Russia registered 21,378 COVID-19 cases over the past 24 hours, down from 22,160 the day before, taking the overall tally to 6,491,288, the federal response centre said on Tuesday.
South Korea has reported 826 new cases of the coronavirus, its biggest daily jump in about six months, as fears grow about another huge wave of the virus in the greater capital area.
Although Russia was among the first countries to announce and deploy a coronavirus vaccine, only about 14% of the population has received at least one shot.
