摘要:
Streptococcus pneumoniae is a major health concern, especially in very young, elderly, or immunocompromised patients. The present disclosure provides, inter alia, certain highly effective vaccines and pharmaceutical compositions in Streptococcus pneumoniae. The antigens may be used therapeutically or prophylactically.

摘要:
The present embodiments provide for an immunogenic multiple antigen presenting system comprising a polymer to which antigens are associated by complementary affinity molecules. For example, the polymer can be a polysaccharide, or antigenic polysaccharide, to which protein or peptide antigens from the same or different pathogens are indirectly linked. The present immunogenic compositions can elicit both humoral and cellular immune responses to one or multiple antigens at the same time.

摘要:
The present application is generally directed to novel pneumococcal polypeptide antigens and nucleic acids encoding such antigens, and immunogenic compositions comprising such antigens for treating and preventing pneumococcal infection. The present invention further provides method of using the antigens to elicits an immune response (e.g., IL-17A response, a T cell-mediated and/or B-cell-mediated immune responses). The present invention also provides methods of prophylaxis and/or treatment of pneumococcal-mediated diseases, such as sepsis, comprising administering an immunogenic composition including one or more of a combination of pneumococcal antigens or functional fragments thereof as disclosed herein. In some embodiments, one or more pneumococcal antigens can be present in a polysaccharide conjugate. The compositions induce an anti-pneumoccocus immune response when administered to a mammal. The compositions can be used prophylactically to vaccinate an individual and/or therapeutically to induce a thereapeutic immune response to an infected individual.

Streptococcus pneumoniae is a major health concern, especially in very young, elderly, or immunocompromised patients. The present disclosure provides, inter alia, certain highly effective vaccines and pharmaceutical compositions in Streptococcus pneumoniae that contain fusion proteins. The antigens may be used therapeutically or prophylactically.
摘要:
The present invention provides for immunogenic compositions and methods for producing an immunogenic composition with multiple immunity-inducing fractions of killed, whole-cell Streptococcus pneumoniae by selectively disrupting a whole cell bacterial preparation in such a manner that a soluble fraction that induces a primarily antibody response, and a cellular fraction that induces a primarily antibody-independent response, remain in the immunogenic composition.
摘要:
An immunogenic composition comprising a fusion protein-polysaccharide conjugate consisting of a polysaccharide (PS) or pneumococcal bacterial cell wall polysaccharide (CWPS) conjugated to X:PdT where PdT represents the nonhemolytic variant of pneumolysin and X represents an antigenic peptide or protein of interest is provided. The immunity to X is synergistically enhanced by the fusion conjugate. Methods of protecting a subject from pneumococcal colonization or disease by administering an immunogenic composition including a fusion protein (PsaA:PdT) containing truncated PsaA and the nonhemolytic variant of pneumolysin (PdT) conjugated with CWPS (PsaA:PdT-CWPS) is also provided.
