That is a very good question. We need to be cautious on the timings for the development of a vaccine, but I am pushing it as hard as possible. It is true that the science has developed in the last 10 days—scientists working around the world to understand the virus have made some progress—and I was convinced enough to put £20 million into that global effort; and we may well put more in. I was impressed by the science, as reported to me by the chief medical officer, so my assessment is now slightly more promising than when the hon. Lady last asked me this question.
