The disclosure describes compositions containing conjugates using novel linkers, bivalent polysaccharide conjugates, and methods of bivalent polysaccharide conjugation in the development of multivalent conjugate vaccines. Conjugation of capsular polysaccharides to carrier proteins is carried out using homo-bifunctional and / or hetero-bifunctional linkers of specific lengths.
