AstraZeneca acquires Omniose to expand bacterial conjugate vaccine technology
AstraZeneca has completed its acquisition of US vaccine technology company Omniose, adding a proprietary bacterial bioconjugation platform to strengthen development of vaccines against serious infections and antimicrobial-resistant pathogens.
AstraZeneca announced on 10 November 2026 that it had acquired Omniose as a wholly owned subsidiary within its infectious disease business, bringing in a bioconjugation technology designed to link bacterial polysaccharide antigens to carrier proteins through biological manufacturing processes.
The acquisition builds on approximately three years of collaboration between the companies and expands AstraZeneca's capabilities in conjugate vaccine development for bacterial diseases and antimicrobial resistance, with financial terms undisclosed and no new vaccine regulatory approval associated with the transaction.
