Abstract
The present invention relates to a versatile influenza virus vaccine composition using the HA2 helical domain of a hemagglutinin protein, which is an influenza surface protein, and to a pharmaceutical composition for preventing or treating influenza virus infectious diseases. The polypeptide expressed by SEQ ID NO: 3 and the polypeptide expressed by residues 379 to 474 of SEQ ID NO: 1 of the present invention can be mass-produced in, and effectively produce neutralizing antibodies to various influenza virus subtypes, and thus the polypeptides can be widely utilized as versatile vaccines for influenza virus subtypes and new influenza virus variants.
