Исследовано 1835 образцов сыворотки крови. Ни один из образцов не реагировал в РТГА с высокопатогенными вирусами A(H5N8) и A(H7N9). От 41 до 58% образцов сывороток в зависимости от региона сбора имели значимые титры антител (40 и выше) против вакцинного штамма A/Michigan/45/2015 (H1N1pdm09). 40-63% тех же сывороток были положительными к эпидемическому штамму A/Lipetsk/1V/2018 (H1N1pdm09), выделенному в начале эпидемического сезона (26.11.2018). От 26 до 46% образцов были серопозитивными в отношении вакцинного штамма A/Singapore/INFIMH-16-0019/2016 (H3N2) и от 10 до 23% — в отношении вируса гриппа B генетической линии Ямагата. В эпидемическом сезоне 2018-2019 гг. тяжелые случаи гриппа вызывали в основном вирусы гриппа А с преобладанием штаммов A/H1N1pdm09 (52,5%). На долю вирусов гриппа В пришлось 3% заболеваний. Было подтверждено 217 случаев гриппа со смертельным исходом, из них около половины (44,7%) заболеваний пришлось на возрастную группу людей 60 лет и старше, 29% — на возрастную группу 46-59 лет. Восемь случаев (3,7%) смерти от гриппа были зафиксированы у вакцинированных гриппозной вакциной накануне эпидсезона. Более 75% умерших от гриппа имели сопутствующие заболевания, наиболее распространенные среди них — сердечно-сосудистые, ожирение, диабет, заболевания мочевыделительной системы, инфекционные болезни (ВИЧ, гепатиты). Таким образом, в профилактике гриппа вакцинация остается самым эффективным средством, особенно это касается групп риска. Исследование проводилось в рамках выполнения государственного задания ГЗ-1/16 и ГЗ-2/18.</p></abstract><trans-abstract xml:lang="en"><p>The aim of our work was to investigate the herd immunity to influenza viruses among population of Russia during autumn 2918; evaluation of severe cases of the infection over the season of2018-2019 epidemics, and confirmed cases of influenza in vaccinated persons. A total of 1835 samples of blood serum were studied. Neither sample did react in hemagglutination inhibition test with highly pathogenic A(H5N8) and A(H7N9) viral strains. 41 to 58% of samples, dependent on sampling region, showed significant antibody titers (&gt; 40) against против вакцинного штамма the vaccinal A/Michigan/45/2015 strain (H1N1pdm09). 40 to 63% of the same sera were positive for epidemic A/Lipetsk/1V/2018 strain (H1N1pdm09), isolated at the start of epidemic season (26.11.2018). From 26 to 46% of the samples were seropositive towards vaccinal strain A/Singapore/ INFIMH-16-0019/2016 (H3N2), and 10 to 23% towards Yamagata influenza B genetic strain. Severe influenza cases during the 2018-2019 epidemic season were caused, mainly, by influenza A virus, with predominance of A/H1N1pdm09 (52.5%), with only 3% of cases caused by influenza A viruses. 217 cases of influenza with lethal outcome were confirmed, of them about a half of these cases (44.7%) affected older persons (&gt; 60 years old), 29% were diagnosed in the group of 46-59 years old. Eight lethal cases of influenza infection (3.7%) were documented in the persons vaccinated before the vaccination season. Over 75% of patients with lethal influenza cases had concomitant diseases, with cardiovascular disorders, obesity, diabetes, urogenital diseases, infectious diseases (HIV, hepatitis) being most often. Hence, vaccination against influenza remains the most effective protective tool, especially in the risk groups. The study was performed in the frames of the state task contract (ГЗ-1/16 and ГЗ-2/18).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вирус гриппа</kwd><kwd>популяционный иммунитет</kwd><kwd>реакция торможения гемагглютинации</kwd><kwd>защитные титры антител</kwd><kwd>смертность от гриппа</kwd><kwd>группы риска</kwd></kwd-group><kwd-group xml:lang="en"><kwd>influenza virus</kwd><kwd>herd immunity</kwd><kwd>hemagglutination inhibition test</kwd><kwd>antibody protective titers</kwd><kwd>influenza death rate</kwd><kwd>risk groups</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование проводилось в рамках выполнения государственного задания ГЗ-1/16 и ГЗ-2/18</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Коллегия Роспотребнадзора по итогам эпидсезона гриппа и ОРВИ 2018-2019 гг.
