Provided are adenoviral vectors for generating an immune response to antigen. The vectors comprise a transcription unit encoding a secretable polypeptide, the polypeptide comprising a secretory signal sequence upstream of a tumor antigen upstream of CD40 ligand, which is missing all or substantially all of the transmembrane domain rendering CD40L secretable. Also provided are methods of generating an immune response against cells expressing a tumor antigen by administering an effective amount of the invention vector. Further provided are methods of generating an immune response against cancer expressing a tumor antigen in an individual by administering an effective amount of the invention vector. Still further provided are methods of generating immunity to infection by human papilloma virus (HPV) by administering an effective amount of the invention vector which encodes the E6 or E7 protein of HPV. The immunity generated is long term.

The invention concerns a method of generating an immune response in a subject, comprising administering to the subject an antigenic molecule, a photosensitizing agent, a checkpoint inhibitor, and irradiating said subject with light of a wavelength effective to activate the photosensitizing agent to generate an immune response. Preferably the method is a method of vaccination. The invention also provides related methods, compositions, cells, uses, products and kits.

The invention provides lipid A mimics in which one or both of the sugar residues of a natural lipid A disaccharide backbone has been replaced with an aromatic group. These lipid A mimics may further differ from a natural lipid A molecule with respect to other structural characteristics, such as, a different number of phosphate groups present, changes in the number, structure and location of lipid chains and/or changes in the spacing and linkage of the sugar residues (or their aromatic replacements). The lipid A mimics may be lipid A agonists and as such may be useful as immunostimulatory agents in inducing or patenting an antibody and/or cell-mediated immune response, or may be lipid A antagonists and as such may be useful in treating or preventing a lipopolysaccharide (LPS)/lipid A-mediated disease or disorder. Also provided are methods for preparing the lipid A mimics.

The present invention relates to prophylactic and/or therapeutic vaccines that contain Newcastle disease Virus (NDV) virus-like particles (VLPs) comprising one or more Epstein-Barr Virus (EBV) antigens. In one embodiment, the invention provides a recombinant virus-like particle (VLP) comprising, in operable combination, a) Newcastle disease virus (NDV) matrix (M) protein, and b) one or more Epstein-Barr Virus (BBV) antigens. The invention's prophylactic and/or therapeutic vaccines are useful for preventing and/or treating infection with EBV and/or disease associated Epstein-Barr Virus, such as cancer.

The present disclosure provides a Farmington virus formulated to induce an immune response in a mammal against a tumour associated antigen. The Farmington virus may express an antigenic protein that includes an epitope from the tumour associated antigen. The Farmington virus may be formulated in a composition where the virus is separate from an antigenic protein that includes an epitope from the tumour associated antigen. The present disclosure also provides a prime:boost therapy for use in inducing an immune response in a mammal. The boost includes a Farmington virus, or a composition that includes a Farmington virus.

A method for treating or reducing the incidence of recurrence of cancer, benign tumors, or HPV-associated lesions, including skin cancer, and particularly squamous cell carcinoma (SCC and basal-cell carcinoma, by administering one or more doses of HPV recombinant vaccine to a patient.

The disclosure relates to vaccination compositions, for example, against human papillomavirus, Zika virus, and flu virus. The disclosure also relates to vectors for producing the virus-like particles and immune complex platforms of the vaccination compositions.

The present application relates to a modified human papillomavirus (HPV) type 52 L1 protein and a use thereof. Specifically, the present application relates to a HPV type 52 L1 protein, a nucleotide encoded thereby, a carrier comprising the nucleotide, a cell comprising the carrier, a pentamer or virus-like particle consisting of the HPV-52 L1 protein, a vaccine comprising the pentamer or virus-like particle and a vaccine adjuvant, and a use thereof in the prevention of HPV infections and HPV infection-related diseases.

The disclosure relates to vaccination compositions, for example, against human papillomavirus, Zika virus, and flu virus. The disclosure also relates to vectors for producing the virus-like particles and immune complex platforms of the vaccination compositions.
