Abstrakt:	Aim: To confirm and prove on the extended contingent of volunteers the non-reactogenicity, safety and immunogenicity of "Grifor" vaccine in comparative trial with registered in Russia commercial vaccine "Vaxigrip". Materials and Methods: Phase II clinical trial was performed on the research bases of Mechnikov Institute of Vaccines and Sera and Institute of Influenza. In single-blind comparative prospective randomized trial 300 adult volunteers (150 volunteers on each base) aged 18 - 60 y.o. were divided on 3 equivalent groups. Assessment of antigenic characteristics of "Grifor" vaccine was performed using hemagglutination inhibition assay (HAI) with chicken erythrocytes measuring geometric mean titer (GMT), seroconversion factor as well as level of seroconversion and seroprotection. Results: Previously performed studies proved non-reactogenicity, safety and high immunogenicity of "Grifor", whereas this comparative trial performed with commercial vaccine "Vaxigrip" did not reveal significant advantage in any of studied vaccine. Conclusion: "Grifor" vaccine meet the requirements of both EMEA CPMP and methodic guidelines MY 3.3.2. 1758-03 for inactivated influenza vaccines, which allows to register vaccine "Grifor" in Russian Federation.
