The invention relates to an immunogenic composition, capable of inducing protective antibodies against Helicobacter infection, characterised in that it comprises: i) at least one sub-unit of a urease structural polypeptide from Helicobacter pylori, or a fragment thereof, said fragment being recognised by antibodies reacting with Helicobacter felis urease, and/or at least one sub-unit of a urease structural polypeptide from Helicobacter felis, or a fragment thereof, said fragment being recognised by antibodies reacting with Helicobacter pylori urease; ii) optionally, a urease-associated Heat Shock protein (HSP), or chaperonin, from Helicobacter, or a fragment of said protein. |
