The drug previously showed over 95% efficacy, with the latter uplifting results shown 42 days after the first shot. The evaluation was carried out among 18,794 volunteers. Twenty-eight days after receiving the first dose (and 7 days after the second dose) of the vaccine or placebo, showing a 91.4% efficacy rate for the Sputnik V vaccine.

According to scientists, it is expected to grant immunity for at least two years.
