Russia's Sputnik V coronavirus vaccine is 95% effective, its developers said Tuesday as Russian Federation seeks a leading role in the high-stakes global race for a safe, effective vaccine that can end to the deadly pandemic.

"It has shown a 91.4 per cent efficacy on day 28 after the first dose while preliminary data from volunteers obtained 42 days after the first dose (corresponds with 21 days after the second dose) indicates an efficacy of the vaccine above 95 per cent", stated press statement issued by RDIF.

Pfizer-BioNTech and Moderna vaccines have shown better efficacy at 95 percent, while AstraZeneca-University of Oxford vaccine had shown 70.4 percent efficacy.

Some volunteers had short-term minor adverse effects such as pain at the injection site and flu-like symptoms including fever, weakness, fatigue, and headaches, it said.

As per Russian scientists, the Sputnik V vaccine is based on a well-studied human adenoviral vector platform that has proven safe and effective with no long-term side effects in more than 250 clinical trials globally conducted during the past two decades - while the history of the use of human adenoviruses in vaccine development began in 1953. "The drug's final efficacy assessment will be made available after Phase III clinical trials are concluded", Gintsburg added.

Russian Federation plans to start mass vaccination against the coronavirus in 2021, Deputy Prime Minister Tatyana Golikova, who is overseeing Russia's Covid-19 response, said earlier Tuesday.

The Sputnik vaccine, named after the Soviet-era satellite that triggered the space race in a nod to the project's geopolitical importance for Moscow, is administered in two shots, each of which will cost less than US$10, according to the official Sputnik V Twitter account.

RDIF's worldwide manufacturing partners are expected to produce the vaccine for more than half a billion people in 2021.

Russia's two-shot Sputnik V COVID-19 vaccine will cost less than $20 per person on global markets and will be free of charge for Russian citizens, according to a statement on the official Sputnik V Twitter account.

It can be stored at between two and eight degrees Celsius (between 35.6 and 46.4 degrees Fahrenheit), they said, instead of the temperatures below freezing required for some other vaccines.
