Russia's Sputnik V vaccine against Covid-19 is more than 90 per cent effective, a representative of the health ministry said on Monday, citing data collated from vaccinations of the public rather than from an ongoing trial.
The comments followed a statement earlier on Monday by vaccine developers Pfizer Inc and BioNTech, who said their experimental Covid-19 vaccine was more than 90 per cent effective.
"We are responsible for monitoring the effectiveness of the Sputnik V vaccine among citizens who have received it as part of the mass vaccination programme," Oksana Drapkina, director of a research institute under the health ministry, said in a statement.
"Based on our observations, it is also more than 90 per cent. The appearance of another effective vaccine - this is good news for everyone," Drapkina said.
