Выявить различия в течении COVID-19 у вакцинированных и невакцинированных лиц пожилого и старческого возраста.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведен анализ заболеваемости COVID-19 у 1126 пациентов, госпитализированных в один из московских стационаров с 23.06.2021 г. по 01.05.2022 г. Участники исследования были разделены на две когорты: вакцинированные – 538 человек (47,80%) и невакцинированные – 588 человек (52,2%). Средний возраст у вакцинированных – 68,73 ± 0,61 лет, у невакцинированных – 66,69 ± 0,66 года (p &lt; 0,05).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Было установлено, что риск заболеть COVID-19 у неиммунизированных в 1,5 раза выше, чем у вакцинированных (p &lt; 0,05). Летальность у вакцинированных смещается на старческий возраст (76,93 ± 1,32), у непривитых – ближе к категории пожилой возраст (73,74 ± 1,39 лет) (p ≤ 0,05). В структуре летальности среди вакцинированных основную долю составляли пациенты, имевшие в анамнезе от 3 до 7 сопутствующих заболеваний (66,7%), тогда как среди непривитых основную долю (74,5%) составляли пациенты либо без коморбида, либо, имевшие в анамнезе от 1 до 2 сопутствующих заболеваний.</p></sec><sec><title>Выводы</title><p>Выводы. Результаты исследования показали, что для лиц пожилого и старческого возраста, особенно с коморбидными состояниями, вакцинация против вируса SARS-CoV-2 является жизненно необходимой.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. COVID-19 vaccination reduces mortality and the course of severe diseases. However, there is an insufficiency of studies evaluating factors leading to infection among COVID-19 vaccinated individuals.</p></sec><sec><title>Aim</title><p>Aim. Identification of epidemiological features that distinguish cases of the disease in vaccinated and unvaccinated cohorts.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The analysis of the incidence of COVID-19 in 1126 hospitalized patients in the period from 23.06.2021 to 01.05.2022 was carried out taking into account the presence or absence of vaccination against the SARS-CoV-2 virus.</p></sec><sec><title>Results</title><p>Results. It was found that the risk of COVID-19 getting sick in the unimmunized was 1.5 times higher than in the vaccinated (p &lt; 0.05). The incidence of hospitalization, due to the severity of the condition (moderate, severe and extremely severe), in unvaccinated people with no history of comorbidities, is more than 3 times higher than in vaccinated people (p &lt; 0.05) in the same group. The probability of death from COVID-19 among vaccinated people is 1.5 times lower than among unimmunized people (p &lt; 0.05). The age characteristic of mortality in vaccinated people shifts to the «senile» age (76.93 ± 1.32), while among the unimmunized, the age of death is closer to the category of «elderly» (73.74 ± 1.39 years) (p ≤ 0.05). In the structure of mortality among the vaccinated, the main share was made up of patients with a history of 3 to 7 concomitant systemic diseases (66.7%), while among the unvaccinated, the main share (74.5%) were patients either without comorbidities or with a history of 1 to 2 concomitant diseases.</p></sec><sec><title>Conclusion</title><p>Conclusion. The results of the epidemiological features of the COVID-2 epidemic process have shown that vaccination against the SARS-CoV-2 virus is vital for elderly and senile people with comorbid conditions.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>вакцинация COVID-19</kwd><kwd>заболеваемость привитых</kwd><kwd>летальность привитых</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19 vaccination</kwd><kwd>morbidity of vaccinated people</kwd><kwd>lethality of vaccinated people</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Lipsitch M., Swerdlow D.L., Finelli L.
