Sputnik V vaccine is 91.6% effective against symptomatic covid-19

Of the 14,964 people who received the vaccine, 16 developed symptomatic covid-19 compared with 62 out of 4902 in the placebo group. The results, published today in The Lancet, suggest efficacy was similar across all age groups, including among people over the age of 60.

“All our critics are sitting quiet at the moment,” Dmitriev said during a press conference on 2 February. “We have addressed all of the concerns […] Sputnik V has proven itself to be one of the most effective and safest vaccines of the world.” Sputnik V has already been approved in 15 countries, and this could increase to 25 countries by the end of this week, he said.
