Abstrakt:	Aim: Study the effect of inactivated influenza vaccines on the activity of innate and adaptive immunity genes (TLR3, TLR4 and B2M), RNA-interference Dicer1-gene, production of cytokines (antiviral IFN type I and II, regulatory IL10, IL17) and pro-inflammatory factors IL1-β, TNFα. Materials and Methods: Gene expression was determined by rRT-PCR with authors' primers in human blood cells treated with various doses of the vaccines. Concentration of cytokines by enzyme immunoassay was measured in cultural fluid using "Vector-best" kits. Results: The studied vaccines have characteristic effects on genetic level. Grippol vaccine predominately stimulates TLR4 gene, activates TLR3, B2M and Dicer1 genes. Influvac vaccine mostly induces TLR3 gene and to a lesser extent TLR4 gene, does not influence the expression of B2M gene and inhibits Dicer1 gene. Vaxigrip split vaccine--the most potent stimulator of gene activity at low doses. Its main targets are TLR3 and B2M genes. All the inactivated vaccines--inductors of high level of IFNγ, low level of TNFα and do not induce IL17. Grippol additionally stimulates secretion of IL1-β, and Vaxigrip - IFNα. Subunit vaccines Grippol and Influvac that contain purified influenza virus hemagglutinins induce IL10 synthesis in blood cells. Conclusion: Immunogenetic characteristics of the inactivated influenza vaccines administered nowadays are obtained.
