Abstract: An antigenic short peptide includes 11 to 15 amino-acid residues and has an ability to induce antibody against influenza virus. The sequence of the antigenic peptide is selected from hemagglutinin (HA). The antigenic peptide includes the sequence of JJ (SEQ ID NO:2), JJ-1 (SEQ ID NO:3), JJ-2 (SEQ ID NO:4), JJ-3 (SEQ ID NO:5) or JJ-4 SEQ ID NO:6). A method for inducing a broad-spectrum immunity against influenza viruses includes administering a vaccine to a subject, wherein the vaccine comprises one of the above antigenic peptide.
