(Updates with Putin comments)
MOSCOW, Nov 24 (Reuters) - Russia announced progress in its Sputnik suite of COVID-19 vaccines on Wednesday, with a new version aimed at children and a nasal spray that President Vladimir Putin said he had taken as a booster.
Putin said in televised comments that he had been re-inoculated six months after his initial dose of the Sputnik V vaccine because his antibody levels had dropped.
He said the booster took the form of an injection, followed the next day by a powder sprayed into both nostrils.
"That was all - I didn't feel anything. Nothing. Today, after these two procedures, I already did some sport in the morning," he said.
Russia was quick to develop its Sputnik V shot last year, but the Kremlin has blamed a recent surge in cases on widespread public reluctance to get vaccinated. October was the deadliest month of the pandemic so far in Russia.
Many people are hesitant to take the jab and distrustful of official assurances about its safety - an attitude that Putin has tried to counter by talking about his own experience of it.
Deputy Prime Minister Tatiana Golikova announced separately that the health ministry would register a new Sputnik M vaccine for use for children aged 12-17 later on Wednesday, with shots expected to be available at the end of December.
