Ten vaccines are in the final phase of trials. Health Secretary Matt Hancock has not ruled out securing a vaccine by Christmas, yet scientists say we might have to wait until 2022 - and according to Donald Trump, it was ready last month. Dates are repeatedly being thrown around - but with none yet approved and 7.5 billion people to immunise around the world, it begs the question, how long will it take for a vaccine to get our lives back to normal? In this episode of the Sky News Daily podcast, host Noel Phillips is joined by Professor Beate Kampmann, director of the Vaccine Centre at the London School of Hygiene and Tropical Medicine, to explain why she thinks COVID trials could be moving too quickly and Professor Bruce Y Lee, from City University, New York, to talk through how vaccinating the population may take longer than many have bargained for. Plus Jack Sommers, volunteer at the Oxford vaccine trials, shares his experienceCredits:Daily podcast team:Podcast producer - Annie JoycePodcast producer - Nicola EyersPodcast producer - Emma WoodhouseInterviews producers - Oli FosterArchive - Simon WindsorArchive - Rob FellowesMusic - Steven Wheeler
