Campylobacter jejuni (C. jejuni)Campylobacter jejuni (C jejuni)C. jejuniThe invention relates to immunogenic synthetic constructs capable of inducing an immune response against in a subject comprising one or more monosaccharides comprising one or more MeOPN moieties. Specifically the invention relates to immunogenic synthetic constructs capable of inducing an immune response against in a subject comprising one or more MeOPN6 Gal monosaccharides. The invention also relates to compositions comprising the immunogenic synthetic constructs and methods of inducing an immune response against in a subject comprising administering the immunogenic synthetic constructs and/or compositions comprising the immunogenic synthetic construct to the subject.
