The amount of emulsion adjuvant required for an influenza vaccine can be reduced, thereby allowing more vaccines to be 5 made from a given amount of emulsion, and/or minimizing the amount of emulsion that has to be produced for a given number of vaccine doses. These vaccines can conveniently be made by mixing (i) an oil-in-water emulsion and (ii) an aqueous preparation of an influenza virus antigen. In one aspect, substantially equal volumes of components (i) and (ii) are used; in another aspect, an excess volume of component (ii) is used. When using substantially equal volumes, component (ii) has a 10 hemagglutinin concentration of more than 60pg per influenza virus strain per ml. Components (i) and (ii) can be presented in kit form.
