Russia's Sputnik COVID-19 vaccine to cost less than $20 per person internationally

The Sputnik vaccine is administered in two shots, each of which will cost less than $10 each, according to the official Sputnik V Twitter account. For Russian citizens, vaccination will be free of charge.

The pricing announcement comes as Russia looks to scale up distribution and production. Kirill Dmitriev, head of Russia's RDIF sovereign wealth fund, said Moscow and its foreign partners had capacity to make more than a billion doses starting from next year, enough to vaccinate over 500 million people.

The international market price for Sputnik V unveiled on Tuesday is cheaper than some other Western rivals such as a vaccine produced by Pfizer-BioNTech, which costs 15.5 euros per shot, but more expensive that a vaccine produced by AstraZeneca which will be sold in Europe for around 2.5 euros per shot.

Dmitriev told Reuters that Moscow had deliberately tried to get the price down to make it available to as many people around the world as possible.

RDIF said in a statement: "Sputnik V will be two or more times cheaper than mRNA vaccines with similar efficacy levels."

It said it was basing its assessment on mRNA vaccines where pricing had already been announced and interim phase three clinical trials were underway.

RDIF and the Gamaleya National Center said earlier on Tuesday that new clinical trial data based on 39 confirmed cases and 18,794 patients who got both shots had shown that Sputnik V was 91.4% effective on day 28 and over 95% effective on day 42.

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 vaccine.
