    Preventive vaccination against SARS-CoV-2 infection is currently receiving close attention in the Russian Federation. Improving public confidence in immunisation with new vaccines largely depends on a guarantee of the absence of side effects caused by contamination. A high risk of contamination is inherent to biological products, including coronavirus prevention vaccines, due to their properties and the nature of raw materials used. This risk adds to the need for using effective contaminant detection approaches.The aim of the study was to evaluate the possibility to improve sterility testing of preventive vaccines against SARS-CoV-2 infection.This article presents an analysis of the procedures proposed by pharmaceutical developers for sterility testing of ten Russian vaccines approved in the country for COVID-19 prevention. The authors considered specific characteristics of these vaccines, including their physical and chemical properties, the presence of antimicrobial components, and other critical factors affecting the correctness of the experimental setup. The results suggest that it is possible to improve sterility testing. According to the authors, the main directions for its improvement are the proposal to develop an alternative procedure based on compendial method 2 (OFS.1.2.4.0003.15, Ph. Rus. XIV), as well as the use of a universal culture medium. If used for refining the established procedures and developing new ones, the authors’ recommendations will improve the reliability and applicability of sterility testing during both manufacturing and pre-approval regulatory assessment of updated coronavirus vaccines for subsequent release to the market. The proposed approaches can be applied to testing other medicinal products for sterility

    An urgent safety concern associated with biological products is contamination with mycoplasmas, which may originate from donor tissues and organs, virus harvests, culture medium components, trypsin, animal blood serum, as well as be transmitted by personnel involved in the manufacture of medicines. Currently, due to an increase in the range of biologicals available, there is a need for more sensitive and specific test methods. In the Russian practice, microbiological (culture-based) testing of finished pharmaceutical products for mycoplasma contamination is performed using complex culture media whose sensitivity depends on the quality of proteins, ingredients, and reagents used. Growth promotion properties of the media are determined according to the State Pharmacopoeia of the Russian Federation, 14th ed., using a single test strain β€” Mycoplasma arginini G230 (M. arginini G230 industry reference material). The aim of the study was to analyse current Russian and foreign requirements for the quality control of culture media that are used for mycoplasma detection, in order to update and improve the quality control procedure in Russia. It was demonstrated that a compelling advantage of the State Pharmacopoeia of the Russian Federation is the possibility of using a semi-liquid culture medium which does not require special aerobic or anaerobic incubation conditions and allows for quantification of mycoplasma colonies and determination of mycoplasma titre in culture medium while testing its growth promotion properties using reference М. arginini G230 test strain. The analysis revealed some differences in Russian and foreign requirements for quality evaluation of culture media. These differences were taken into account when developing recommendations for improvement of the Russian test procedure, i.e. enlarging the range of test strains used and development of respective reference standards.ΠΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΠΉ ΠΏΡ€ΠΎΠ±Π»Π΅ΠΌΠΎΠΉ бСзопасности биологичСских лСкарствСнных ΠΏΡ€Π΅ΠΏΠ°Ρ€Π°Ρ‚ΠΎΠ² (Π‘Π›ΠŸ) остаСтся контаминация ΠΌΠΈΠΊΠΎΠΏΠ»Π°Π·ΠΌΠ°ΠΌΠΈ, источниками ΠΊΠΎΡ‚ΠΎΡ€ΠΎΠΉ ΠΌΠΎΠ³ΡƒΡ‚ Π±Ρ‹Ρ‚ΡŒ Ρ‚ΠΊΠ°Π½ΠΈ ΠΈ ΠΎΡ€Π³Π°Π½Ρ‹ Π΄ΠΎΠ½ΠΎΡ€ΠΎΠ², вирусныС сборы, ΠΊΠΎΠΌΠΏΠΎΠ½Π΅Π½Ρ‚Ρ‹ ΠΏΠΈΡ‚Π°Ρ‚Π΅Π»ΡŒΠ½Ρ‹Ρ… срСд, трипсин, сыворотки ΠΊΡ€ΠΎΠ²ΠΈ ΠΆΠΈΠ²ΠΎΡ‚Π½Ρ‹Ρ…, Π° Ρ‚Π°ΠΊΠΆΠ΅ пСрсонал, Π·Π°Π½ΠΈΠΌΠ°ΡŽΡ‰ΠΈΠΉΡΡ ΠΈΠ·Π³ΠΎΡ‚ΠΎΠ²Π»Π΅Π½ΠΈΠ΅ΠΌ мСдицинских ΠΏΡ€Π΅ΠΏΠ°Ρ€Π°Ρ‚ΠΎΠ².

