The problem of increasing the population antiviral immunity is of particular importance during the third year of the SARS-CoV-2 pandemic. Concomitant intestinal dysbiosis is known to play an significant role in immune cell dysfunction. Therefore, it is very important to take measures to maintain the gut microbiota using the most affordable nutritional remedies, which include fermented milk and probiotic products designed for mass population consumption and capable of enhancing their immune defence when added to the daily diet. The aim of the study was to analyze scientific evidence highlighting the role of intestinal microbiota in maintaining the macro-organism immunological balance, and to evaluate modern fermented milk and probiotic products in terms of their effect on normalising the gut microbiota and their importance in the prevention and treatment of SARS-CoV-2. Material and methods . The presented scientific and analytical review analyzed the data of electronic resources of the Global Health platform, scientific libraries eLIBRARY.RU, Cochrane Library and CyberLeninka, the search system Google Academy», specialized sites for scientific publications ScienceDirect and Elsevier, bibliographic databases of articles on medical sciences MEDLINE, CDC infection diseases, Embase and PubMed- NCBI. The structural-logical, analytical and axiomatic methods were used. Results . It has been shown that normal intestinal microbiota takes part in maintaining metabolism in the digestive tract, increases the body's immune reactivity and regulates the functioning of all organs and systems. The severity of dysbiotic disorders can determine susceptibility to SARS-CoV-2, the severity of this infection course, as well as the level of post-infection and post-vaccination anti-COVID-19 immunity. The high prevalence of gut dysbacteriosis indicates the need to strengthen measures of correcting dysbiotic disorders, including the inclusion of fermented and probiotic products in the daily population diet. Conclusion . Fermented milk and probiotic products, as sources of easily digestible macronutrients, essential micronutrients, biologically active substances and beneficial live microorganisms, should be included in the daily diet during the SARS-CoV-2 pandemic to increase the adaptive capacity and immunity of the population.
