The present application discloses an immunogenic composition comprising N. meningitidis capsular polysaccharides from at least one of serogroups A, C, W135 and Y conjugated to a carrier protein to produce a N. meningitidis capsular polysaccharide conjugate, wherein the average size of each N. meningitidis polysaccharide is above 50 kDa.

Pre-conditioning a vaccine site with a potent recall antigen such as tetanus/diphtheria (Td) toxoid can significantly improve the lymph node homing and efficacy of tumor antigen-specific DC vaccines. Patients given Td had enhanced DC migration bilaterally and significantly improved survival. In mice, Td pre-conditioning also enhanced bilateral DC migration and suppressed tumor growth in a manner dependent on the chemokines CCL3 and CCL21 and Td-activated CD4.sup.+ T cells. Interference with any component of this axis markedly reduced Td-mediated DC migration and antitumor responses. Our clinical studies and corroborating investigations in mice suggest that pre-conditioning with a potent recall antigen represents a viable strategy to increase DC homing to lymph nodes and improve antitumor immunotherapy.

Provided herein are compounds, compositions, formulations, kits, uses, and methods for immunization against Neisseria meningitidis serogroups A, C, Y, and W-135 and human papilloma virus.

A method for treating a tumor or generating an immune response against a tumor in a subject in need including a vaccination step comprising administration of a first composition, and a tumor-marking step comprising administration of a second composition, is provided. The first and second composition each comprises an antigenic polypeptide (e.g., a non-tumor antigen) or a nucleic acid encoding an antigenic polypeptide. Also provided are antigenic polypeptides and compositions for use in methods described herein.

The present disclosure provides methods and compositions for reducing the incidence, severity, and/or duration of at least one sign of respiratory infection. The methods include the steps of administering a composition comprising gastrointestinal microbiota and an immunogenic composition to an animal in need thereof.

The present invention relates to vesicles derived from bacteria of the genus Propionibacterium and a use thereof. It was experimentally confirmed that the production of vesicles derived from bacteria of the genus Propionibacterium was increased in the body by a high-fat diet rather than a high-carbohydrate diet; the vesicles were significantly reduced in the blood of patients with cancers, such as breast cancer and liver cancer, inflammation diseases, such as asthma and atopic dermatitis, and metabolic diseases, such as diabetes and liver cirrhosis, compared with normal persons; and the vesicles inhibited the secretion of inflammatory mediators by pathogenic vesicles, inhibited the apoptosis of keratinocytes, and increased the expression of an androgen receptor in the body. The vesicles derived from bacteria of the genus Propionibacterium according to the present invention are expected to be advantageously used in a method for diagnosis or prediction of cancers, inflammatory diseases, endocrine diseases, or metabolic diseases, a pharmaceutical composition, a food, a cosmetic product, and the like.
