Russian President Vladimir Putin has tested an experimental Covid-19 nasal vaccine that is not yet in clinical trial phase, his fourth vaccination in total, he said Wednesday.
Putin also received a Russian-made Sputnik Light booster on Sunday, six months after his second dose of Sputnik V.
After receiving the booster shot, Putin volunteered to take part in testing the intranasal vaccine in development by the Gamaleya Center, the maker of Sputnik V and the subsequent single dose Sputnik Light, he said at a televised meeting with government members.
