The immunogenicity of Pandeflu subunit vaccine against influenza A/California/7/2009 (H1N1) was evaluated in 70 healthy volunteers aged 18 to 60 years. The vaccine was intramuscularly injected twice at an interval of 28 days. Each dose (0.5 ml) contains A(HIN1) influenza virus hemagglutinin (15 +/- 2.2 microg), aluminum hydroxide (Denmark) (0.475 +/- 0.075 microg), and the preservative thiomerosal (merthiolate) (50 +/- 7.5 microg). The level of antibodies was determined in the microneutralization assay. After administration of two doses of the vaccine at a 28-day interval, the geometric mean antibody titer (GMAT) reached 1:21.1 with a further increase to 1:30 (the baseline GMAT) was 1:6.1). The frequencies of seroconversion and seroprotection were 71.4 and 59.2%, respectively; the antibody increase factor was 4.92, which meets the CPMP criteria. The administration of the vaccine did not result in adverse reactions in the postvaccination period.

D007252 Influenza Vaccines Vaccines used to prevent infection by viruses in the family ORTHOMYXOVIRIDAE. It includes both killed and attenuated vaccines. The composition of the vaccines is changed each year in response to antigenic shifts and changes in prevalence of influenza virus strains. The flu vaccines may be mono- or multi-valent, which contains one or more ALPHAINFLUENZAVIRUS and BETAINFLUENZAVIRUS strains.
