The present invention provides vaccines comprising carbohydrate antigen conjugated to a diphtheria toxin (DT) as a carrier protein, wherein the ratio of the number of carbohydrate antigen molecule to the carrier protein molecule is higher than 5:1. Also disclosed herein is a novel saponin adjuvant and methods to inhibit cancer cells, by administering an effective amount of the vaccine disclose herein.

Isolated peptides comprising one or more antigenic sites of filovirus glycoprotein and methods of their use and production are disclosed. Nucleic acid molecules encoding the peptides are also provided. In several embodiments, the peptides can be used to induce an immune response to filovirus glycoprotein, such as Zaire ebolavirus glycoprotein, in a subject, for example, to treat or prevent infection of the subject with the virus.

Provided herein is a method of treating or preventing a disease or disorder (e.g., MS) in a subject in need thereof, comprising (a) administering to the subject a first dose of a pharmaceutical composition comprising a fumarate agent (e.g., DMF) for a first dosing period; (b) administering a vaccine; and (c) administering to the subject a second dose of the pharmaceutical composition for a second dosing period.

The present disclosure includes a fusion protein, called a Seldeg, including a targeting component that specifically binds to a cell surface receptor or other cell surface molecule at near-neutral pH, and an antigen component fused directly or indirectly to the targeting component. The antigen component is configured to specifically bind a target antigen-specific antibody. The present disclosure also includes a method of depleting a target antigen-specific antibody from a patient by administering to the patient a Seldeg having an antigen component configured to specifically bind the target antigen-specific antibody.

Described herein is a fusion protein comprising a bacteriophage protein fused to a cancer antigen. Vaccines are also described, as well as methods of treatment and/or prevention of cancer and methods of immunizing an individual.

Immunogenic influenza hemagglutinin-derived peptide compositions described herein induce a specific therapeutic antibody response against influenza virus. The immunogenic peptide compositions comprise a segment from the fusion initiation region (FIR) domain of an influenza hemagglutinin protein bound to an immunogenic carrier protein, such as an influenza hemagglutinin (HA) protein (i.e., full length HA), and the like. The immunogenic peptide compositions described herein can be utilized to treat or prevent influenza infection and to prepare influenza-specific therapeutic antibodies that interfere with influenza virus-host cell membrane fusion. The peptide conjugates can be formulated in pharmaceutical compositions useful for broad spectrum treatment or prevention of influenza infections.

Disclosed is a vaccine, preferably for use in the prevention or treatment of an interleukin 23 (IL-23) related disease, comprising a peptide bound to a pharmaceutically acceptable carrier, wherein said peptide is selected from the group QPEGHH-WETQQIPSLS (SEQ ID No. 103; p8322), GHHWETQQIPSLSPSQPWQRL QPEGHHWETQ (SEQ ID No. 98; p8461), TQQIPSLSPSQ (SEQ ID No. 99; p8400), QPEGHHWETQQIPSLSPSQ (SEQ ID No. 100; p9269), QPEGHHWETQQIPSLSPS (SEQ ID No. 101; p9269-C1), and QPEGHHWETQQIPSLSP (SEQ ID No. 102; p9269-C2), especially QPEGHHWETQQIPSLS (SEQ ID No. 103; p8322) and wherein said IL-23 related disease is selected from the group psoriasis, psoriatic arthritis, rheumatoid arthritis, systemic lupus erythematosus, diabetes, preferably type 1 diabetes, atherosclerosis, inflammatory bowel disease (IBD)/M. Crohn, multiple sclerosis, Behcet disease, ankylosing spondylitis, Vogt-Koyanagi-Harada disease, chronic granulomatous disease, hidratenitis suppurtiva, anti-neutrophil cytoplasmic antibodies (ANCA-) associated vasculitides, neurodegenerative diseases, preferably M. Alzheimer or multiple sclerosis, atopic dermatitis, graft-versus-host disease, cancer, preferably Oesophagal carcinoma, colorectal carcinoma, lung adenocarcinoma, small cell carcinoma, and squamous cell carcinoma of the oral cavity, especially psoriasis, neurodegenerative diseases or IBD.

A safe and effective vaccine to prevent, slow, halt or reverse progression of Alzheimer's disease in human patients is disclosed. The vaccine includes A1-42 or an beta amyloid self epitope (e.g. A1-15, or other 7-mer or 15-mer peptide epitopes derived from A1-42) conjugated to an immunogenic carrier (e.g. DT) formulated in a water-in-oil Th2-biased adjuvant/delivery system.
