| Abstract: | The results of the comparative analysis of the immunological effectiveness of the anti-influenza vaccine Vaxigrip, the inferferon inductor Arbidol and their combination in 125 elderly persons are presented. In the process of investigations the immunomodulating activity of the preparations under study was noted; this activity was manifested by the increase of the absolute and relative number of cells, carrying markers CD3+, CD4+ and CD16+, but not CD8+, CD19+ and CD25+, the normalization of the immunoregulatory index and the stimulation of the phagocytic function in the absence of essential influence on the level of HLA-DR+ expression and the concentration of immunoglobulins of the main classes. An increase in the frequency of seroconversions and the multiplicity of growth in the titers of specific antibodies to influenza viruses A (H1N1 and H3N2) and B, most pronounced in persons immunized with the vaccine simulianeouslywith the injection of Arbidol, was established. |
