The present invention generally relates to a process for designing a recombinant poxvirus for a therapeutic vaccine, i.e. personalized cancer vaccine, said recombinant poxvirus comprising one or more expression cassettes, each for expression of a fusion of a plurality of peptides, i.e. neopeptides, characterized in that it comprises performing by processing means (11) of a server (1) the steps of : (a) selecting a first subset of candidate peptides, wherein said peptides present transmembrane scores below a TMS threshold; b) determining an optimal distribution of the candidate peptides from said first subset to the expression cassette(s) among a plurality of possible distributions, wherein said optimal distribution presents, if there are at least two expression cassettes, the lowest range between the hydropathy scores of at least two expression cassettes; (c) for each expression cassette, determining an optimal slot allocation of the candidate peptides as function of cassette slot occupancy rule so as to select the peptide fusion with the lowest TM score; (d) determining a DNA transfer sequence comprising the nucleotide sequence of the one or more expression cassette(s) for generation of said recombinant poxvirus.

The present application generally relates to the development of live attenuated Pneumoviridae strains suitable for use as a vaccine. Particularly, human metapneumovirus (hMPV) ΔM2-2 strains (rhMPV-E30M31 and rhMPV-E40L42D44) containing point mutations in a PDZ motif of M2-2, which results in a strain that is both attenuated and immunogenic and, notably, maintains the function of F and G proteins. These live attenuated hMPV strains should be suitable for use in a vaccine capable of providing protection against respiratory infection elicited by hMPV. Additionally, human respiratory syncytial virus (hRSV) strains containing point mutations in a PDZ motif of M2-2 should also be suitable for use as a vaccine capable of providing protection against respiratory infection elicited by hRSV. These Pneumoviridae strains should be useful in vaccines for use in humans and animals, e.g., companion animals and livestock, in treating or providing immunoprotection against respiratory infections.

Provided herein are recombinant poxviruses that are stable through successive passaging of the recombinant poxviruses. More particularly, the recombinant poxviruses comprise one or more modified nucleic acids encoding MUC1, CEA, and/or TRICOM antigens, wherein the recombinant poxviruses are stable through successive passaging. Also, provided herein are compositions and method related thereto.

The present invention relates to aqueous compositions conferring improved stability to poxvirus during storage as well as to the use of such compositions and methods for preparing the same. The compositions comprise recombinant human serum albumin (rHSA), gelatin or arginine, or combinations thereof.
