Sputnik V shot around 90% effective against Delta, claim developers

Russia’s Sputnik V vaccine against Covid-19 is around 90% effective against the highly contagious Delta variant of coronavirus, its developers said on Tuesday. The shot, which Russia has actively marketed abroad, was previously found by researchers to be almost 92% effective against the original strain of coronavirus. Denis Logunov, deputy director of Moscow’s Gamaleya Institute which developed Sputnik V, said the Delta variant efficacy figure was calculated based on digital medical and vaccine records, the RIA news agency reported.

Russian authorities have blamed a recent surge in Covid-19 cases in the country on the infectious Delta variant, which they say accounts for around 90% of all new cases, and on the reluctance of many Russians to get vaccinated. Reuters
