According to data from the Gamalei Institute in Moscow, which developed the Sputnik-V vaccine, the effectiveness of Sputnik-Light (which is the first dose of Sputnik-V) against the Delta variant reaches 70% over a period of three months. after vaccination.

In the age group up to 60 years, the effectiveness of the vaccine exceeded 75%.
