Yet more good news on the vaccine front, but this time from a surprising source.

Russia’s Sputnik V jab has been found to be 91.6 per cent effective, according to peer-reviewed data from late stage clinical trials published in The Lancet. The two-shot vaccine provides complete protection against moderate and severe cases of Covid-19. It is also safe, with no serious adverse reactions observed in trial participants.

Professor Ian Jones of the University of Reading and Professor Polly Roy of the London School of Hygiene and Tropical Medicine penned a comment published alongside the Lancet paper: “The development of the Sputnik V vaccine has been criticised for unseemly haste, corner cutting, and an absence of transparency. But the outcome reported here is clear and the scientific principle of vaccination is demonstrated, which means another vaccine can now join the fight to reduce the incidence of Covid-19.”
