Изготовление промышленных серий вакцины БЦЖ проводят в рамках системы «посевной серии» (seed-lot system), которая регламентирует изготовление вводимой в гражданский оборот вакцины из единой серии посевного материала — лиофилизата Mycobacterium bovis BCG. Оценка посевного материала вакцины БЦЖ по показателям качества в отечественных и зарубежных документах представлена в виде отдельных небольших разделов, содержащих краткое описание и/или перечисление показателей и методов контроля. Объединить информацию о получении, аттестации и хранении посевного материала (посевной серии) для производства отечественной вакцины БЦЖ является актуальной задачей. Цель работы — провести сравнительную оценку основных характеристик и методов контроля посевного материала отечественного субштамма M. bovis BCG-I (Russia), изложенных в национальных и международных требованиях к вакцинам БЦЖ. Обобщены данные литературы по истории появления субштаммов M. bovis BCG, вариабельности их характеристик, представлена краткая история происхождения отечественного субштамма BCG-I. Рассмотрены методы контроля, указанные в национальных и международных требованиях к посевному материалу вакцины БЦЖ. Показана практическая возможность провести индикацию субштамма M. bovis BCG-I (Russia) с последующим определением генетических свойств, характеризующих его геномную стабильность. Приведены результаты сравнительного анализа данных о стабильности лиофилизатов посевных серий M. bovis BCG-I (Russia). Особое внимание уделено биологическим методам контроля посевной серии: определению остаточной вирулентности, включая приживаемость, и иммунобиологическому методу контроля БЦЖ на отсутствие генов, ответственных за выработку антигенов вирулентности (кожные пробы на животных с препаратом Диаскинтест®). Сделан вывод о том, что контроль стабильности генетических и биологических свойств на протяжении всего периода производства и хранения посевной серии позволяет получать вакцину БЦЖ, соответствующую всем требованиям нормативной документации.</p></abstract><trans-abstract xml:lang="en"><p>To date, the Bacillus Calmette–Guérin (BCG) vaccine has been the only medicinal product for active mass childhood immunisation against tuberculosis in the Russian Federation. Industrial-scale batches of the BCG vaccine are manufactured using a seed-lot system, which provides for producing the vaccine for civil circulation from a single batch of seed material, a lyophilisate of Mycobacterium bovis BCG. National and international documents touch upon the evaluation of BCG vaccine seed material in terms of its quality attributes in small separate sections containing brief descriptions and/or lists of attributes and control methods. It is relevant to bring together the information on receipt, certification, and storage of the inoculum (the seed lot) for production of the Russian BCG vaccine. The aim of the study was a comparative assessment of the main characteristics of and control methods for the inoculum of the Russian vaccine strain, M. bovis BCG-I, set out in the national and international requirements for BCG vaccines. The article summarises literature data on the history of BCG substrains and the variability of their characteristics and presents a brief account of the origin of the Russian BCG-I substrain. It considers the control methods specified in the national and international requirements for the inoculum for the BCG vaccine. The study demonstrated the practical possibility of identifying BCG down to the substrain level with subsequent determination of genetic properties that characterise genomic stability of the substrain. The article presents the results of the comparative analysis of data on stability of lyophilisates of M. bovis BCG-I seed lots (Russia). Particular attention is paid to biological methods for controlling the seed lot (determination of residual virulence, including BCG survival) and the immunobiological method for controlling BCG for the absence of the genes responsible for virulence antigen expression (animal skin tests with Diaskintest®). The authors concluded that the control of stability of genetic and biological properties throughout the entire period of seed lot production and storage makes it possible to obtain BCG vaccines that meet all the regulatory requirements.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вакцина БЦЖ</kwd><kwd>посевная серия</kwd><kwd>субштамм</kwd><kwd>cистема посевных серий (seed-lot system)</kwd><kwd>стабильность генома</kwd></kwd-group><kwd-group xml:lang="en"><kwd>BCG vaccine</kwd><kwd>seed lot</kwd><kwd>substrain</kwd><kwd>seed-lot system</kwd><kwd>genome stability</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках государственного задания ФГБУ «НЦЭСМП» Минздрава России № 056-00001-22-00 на проведение прикладных научных исследований (номер государственного учета НИР 121022000147-4)</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study reported in this publication was carried out as part of publicly funded research project No. 056-00001-22-00 and was supported by the Scientific Centre for Expert Evaluation of Medicinal Products (R&amp;D public accounting No. 121022000147-4)</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">Вакенгут АМ, Доликов КЕ, Лещинская ЕН.