    STUDYING DEVELOPMENT OF POST-VACCINAL CELLULAR IMMUNITY AGAINST BRUCELLOSIS BY MEANS OF LYMPHOCYTE <i>IN VITRO</i> TESTS USING AN EXPERIMENTAL ANTIGENIC COMPLEX

    Regulatory framework and methodological approaches to evaluation of immunological effects of vaccination against brucellosis are not established, and the degree of immunological post-vaccinal rearrangement is not yet developed. Due to leading role of cellular immunity in formation of immune protection against brucellosis, evaluation the cellular response in response to antigenic stimulation may be considered the most informative and objective approach to analysis of immune changes in the body during vaccination. In order to develop the most diagnostically informative methods for design of antigen-stimulation cell tests in vitro, a careful selection of a stimulating agent (antigen) is required, which should have a sufficient activating potential, thus providing specificity of reaction under in vitro conditions. The aim of the present study is to study the in vitro specific activity of a protein-polysaccharide antigenic complex from the Brucella abortus 19 BA strain (BrAg), and an opportunity of its application in order to assess the formation of post-vaccinal cellular immunity against brucellosis.The study was performed with white laboratory mice (n = 50) immunized with the Brucella abortus 19 BA strain. The control group (n = 50) consisted of laboratory mice that received a sterile saline solution in a volume of 0.5 ml. Blood samples were taken from immunized and control animals before vaccination, and 7, 14, 21, and 30 days after immunization. By means of flow cytometry, the activation molecules CD25, CD69, MHC II and CD95, expressed on T lymphocytes (CD3+CD69+, CD3+CD25+, CD3+CD95+, CD3+MHC+) were determined. To observe the development of immunity, the intensity of expression of T lymphocyte activation markers was calculated using the stimulation quotient. BrAg was used for specific in vitro stimulation of T lymphocytes. The liquid brucellosis allergen (brucellin) was used as an antigen for comparison, when studying opportunity of BrAg usage for assessing the postvaccinal immunity development.The following results were obtained: BrAg has pronounced specific activity, it did not cause non-specific in vitro reactions (activation) of T lymphocytes, thus enabling its application as a test antigen when evaluating development of adaptive vaccine immunity against brucella.Experimental testing of brucellosis antigen for carrying out the in vitro antigen-stimulated cellular reactions, aiming for evaluation of post-vaccinal immunity development against brucellosis, showed that the usage of BrAg promotes increase in diagnostic sensitivity of cellular reactions under in vitro experimental conditions. The applied experimental antigen is a quite promising tool for development of laboratory algorithms for brucellosis diagnostics, and assessment of actual vaccination efficiency in cohorts previously vaccinated against brucellosis

    Sterility is one of the key parameters of biological safety of immunobiological medicinal products. The articleΒ traces the historyΒ  of the development of sterility test methods for immunobiologicalΒ  medicinal products from as farΒ back as 1961 and up to the currentΒ  requirements laid down in the State Pharmacopoeia of the RussianΒ  Federation,Β 13th edition. The article provides a detailed analysis ofΒ  major approaches to the improvement of medicinesΒ qualityΒ  evaluation based on this parameter, namely to the choice of: optimal growth media and methods of theirΒ evaluation, sensitive test strains, incubation conditions, the number of test samples (i.e., sample size)Β  requiredΒ for reliable demonstration of batch sterility; as well asΒ  approaches to the development of a test design that wouldΒ accommodate specific aspects of production and use ofΒ  immunobiological products. The article dwells upon theΒ longstanding use of the sterility testing scheme developed in the national agency for control of immunobiologicalΒ products β€” L.A.
