Putin announced getting the jab, which was kept out of the public eye, at a session of the Russian Geographical Society, in which he took part via video link.

"Right now, before entering this hall, I have also gotten the second jab. I hope everything will be fine. I don't even hope as much as I'm sure of it," the Russian leader said.

The president told reporters after the event that he did not experience any adverse effects after the second jab.

"As you see, everything is normal, no side effects," Putin said, adding that doctors told him he developed "a good immune response" after the first dose.

He got his first coronavirus vaccine jab on March 23, also out of sight of the cameras, and the Kremlin would not reveal which of the three vaccines currently approved for use in Russia the president has taken.

His vaccination comes several months after widespread immunisation against COVID-19 started in Russia - a delay that puzzled many, with some critics arguing that it was contributing to the already existing public hesitancy about the vaccine.

Russian authorities have given regulatory approval to three domestically developed vaccines - Sputnik V, EpiVacCorona and CoviVac.
