Oxford COVID vaccine success - and then there were three

There is a team of scientists at the University of Oxford that is both over-joyed and shattered. <br /><br />Trials of their vaccine with AstraZeneca in the fight against coronavirus indicate it is up to 90% effective. <br /><br />There is also some suggestion that the vaccine could even help to prevent the spread of COVID-19. <br /><br />On the Sky News Daily podcast with Dermot Murnaghan we hear from Professor Sarah Gilbert, who is the woman who led the Oxford team, while our science correspondent Thomas Moore examines the detail as we compare the Oxford vaccine with the Pfizer/BioNTech and Moderna ones.<br /><br />Plus, why medical student Lois Clay-Baker signed up to the trials - that aim to help life for the likes of Gerry and Ann Wells, in their 70s, get back to some kind of normal.<br /><br />Daily podcast team:<br />Podcast producer - Annie Joyce<br />Podcast producer - Nicola Eyers<br />Podcast producer – Emma-Rae Woodhouse <br />Interviews producer - Oli Foster<br />Archive - Simon Windsor<br />Music - Steven Wheeler
