Да, ты прав, мой прокол, они только согласовали это в декабре и огласили, что к концу февраля начнут тестирование. Ведутся ли тесты или нет - ещё не известно. https://en.wikipedia.org/wiki/Sputnik_V_COVID-19_vaccine#cite_note-33
"On 21 December 2020 the Russian Direct Investment Fund (RDIF), the Gamaleya National Center, AstraZeneca and R-Pharm have signed an agreement aimed at the development and implementation of a clinical research program to assess the immunogenicity and safety of the combined use of one of the components of the Sputnik V vaccine developed by the Gamaleya Center, and one of the components of the AZD1222 vaccine, developed by AstraZeneca and the University of Oxford.[32] The study program will last 6 months in several countries, and it is planned to involve 100 volunteers in each study program. On 9 February 2021, the Ministry of Health of the Republic of Azerbaijan allowed clinical studies in the country for the combined use of the Sputnik V vaccine and the vaccine developed by AstraZeneca, stating that the trials would begin before the end of February 2021.[33][34]"
