    摘要: This invention provides a novel immunogenic composition and vaccine, processes for producing them and methods for immunization against infections and disease caused by group A Streptococci. The compositions include group A streptococcal polysaccharide covalently linked to protein or liposomes to form immunogenic conjugates. The method of immunization for this invention comprises administering to an individual an immunogenic amount of group A polysaccharide. The group A polysaccharide may be administered as a vaccine either on its own, conjugated to proteins or conjugated to liposomes. Additionally, the group A polysaccharides may be associated with an adjuvant. This invention is particularly useful for providing both active and passive immunogenic protection for those populations most at risk of contracting group A Streptococcal infections and disease namely adults, pregnant women and in particular infants and children.

    摘要: A system and method for assessing immunological status of individuals and populations is presented. The method includes establishing a database containing a plurality of records, each record containing information representative of the immune status of an individual, including (1) bioassay results, and (2) individual specific information such as, medical history, clinical observations and historical, demographic, lifestyle, and familial/genetic information. By processing the information trends and/or patterns are obtained correlating various variables in the records across an individual, population or sub-population. The identified trends and/or patterns can, for example, be used in health care related decision making. In exemplary embodiments such processing can include generating a set of correlations and for each correlation generating a set of explanatory or relevant hypotheses. Then, for example, each hypothesis can be automatically refuted or supported, to the extent possible. The identified correlations, their associated hypotheses and the results of such automated vetting can then be reported to a user.

    摘要: This invention relates to modified pneumolysin polypeptides that retain the immunogenic nature of pneumolysin but have reduced or undetectable hemolytic activity compared to native pneumolysin. The invention also provides a method for generating novel pneumolysin variants with these desired characteristic properties. The invention also provides immunogenic compositions useful as pharmaceutical compositions including vaccines in which non-toxic, modified pneumolysin is used to stimulate protective immunity against Streptococcus pneumoniae. The vaccines may be compositions in which the modified pneumolysin is conjugated to bacterial polysaccharides or may be carried on an attenuated viral vector. In addition, the invention also provides a method of using the non-toxic, modified pneumolysin toxoid in order to stimulate antibodies against Streptococcus pneumoniae in a treated individual which are then isolated and transferred to a second individual, thereby conferring protection against Streptococcus pneumoniae in the second individual.

    摘要: The present invention relates to methods of manufacture of immunogenic glycoconjugates, in particular for use in pharmaceutical compositions for inducing a therapeutic immune response in a subject. The immunogenic glycoconjugates of the invention comprise one or more oligosaccharides or polysaccharides that are conjugated to one or more carrier proteins via an active aldehyde group. Accordingly, the invention provides methods of making (i) unsaturated microbial N-acyl derivative oligosaccharides or polysaccharides; (ii) novel conjugates of unsaturated N-acyl derivatives; and (iii) glycoconjugate compositions comprising conjugate molecules of fragments of microbial unsaturated N-acyl derivatives that serve as a covalent linker to one or more proteins. The invention further encompasses the use of the immunogenic glycoconjugates pharmaceutical compositions for the prevention or treatment of an infectious disease.

    摘要: Neisseria meningitidis group B polysaccharide (GBMP) modified by having sialic acid residue N-acetyl groups replaced by N-acyl groups exhibits enhanced immuno response thereto. In addition, induction of antibodies which cross-react with unmodified group B meningococcal and E. coli K1 capsular polysaccharide and other tissue cells having a common epitope is minimized. Conjugation of the modified polysaccharides with a physiologically acceptable protein such as tetanus toxoid induces the production of specific protective antibodies with negligible levels of GBMP-cross reactive antibodies, to thereby afford protection against infections caused by group B meningococci and E. coli K1.
