It was the news the world had been waiting for. A major breakthrough in the race to find a vaccine in the fight against coronavirus. In a week when the UK surpassed 50,000 COVID-related deaths in this pandemic, Monday’s announcement offered optimism – albeit tinged with some caution. While the American pharmaceutical giant Pfizer financed the vaccine, the science itself is the work of German company BioNTech – founded by husband and wife team, physicians Ugur Sahin and Ozlem Tureci.We hear from Dr Sahin on this edition of the Sky News Daily podcast hosted by Dominic Waghorn. We are also joined by Dr Charlie Weller, who is head of vaccines at the Wellcome Trust research charity, and GP Dr Ellie Cannon as we examine what more we know about the vaccine, the preparations for distribution if approved and the challenges that still remain.Daily podcast team:Podcast producer - Annie JoycePodcast producer - Nicola EyersPodcast producer – Emma-Rae Woodhouse Interviews producer - Oli FosterArchive - Simon WindsorMusic - Steven Wheeler
