Sputnik passed trials at least not less than all other leading vaccines. Now full interim Phase 3 trial results was published in The Lancet.
"(CNN)After criticism last year for an early rollout, Russia's
Sputnik V vaccine is 91.6% effective against
symptomatic Covid-19 and 100% effective against severe and moderate disease, according to an interim analysis of the vaccine's Phase 3 trial results.
The preliminary findings were published in The Lancet on Tuesday and are based on data gathered from 19,866 participants, of which around three-quarters (14,964) received two doses of the vaccine and a quarter (4,902) were given a placebo.
Sixteen cases of symptomatic Covid-19 were confirmed in the vaccine group 21 days after participants received the first vaccine dose. Sixty two cases were found in the placebo group -- equating to an efficacy of 91.6%.
The trial included 2,144 people over the age of 60 and a sub-analysis conducted on this group revealed the vaccine was well tolerated and had a similar efficacy of 91.8%.
The team also analyzed the efficacy of the vaccine against severe and moderate Covid-19 disease and 21 days after the first dose no severe or moderate cases were reported in the vaccinated group, while 20 were reported in the placebo group."
