摘要
During the twentieth century the world faced four influenza A pandemics: A (H1N1) in 1918, A (H2N2) in 1957, A (H3N2) in 1957 and A (H1N1) recirculation in 1977. In the beginning of 2009 the global spread of A(H1N1)pdm2009 virus was detected. In consideration of clinical evidences and genetic data analysis WHO declared as the novel pandemic of 21th century. However, the fact of exceedingly prolonged previous worldwide circulation of A (H1N1) influenza viruses was not taken into account. Further development showed epidemiological prognosis not to be accurate enough. The present work is an attempt to analyze this question from the immunological standpoint based on our studies of antibody and cellular immunity to A(H1N1)pdm2009 virus in vaccinated and non-vaccinated persons of different ages. The study results allow concluding that A(H1N1)pdm2009 is the drift variant of A (H1N1) viruses antigenically close to A/Swine/1976/1931 (H1N1). It was shown that the significant of persons have cross-reactive B and T cell immunological memory to A(H1N1)pdm2009 strain. This could be a reason of decreased A(H1N1)pdm2009 pandemic severity.
