The humoral response to SARS-CoV-2 infection (the production of antibodies that intercept the virus and prevent it from infecting the cell) has been well-studied; however T-cell response is not. Nevertheless, it is T-lymphocytes that not only detect and destroy infected cells, but also affect long-term immune memory. How is T-cell immunity tested? Are there any differences in its development in people who have had COVID-19 and those who have been vaccinated? Will vaccines created for the original SARS-CoV-2 protect against mutants? Grigorii Aleksandrovich Efimov, Candidate of Biological Sciences, Head of the Laboratory of Transplant Immunology at the National Medical Research Center for Hematology answers these and other questions.</p></abstract><trans-abstract xml:lang="ru"><p>В ответ на коронавирусную инфекцию, как и на любую другую, наш организм мобилизует две системы иммунной защиты — антитела и Т-лимфоциты, или Т-клетки. Гуморальный ответ на инфекцию SARS-CoV-2 (выработка антител, которые перехватывают вирус и не позволяют ему заразить клетку) изучен довольно хорошо, чего не скажешь про Т-клеточный*. Однако именно Т-лимфоциты не только обнаруживают и уничтожают инфицированные клетки, но и влияют на долговременную иммунную память. Как исследуют Т-клеточный иммунитет? Есть ли отличия в его формировании у людей, переболевших COVID-19, и вакцинированных? Защитят ли вакцины, созданные к изначальному варианту SARS-CoV-2, от его мутантов? На эти и другие вопросы ответил кандидат биологических наук Григорий Александрович Ефимов, заведующий лабораторией трансплантационной иммунологии Национального медицинского исследовательского центра гематологии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>SARS-CoV-2</kwd><kwd>COVID-19</kwd><kwd>SARS-CoV-2</kwd><kwd>COVID-19</kwd><kwd>T-cell immunity</kwd><kwd>S-protein</kwd><kwd>vaccination</kwd><kwd>test system</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Т-клеточный иммунитет</kwd><kwd>S-белок</kwd><kwd>вакцинация</kwd><kwd>тест-система</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Shomuradova A.S., Vagida M.S., Sheetikov S.A., Efimov G.A.
