Zusammenfassung:The present invention relates to a recombinant nonstructural protein 1 (NS 1), a recombinant influenza virus and an immunological composition including the same, as well as a method of treating or preventing a disease or condition caused by or associated with an influenza virus in a subject in need thereof. At least one amino acid residue is mutated or deleted in 4 contiguous amino acid residues of TRAF3-interacting motifs (TIMs) within an effector domain of the recombinant NS 1. A recombinant influenza virus including the recombinant NS1 is comparable to the wild-type influenza virus in virus replication ability, and the recombinant influenza virus can elevate interferon activation of a subject for achieving better immune response and better immunological protection, leading in a method of treating or preventing a disease or condition caused by or associated with an influenza virus in a subject in need thereof.
