Reuters: “Russian President Vladimir Putin has been revaccinated against COVID-19, Russian news agencies quoted him as saying on Sunday. Putin said in June 2021 that he had been vaccinated with Sputnik V vaccine.
“‘Today, on your recommendation and that of your colleagues, I got another vaccination, Sputnik Light. This is called revaccination,’ Putin said at a meeting with the deputy director of the Gamaleya Research Centre for Epidemiology and Microbiology, which developed both vaccines.”
