Disclosed herein are methods and exemplary compositions associated with virus purification, antigen purification, and conjugation of virus and proteins (e.g., antigen) to form vaccines for delivery of immunological and other therapeutic agents, exemplary aspects of which may include harvesting viral and antigenic substances from source organisms; a purification platform comprising chemical separation and size-difference separation for the removal of contaminants, debris and impurities from the viral and protein (e.g. antigenic, including influenza hemagglutinin antigens) substances, as well as their concentration and collection; and a conjugation platform providing activation of the virus at a pH that increases binding rate and binding propensity between the virus and the protein, wherein embodiments related to the conjugation platform include controlling the ratio of virus to protein.

In a first aspect, the present invention relates to an isolated nucleic acid molecule, in particular, an RNA molecule containing particular substitutions. In a further aspect, the present invention relates to a composition comprising the same as well as virus-like particle, viral vector or virus particle containing the nucleic acid molecule according to the present invention. The virus-like particle, the viral vector or the virus particle is suitable for use as a medicament in particular for treating viral infection. Further, a pharmaceutical composition is provided in particular suitable for use as a pharmaceutical prophylactic vaccine containing the virus-like particle, viral vector or the virus particle or the nucleic acid molecule according to the present invention. Finally, a vaccine for vaccination against viral infection, in particular, influenza viral infection is provided as well as a composition or kit comprising the virus-like particle, viral vector or the virus particle according to the present invention or the nucleic acid molecule according to the present invention in a combination with a wild type viral vector or wild type virus particle said composition or kit is suitable for use in treating or protecting against viral infection.

The disclosure generally provides recombinant proteins comprising Tobamovirus capsid proteins and an immunogenic epitope of an antigen of interest. The recombinant protein can be used to assemble an array comprising a plurality of associated recombinant proteins that can enhance the immunogenicity of the epitope and induce and/or enhance an immune response to the antigen. The disclosure also provides compositions, such as vaccines, that include the recombinant protein as well as methods for inducing and/or enhancing an immune response in a mammal.

A method of treating cancer in a subject in need thereof includes administering in situ to the cancer a therapeutically effective amount of a virus or virus-like particle.
