According to the makers of Russia's flagship COVID-19 vaccine Sputnik V, phase 3 trials showed efficacy rates of "above 95 percent". 

The List

  • The Gemaleya Institute said the figure was based on preliminary results from tests on volunteers 42 days after the first injection of the vaccine. 
  • Russian officials say the Sputnik V vaccine has greater efficacy than the Oxford-AstraZeneca vaccine, which is on average 70% efficient.
  • Pfizer-BioNTech and Moderna claim their vaccines are around 95% effective.
  • Referring to the Pfizer-BioNtech vaccine, the Gemaleya Institute said that Sputnik is “cheaper than mRNA vaccines with similar efficacy levels,”.
  • Oxford-AstraZeneca and Sputnik V vaccines can be kept in standard fridges, while the Pfizer-BioNTech vaccine requires more expensive subzero conditions.
