AIM: Study subpopulation structure of lymphocytes in healthy individuals under the effect of various influenza vaccines in an in vitro system. MATERIALS AND METHODS: Evaluation of immune- phenotype features of PBMCs, activated in vitro by immune-adjuvanted and unadjuvanted vaccines against influenza in healthy individuals, was carried out by using flow cytometry method. RESULTS: Grippol plus vaccine caused a more pronounced stimulating effect compared with subunit and split-vaccines on NK-cells, cells with markers of early activation CD45/CD25, induced the quantity of natural regulatory cells (CD4/CD25/Foxp3), increase of the number of B-cells and reduced the amount of cell types with apoptosis marker CD45/CD95. CONCLUSION: Immune-adjuvanted vaccine Grippol plus induced formation of effectors of both innate and adaptive immunity and possessed the most powerful potential regarding activation of various types of immune-competent cells compared with unadjuvanted vaccines.
