Abstract: The invention provides a monovalent influenza vaccine comprising a low dose of egg-derived influenza virus antigen from an influenza virus strain that is associated with a pandemic outbreak or has the potential to be associated with a pandemic outbreak, in combination with an aluminium adjuvant. The invention also provides vaccine kits comprising a combination of a parenteral and a mucosal influenza vaccine, wherein the combined dose of antigen is no more than the conventional antigen dose. Also provided are methods for preparing the vaccines.

Abstract: The present invention relates to monovalent influenza vaccine formulations and vaccination regimes for immunising against influenza disease, their use in medicine, in particular their use in augmenting immune responses to various antigens, and to methods of preparation. In particular, the invention relates to monovalent influenza immunogenic compositions comprising an influenza antigen or antigenic preparation thereof from an influenza virus strain being associated with a pandemic outbreak or having the potential to be associated with a pandemic outbreak, in combination with an oil-in-water emulsion adjuvant comprising a metabolisable oil, a sterol or a tocopherol such as alpha tocopherol, and an emulsifying agent.
