Unlike most other COVID-19 vaccines, which are given as two shots of the same product, the Russian Sputnik V vaccine relies on two doses delivered using different inactive viruses, known as vectors. The Gamaleya Institute that developed the vaccine says it is more than 91% effective after the two-dose course. We apologize, but this video has failed to load.
