Researchers have said a Russian trial testing the effectiveness of revaccination with the Sputnik V shot to protect against new mutations of the coronavirus is producing strong results, Reuters reports.
“[A] recent study carried out by the Gamaleya Centre in Russia showed that revaccination with Sputnik V vaccine is working very well against new coronavirus mutations, including the UK and South African strains of coronavirus,” said Denis Logunov, a deputy director of the centre, which developed the Sputnik V shot.
