    Abstract: The invention provides a process for preparing a conjugate of a S. aureus type 5 or type 8 capsular polysaccharide and a carrier molecule, comprising the steps of: (a) depolymerizing the capsular polysaccharide, to give a polysaccharide fragment; (b) oxidizing the fragment in order to introduce an aldehyde group into at least one saccharide residue in the fragment, to give an oxidized saccharide residue; and (c) coupling the oxidized saccharide residue to a carrier molecule via the aldehyde group, thereby giving the conjugate. The coupling in step (c) may be direct, or may be via a linker molecule. The invention also provides a conjugate obtained or obtainable by this process.

    Abstract: The invention is directed to compositions and methods for generating or enhancing the immune system of a patient against infection by a pathogen, and in particular MTB. Compositions of the invention contain one or more non-naturally occurring antigens that generate an effective cellular or humoral immune response to MTB and/or antibodies that are specifically reactive to mycolic acid or to the surface of MTB. The greater activity of the immune system generated by a vaccine of the invention involve an conjugation of peptides to increase in the generation of memory T cells that provide for a greater and/or longer lived or extended response to an MTB infection. Preferably a response involves an increased generation of antibodies that enhance immunity against MTB infection and promote an enhanced phagocytic response.
