Russia’s Sputnik V vaccine has 92% efficacy in trial
Russia’s Sputnik V coronavirus vaccine gives around 92% protection against Covid-19, late stage trial results published in The Lancet reveal. It has also been deemed to be safe – and offer complete protection against hospitalisation and death. The vaccine was initially met with some controversy after being rolled out before the final trial data had been released. But scientists said its benefit has now been demonstrated. It joins the ranks of proven vaccines alongside Pfizer, Oxford/AstraZeneca, Moderna and Janssen.
