Abstract: The present disclosure relates to vaccine compositions comprising a) antigens from at least three different strains of influenza vims, preferably at least four different strains of influenza vims, and b) an oil-in-water emulsion adjuvant, wherein the amount of the oil-in-water emulsion adjuvant is greater than an amount of an oil-in-water emulsion adjuvant in a standard-dose adjuvanted multivalent influenza vaccine. Additionally, the total amount of the antigens in the vaccine compositions may be greater than a total amount of antigens in a standard-dose adjuvanted multivalent influenza vaccine. In preferred aspects, the present disclosure further describes uses of these vaccine compositions for safe and effective induction of immune responses in adults at least 65 years of age.
