According to a Kremlin spokesman, the President of the Russian Federation has a high level of antibodies to coronavirus.
He just got a booster shot, and he also took part in a nasal vaccine experiment. Therefore, I hope this is a sufficient level of protection. Dmitry Peskov
Recall that on November 24, 2021, Putin openly stated that he had been vaccinated with a nasal vaccine against COVID-19. It happened literally the next day after the re-vaccination. At the same time, his press secretary Dmitry Peskov said that he did not plan to take part in the trials of a nasal vaccine.
