Abstract:
A low pathogenic avian influenza viral vaccine for preventing H5 subtype avian influenza viral infection is provided to enhance safety and medicinal efficacy of use, and prevent the infection of H5N1 type high pathogenic avian influenza virus safely. The method for preparing the low pathogenic avian influenza viral vaccine for preventing H5 subtype avian influenza viral infection comprises the steps of: (1) culturing a A/wild bird feces/Korea/CSM-2/02(H5N3) strain in a specific pathogen free egg(SPF egg) for 72 hours and collecting allantoic fluid; (2) measuring the titrate of the virus collected in step(1) through hemagglutination inhibition test; (3) concentrating the virus 10 times by centrifuging the virus at 18,000 rpm for 3 hours; (4) attenuating the virus by treating the concentrated virus with 0.1% formalin at 20 deg.C for 12 hours; and (5) mixing the attenuated virus solution with oil adjuvant ISA70 in a weight ratio of 3:7, wherein the low pathogenic avian influenza viral vaccine contains at least one protein encoded by the gene of SEQ ID NO:2 to SEQ ID NO:9.

Abstract:
The present invention relates to an influenza monovalent vaccine having a broad defending activity, or an influenza supplementary vaccine using the same. The influenza monovalent vaccine or influenza supplementary vaccine of the present invention increases the immunity against an M2e protein for influenza virus infection of various serotypes, thereby having a broad defense ability effectively responding to the unforeseen spread of virus like national epidemic.
Abstract:
Provided are: a method for improving immunogenicity of a HA2 common epitope of influenza virus by replacing asparagine, which is the 154th amino acid, and serine (S) or threonine (T), which is the 156the amino acid, with other amino acid such that N-glycan generation does not occur at asparagine (N), which is the 154th amino acid, of a HA2 fragment derived from a HA amino acid of avian influenza virus; and a recombinant virus with improved immunogenicity through the method. The technic for improving immunogenicity of a HA2 common epitope and the HA2 common epitope high immunogenicity virus of the present invention can be effectively used in developing a vaccine strain for preventing influenza and effectively used as a vaccine strain.
Abstract:
The present invention relates to: a composition for high productiveness of an embryonated egg of H1N1 family avian influenza and non-pathogenicity of a mouse including, as a active ingredient, a polynucleotide encoding a PB2 protein of a low pathogenic avian influenza virus; a recombinant expression vector including the polynucleotide; an attenuated recombinant virus transformed into the expression vector; and a vaccine composition including the recombinant expression vector. The recombinant expression vector of the present invention enhances chicken embryo productivity of a vaccine strain for preventing influenza, and thereby, having advantages of being capable of being effectively used in enhancing efficacy and productivity of killed vaccines, and additionally, has no pathogenicity for mice and has immunogenicity, and thereby having advantages of being capable of being effectively used as live vaccines.
