PURPOSE: A recombinant baculovirus is provided to protect a swinery from novel swine-origin influenza A(H1N1) and to prevent new or variant virus expressed in a pig.CONSTITUTION: A recombinant baculovirus is prepared by inserting a gene which expresses HA(hemagglutinin), a gene which expresses NA(neuraminidase), and a gene which expresses M1(matrix 1) protein. The HA expressing gene is a gene(GeneBank FJ966082) which expresses HA of influenza virus A/California/04/2009(CA09). The NA expressing gene is a gene(GeneBank FJ966084) which expresses NA of influenzavirus A/California/04/2009(CA09). The M1 protein expressing gene is a gene(GeneBank FJ969513) which expresses M1 protein of influenza virus A/California/04/2009(CA09). A VLP(Virus-Like Particle) for suppressing swine influenza viral infection contains the recombinant baculovirus. A vaccine for suppressing swine influenza viral infection contains the VLP.COPYRIGHT KIPO 2013[Reference numerals] (AA) Tn7L,Tn7R sequence homologous recombination for Baculovirus본 발명은 신종인플루엔자 바이러스 헤마글루티닌(Hemagglutinin), 뉴우라미니데이즈(Neuraminidase) 및 매트릭스1(Matrix1) 단백질을 발현하는 유전자를 베큘로바이러스에 삽입한 후 세가지 단백질로 구성된 신종인플루엔자 바이러스 유사입자(virus like particle)을 합성하여 부형제를 첨가하여 돼지에 접종 후 돼지가 신종인플루엔자 바이러스에 감염되는 것을 억제하는 성질을 가진 백신 조성물에 및 그 효능 입증에 관한 것이다.
