The present invention relates to recombinant modified vaccinia virus Ankara (MVA) and to methods of using the same. In particular, the invention relates to recombinant MVA comprising a nucleotide sequence encoding for a structural protein of an equine encephalitis virus (EEV) excluding encoding for a capsid protein of the EEV, a composition in particular a pharmaceutical composition, a vaccine or kit comprising the recombinant MVA, uses and methods thereof e.g., suitable for treating and/or preventing a western, Venezuelan, and/or eastern equine encephalitis virus caused disease.

A vaccine delivery method is presented that includes a composition including as one component a slurry matrix that is a liquid at room temperature and a gel at physiological pH, physiological salt concentrations and/or physiological temperatures and as a second component one or more antigens. Also included are methods of inducing an immune response in a subject and vaccinating a subject by administering such compositions.

Provided is a method for producing an artificial recombinant virus of the family Reoviridae, the method comprising the steps of: (1) introducing a FAST protein expression vector and/or a capping enzyme expression vector into host cells; (2) introducing a vector containing expression cassettes for individual RNA genome segments of a virus or introducing a set of single-stranded RNA transcripts from the expression cassettes into host cells; and (3) culturing the host cells.

The method of the present invention allows more efficient production of an artificial recombinant virus of the family Reoviridae as compared with conventional methods and allows artificial recombinant rotavirus production without using a helper virus.

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.
