Russian President Vladimir Putin said on Wednesday that he has taken an experimental nasal vaccine against the coronavirus, three days after he received his booster shot, as Russia faces its worst surge of infections and deaths since the pandemic began.

Putin was vaccinated with Sputnik V, Russia’s domestically developed Covid-19 vaccine, in the spring.
