Professor Robin Shattock and his team in Imperial College London’s Department of Infectious Disease developed a candidate vaccine within 14 days of getting the sequence from China. They have been testing the vaccine on animals since 10 February and plan to move to clinical trials in the summer. The self-amplifying RNA vaccine works by effectively injecting new genetic code into a muscle, instructing it to make a protein found on the surface of coronavirus, which triggers a protective immune response. Professor Robin Shattock told The Telegraph: "We have the kind of technology to be able to generate a vaccine with a speed that's never been realised before. Most vaccines are five years in the discovery phase, and at least one or two years to manufacture and get into trials."
