The problem to be solved: absence of safe efficient universal vaccine against influenza. The solution: The vaccine based on the fusion protein consisting of antigenic determinants of haemagglutinins of influenza A and B viruses and flagellin fragments functioning as safe adjuvant (SEQ ID NO:1) joined via flexible hinges is given which can be used for prophylaxis of influenza caused by existing influenza A and B strains as well as by possible reassortants. Safety, efficacy, polyvalence and preventive effect have been demonstrated. Usage of the present vaccine will allow to provide a universal protection against influenza.
