COMPUTER-OPTIMIZED ANTIGENS WITH WIDE REACTIVITY SPECTRUM FOR INFLUENZA VIRUSES OF H5N1 AND H1N1 Russian patent published in 2017 - IPC C07K14/11 C12N15/44 C12N15/63 A61K39/145 A61P31/16 C12N7/04 

FIELD: biotechnology.

SUBSTANCE: recombinant influenza hemagglutinin (HA) polypeptide to elicit an immune response to the H5N1 influenza virus containing the amino acid sequence from residues 2-568 of SEQ ID NO: 1 encoding its nucleic acid containing the proposed polypeptide fusion protein and virus-like particle (VLP) to elicit a response to the H5N1 influenza virus, an expression vector containing the nucleic acid, and an isolated cell containing it, a composition and method for eliciting an immune response to the H5N1 influenza virus, and a method for immunizing a subject are proposed. The proposed group of inventions can be used in medicine for immunization against the H5N1 influenza virus.

EFFECT: proposed protein, VLP, and compositions are capable of eliciting an immune response with a wide range of reactivity to the H5N1 influenza virus.
