The syndrome called VITT (vaccine-induced immune thrombotic thrombocytopenia) manifested as thrombosis simultaneously with a decrease in platelet count, a significant increase in D-dimer levels and a detection of factor 4 platelet (PF4) antibodies. We present a detailed review of the epidemiology, pathogenesis, clinical presentation, diagnostics and treatment of VITT, which is by its nature an immune complication, similar to the processes occurring in heparin-induced thrombocytopenia (HIT). All international and national organizations and regulatory authorities, including experts in the field of thrombosis and hemostasis and the VITT expert council recommend continuing the prompt mass vaccination against COVID-19 as the only method that can reduce the incidence of severe cases, stop the spread of COVID-19 infection and the emergence of new dangerous mutations in the viral genome. Failure to vaccinate poses an incomparably greater risk of fatal thrombotic and inflammatory complications associated with infections, compared with the risks of extremely rare adverse events that can occur after vaccination. It should be noted that information on VITT, described as a sporadic phenomenon of an abnormal immune response to some variants of vaccines against COVID-19, cannot be translated to other vaccines (including registered in the Russian Federation) and even more cannot be a reason for refusal to use them.</p></abstract><trans-abstract xml:lang="ru"><p>После запуска массовой вакцинации в Европе и Великобритании стали появляться сообщения о редких случаях тромбозов атипичных локализаций, включая тромбозы синусов головного мозга и висцеральных вен, связанных с применением аденовирусных векторных вакцин AstraZeneca (ChAdOx1) и Johnson &amp; Johnson/Janssen. Синдром, который получил название VITT (англ. vaccine induced immune thrombotic thrombocytopenia) – вакцин-индуцированная иммунная тромботическая тромбоцитопения, сопровождается снижением количества тромбоцитов, значительным повышением уровня Д-димера и выявлением антител к тромбоцитарному фактору 4 (англ. platelet factor 4, PF4). В статье представлен детальный обзор вопросов эпидемиологии, рассмотрены клинические симптомы, патогенез, методы диагностики и лечения VIТT, которая по своей природе является иммунным осложнением, подобным гепарин-индуцированной тромбоцитопении (ГИТ). В настоящее время все международные и национальные регуляторные организации, сообщества гематологов, включая специальную экспертную комиссию по VITT, рекомендуют продолжение скорейшей массовой вакцинации против СOVID-19 как единственного метода, который способен снизить частоту тяжелых случаев инфекции, остановить ее распространение и появление новых опасных мутаций в вирусном геноме. Отказ от вакцинации грозит несравнимо большим риском смертельных тромботических и воспалительных осложнений, связанных с инфекций, по сравнению с рисками крайне редких нежелательных явлений, которые могут возникнуть после вакцинации. Информация по VITT, описанной в качестве крайне редко возникающего феномена аномальной иммунной реакции на некоторые варианты вакцин против СOVID-19, не может транслироваться на другие вакцины (в частности, одобренные в Российской Федерации) и тем более не может быть причиной для отказа в их использовании.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вакцин-индуцированная тромботическая тромбоцитопения</kwd><kwd>VITT</kwd><kwd>тромбоз</kwd><kwd>коронавирус</kwd><kwd>SARS-CoV-2</kwd><kwd>СOVID-19</kwd><kwd>гепарин-индуцированная тромбоцитопения</kwd><kwd>ГИТ</kwd><kwd>вакцинация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vaccine-induced immune thrombotic thrombocytopenia</kwd><kwd>VITT</kwd><kwd>thrombosis</kwd><kwd>coronavirus</kwd><kwd>SARS-CoV-2</kwd><kwd>COVID-19</kwd><kwd>heparin-induced thrombocytopenia</kwd><kwd>HIT</kwd><kwd>vaccination</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Обзор выполнен при финансовой поддержке РФФИ в рамках научного проекта РФФИ №20-04-60274.</funding-statement><funding-statement xml:lang="en">The review was funded by RFBR, project number 20-04-60274.</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">WHO Coronavirus (COVID-19) Dashboard.
