Russia’s Sputnik V coronavirus vaccine is 95 percent effective according to a second interim analysis of clinical trial data, its developers said on Tuesday.
The calculations were based on preliminary data obtained 42 days after the first dose, Russia’s health ministry, the state-run Gamaleya research centre and the Russian Direct Investment Fund (RDIF) said in a statement.
They did not note the number of cases used to make the calculation, however.
The two-shot Sputnik V vaccine will cost less than $20 per person on international markets and will be free of charge for Russian citizens, according to a statement on the official Sputnik V Twitter account.
The head of Russia’s sovereign wealth fund Kirill Dmitriev said earlier on Tuesday that the vaccine would be priced significantly lower than other rivals with similar efficacy levels. Mr Dmitriev added Moscow aims to produce more than 1 billion doses at home and abroad next year.
Moscow has been criticised by some scientists in the West who have accused it of cutting corners in an effort to try to rush out the Sputnik V vaccine.
Russia has denied that, alleging a Western dirty tricks campaign to put people off its vaccine in what it believes has become a battle for legitimacy and market share.
