Уровень противокоревых антител класса IgG определялся методом иммуноферментного анализа (810 чел.) и реакции пассивной гемагглютинации (170 чел.). Результаты представлены с указанием долей (%) и расчетом 95% доверительного интервала по Клопперу-Пирсону. Различия между группами оценивали с помощью критерия %2 Пирсона. Различия в группах считались статистически значимыми при уровне критерия p &lt; 0,05.</p></sec><sec><title>Результаты</title><p>Результаты: Установлено, что 8,2% персонала не защищены против коревой инфекции. При этом количество серонегативных лиц среди врачей (8,1%), среднего медицинского персонала (7,7%) и немедицинских работников (9,6%) статистически не различалось. Выявлены возрастные различия в иммунной прослойке — наибольшая восприимчивость отмечена у лиц моложе 30 лет (18,3%). Противокоревые антитела у переболевших сохранялись длительно и на высоком уровне. В то же время напряженность поствакцинального иммунитета с течением времени снижалась и через 20 лет после иммунизации значительно возросло количество серонегативных лиц. Две прививки имели только 64,1 % обследованных, более трети оказались иммунизированы однократно. Тем не менее доля незащищенных от кори лиц превышала критерий эпидемического благополучия с одинаковой частотой в обеих группах (9,2% и 1 0,4% соответственно).</p><p>Результаты серологического исследования показали, что наличие в сертификате записи о двух прививках в 9,2% случаях не гарантирует защиту при контакте с больным корью. Только серологическое обследование является доказательством наличия специфического иммунитета к коревой инфекции.</p></sec></abstract><trans-abstract xml:lang="en"><p>The measles situation is still unstable — there are imported cases, the formation of nosocomial foci with the involvement of medical personnel, patients and visitors of medical institutions.</p><sec><title>Objective of the study</title><p>Objective of the study: to assess the level of seroprevalence of primary health care workers in St. Petersburg during the period of epidemic trouble with measles.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: An open retrospective randomized uncontrolled study of the intensity of specific immunity to measles in 980 employees aged 18 to 78 years, examined in July-September 2018, was carried out. The level of anti-measles IgG antibodies was determined by the method of enzyme-linked immunosorbent assay (810 people) and passive hemagglutination reactions (170 people). The results are presented with the indication of the shares (%) and the calculation of the 95% confidence interval according to Clopper — Pearson. Differences between groups were assessed using Pearson's chi-square test (%2). Differences in the groups were considered statistically significant when the criterion level was p &lt; 0.05.</p></sec><sec><title>Results</title><p>Results: It was found that 8.2% of personnel are not protected against measles infection. At the same time, the number of seronegative persons among doctors (8.1 %), nurses (7.7%) and non-medical workers (9.6%) differed statistically. Age-related differences in the immune layer were revealed — the greatest susceptibility was observed in persons under 30 years of age (1 8.3%). Anti-measles antibodies in those who had been ill persisted for a long time and at a high level. At the same time, the intensity of post-vaccination immunity decreased over time, and 20 years after immunization, the number of seronegative individuals increased significantly. Only 64.1 % of those surveyed had two vaccinations, more than a third were immunized once. Nevertheless, the proportion of people unprotected from measles exceeded the criterion of epidemic well-being with the same frequency in both groups (9.2% and 1 0.4%, respectively).</p><p>The results of a serological study showed that the presence of a record of two vaccinations in the certificate in 9.2% of cases does not guarantee protection in case of contact with a patient with measles. Only a serological examination is evidence of specific immunity to measles infection.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>корь</kwd><kwd>иммунитет</kwd><kwd>противокоревые антитела</kwd><kwd>медицинские учреждения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>measles</kwd><kwd>immunity</kwd><kwd>measles antibodies</kwd><kwd>medical institutions</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">Griffin DE.
