Everyone wants a coronavirus vaccine as soon as possible - but what is involved, and how long will it take? On the panel for this week’s episode are New Scientist journalists Rowan Hooper, Penny Sarchet, Jacob Aron and Clare Wilson. The team is joined by Katrina Pollock, a vaccine scientist from Imperial College London, who explains the work that needs to be done before we have a safe and effective vaccine for covid-19.

We also hear how to treat human organs outside of the body, in an effort to make the organs healthier when transplanted into patients in need.
