Sputnik V is the Russian vaccine. The vaccine was developed by the Moscow-based Gamaleya Institute, using funding from the Russian Direct Investment Fund (RDIF)
Sputnik V uses human adenovirus vectors, whereas Oxford-AstraZeneca’s vaccine uses chimpanzee adenovirus vectors. Sputnik V is a so-called viral vector vaccine. Vectors are vehicles, which can induce a genetic material from another virus into a cell..
Russian scientists came up with a breakthrough idea to use two different types of adenovirus vectors (rAd26 and rAd5), that normally cause the common cold, for the first and second vaccination, boosting the effect of the vaccine.
Sputnik V is delivered in two shots, administered 21 days apart and in liquid form. It must be stored at minus 18 degrees Celsius (minus 0.4 degrees Fahrenheit) or below. The vaccine will be free and voluntary for Russian citizens. Others will pay about $26 for the two doses.
As of December 2020, requests for more than 1.2 billion doses of the Sputnik V vaccine have come from more than 50 countries.
