РОЛЬ БИОБАНКОВ В ИЗУЧЕНИИ ПОПУЛЯЦИОННОГО ИММУНИТЕТА

Review focuses on estimation of population immunity and  effectiveness of vaccination against socially significant influenza  infection. Long-term observations of the population immunity,  including post-vaccine seroprevalence to influenza are an important  component of surveillance. The possibility of use of systems of  biological banks (biobanks) in these investigations is of great  interest. The data on the principles of biobanks design in the world,  the scope of their application, the present state of the industry are  described. The information about collections of infectious diseases  agents is presented. Suggestions to build a network of biobanks in the Russian Federation and its implementation in the system of  epidemiological influenza surveillance are formed. The biobanks  filling by samples, principles of selection of donors biological  specimens, methods of laboratory research are discussed.Обзор посвящен оценке популяционного иммунитета и эффективности вакцинации против  грипп. Многолетние наблюдения за коллективным (популяционным) иммунитетом, включая  поствакцинальный, при гриппе остаются важной составляющей эпидемиологического надзора. Новые возможности в исследовании популяционного  иммунитета открываются с созданием системы биологических банков (биобанков).  Приводятся данные по принципам построения биобанков в мире, сферы их применения,  современное состояние данной отрасли. Представлены сведения о коллекциях возбудителей инфекционных заболеваний. Даны предложения по построению сети  биобанков в Российской Федерации с внедрением в систему эпидемиологического надзора  за вирусными заболеваниями. Обсуждается структура наполняемости биобанков образцами, принципы подбора доноров биологических образцов,  методы их лабораторного изучения

Immunogenicity of Modern Vaccine Viruses of Influenza A (H1N1)pdm09 According to Graphical Analysis

Antiepidemic measures were limited effectiveness for several years Objectives of this research were formulated as an assessment of the immunogenicity activity of the influenza virus A(H1N1)pdm09 in the composition of modern trivaccines Immunogenicity of the influenza virus A(H1N1)pdm09 in the vaccinated by vaccine was assessed by graphing, reflecting the dynamics of the multiplicity growth of antibodies (MG) and medium ratio of antibodies increasing (MR) in sera for several groups vaccinated. For comparison of vaccinated immunity was determined by traditional methods of evaluation of the immune response. As a result of the research, differences in the immunogenicity activity of the virus were revealed, which are reflected in antibody titers and the multiplicities of their growth from 2 to 4 - 8 times with the applying of similar quality vaccines. These changes couldn’t be observed with accounting study of the immune response. When immunized with a vaccine with an antigen dose of 5 mg HA identified a group of«silent» volunteers (8%) who did not respond to promotion with antigen A(H1N1)pdm09. Increasing dose of the influenza virus A(H1N1)pdm09 to 15 mg/dose in the split vaccine were result of the elimination of the group of«silent» volunteers. Simultaneously was observed a significant increase in the immune response in serum titers (up to 32-fold) and antibody growth rates Accordingly, using of the graphical form of accounting made it possible to better assess the details of the formation of collective immunity to the virus A(H1N1)pdm09 and the nature of its deviations in a number of cases
