus vector can be included in a cell. The nucleic acid molecule, the vector and/or the cell can be included in a composition. The recombinant Orf virus vector can be used for the production of a foreign gene.

The present application relates to novel administration regimens for poxviral vectors comprising nucleic acid constructs encoding antigenic proteins and invariant chains. In particular the use of said poxviral vectors for priming or for boosting an immune response is disclosed.

A method of treating or preventing graft versus host disease (GVHD) in a subject receiving a graft comprising hematopoietic cells is provided. The method comprises contacting the graft ex vivo with an amount of a Myxoma Virus effective to inhibit proliferation of T lymphocytes in the graft and to treat or prevent GVHD in the host subject following infusion of the graft into the subject. After the contacting of the graft with the Myxoma Virus, the method comprises transplanting the virus-treated graft into the subject.

The invention is a method for assessing protein expression by recombinant expression systems. The method uses mass spectrometry to quantify protein expression. The method has particular application in potency testing of vaccine compositions.
