CONJUGATE PRODUCTION

The present invention is in the field of pneumococcal capsular saccharide conjugate vaccines. Specifically, the present invention relates to sizedserotype 6A capsular polysaccharides, in particularserotype 6A capsular polysaccharides having the average size (e.g. M) of theserotype 6A capsular polysaccharide is between 100-1000 kDa, suitably conjugated to a carrier protein.

Vaccine

The present invention is in the field of pneumococcal capsular saccharide conjugate vaccines. Specifically, an immunogenic composition for infants is provided comprising a multivalentvaccine comprising 2 or more capsular saccharide conjugates from different serotypes, wherein the composition comprises a serotype 22F saccharide conjugate. Such a vaccine may be used in infant populations to reduce the incidence of elderly pneumococcal disease such as exacerbations of COPD and/or IPD.

Pneumococcal capsular saccharide conjugate vaccine

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

Immunogenic composition

The present invention relates to a process for conjugation of an antigen.

Conjugation process

The present invention discloses an immunogenic composition comprisingcapsular saccharide conjugates from serotypes 19A and 19F wherein 19A is conjugated to a first bacterial toxoid and 19F is conjugated to a second bacterial toxoid. Vaccines, methods of making vaccines and uses of the vaccines are also described.

[object Object]

The present application discloses an immunogenic composition comprising at least 2 differentcapsular saccharides, wherein one or more is/are selected from a first group consisting of MenA, MenC, MenY and MenW which is/are conjugated through a linker to a carrier protein(s), and one or more different saccharides is/are selected from a second group consisting of MenA, MenC, MenY and MenW which is/are directly conjugated to a carrier protein(s).
