The survey was completed by 6032 respondents, 2114 respondents were excluded from the study. The remaining 3918 respondents were included in the the analysis.</p> <p><bold>Results. </bold>47 (0.1%) medical workers reported COVID-19 incidence within 21 days after the second dose of the vaccine. 616 (16.8%) medical workers reported COVID-19 incidence within 5 months after two vaccinations. 116 (46.4%) unvaccinated respondents reported a laboratory-confirmed new coronavirus infection within 5 months prior to the survey. Lack of vaccination increased the risk of SARS-CoV-2, OR 1.78 ± 0.14 (95% CI 1.34-2.36). It was found that gender and age were not a risk factor for the onset of the disease in the post-vaccination period. The presence of SARS-CoV-2 in medical history increased the risk of developing the disease in the post-vaccination period.</p> <p><bold>Conclusion.</bold> The analysis revealed that vaccination had significantly higher protection effect for 1.5 months after vaccination and significantly reduced in 5 months after vaccination.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель </bold>– оценка эффективности вакцинации по данным онлайн-анкетирования при использовании различных вакцин против COVID-19, разрешенных к применению в России, у медицинских сотрудников и профессорско-преподавательского состава медицинских вузов.</p> <p><bold>Материал и методы.</bold> Одномоментное онлайн-исследование проведено в период с января по март 2022 года (период циркуляции геноварианта «омикрон»). Опрос завершили 6032 респондента, из исследования были исключены 2114 опрошенных. Анализ проведен у 3918 респондентов.</p> <p><bold>Результаты.</bold> О том, что заболели в течение 21 дня после введения второй дозы вакцины, сообщили 47 (0,1%) медицинских сотрудников, после двукратной вакцинации в течение 5 мес. – 616 (16,8%). Невакцинированные респонденты сообщили, что в течение 5 мес., предшествующих опросу, перенесли лабораторно подтвержденную новую коронавирусную инфекцию – 116 (46,4%). Отсутствие вакцинации повышало риск возникновения SARS-CoV-2 ОШ 1,78±0,14 (ДИ 95% 1,34-2,36). Выявлено, что пол и возраст не являлись факторами риска возникновения заболевания в пост-вакцинальном периоде. Наличие в анамнезе перенесенной SARS-CoV-2 увеличивало риск возникновения заболевания в поствакцинальном периоде.</p> <p><bold>Выводы</bold>. Наиболее эффективную защиту вакцины обеспечивают в течение 1,5 мес. после вакцинации, и через 5 мес. после проведенной вакцинации защита снижается.</p></trans-abstract><kwd-group xml:lang="en"><kwd>coronavirus</kwd><kwd>risks</kwd><kwd>vaccination</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>коронавирус</kwd><kwd>риски</kwd><kwd>вакцинация</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kostinov MP, Polishchuk VB, Svitich OA, et al.
