Just hours after the UK approved Pfizer's coronavirus vaccine and announced immediate plans for vaccination, Russian President Vladimir Putin on Wednesday ordered a "large-scale vaccination" campaign using the Russian jab which was rushed out this summer.
Russia's Sputnik V in August became the world's first Covid-19 vaccine to be approved after Putin revealed that his own daughter was inoculated.
The interim analysis of clinical trial data has shown that the Sputnik V jab was 95 per cent effective 42 days after the first dose was administered on par with two other leading vaccines.
Sputnik V's developers, however, have yet to release full clinical data of their Phase III trials.
