The present invention addresses an ongoing need in the art to improve the stabilityof immunogenic compositions such as polysaccharide-protein conjugates andprotein immunogens. The invention broadly relates to novel formulations whichstabilize and inhibit precipitation of immunogenic compositions. More particularly,the invention described hereinafter, addresses a need in the art for formulationswhich stabilize and inhibit particulate formation (e.g., aggregation, precipitation)of immunogenic compositions which are processed, developed, formulated, manufacturedand/or stored in container means such as fermentors, bioreactors, vials, flasks,bags, syringes, rubber stoppers, tubing and the like.
