A Covid-19 vaccine claims to be 90% effective. It uses genetic material, messenger RNA. Daniel Anderson of Harvard MIT Health Science tells us about the huge potential of mRNA to provide treatments for many medical conditions.

However, rolling out such a vaccine globally faces a huge range of economic and practical obstacles as ethicist Nicole Hassoun of Binghamton University explains.

And a unique experiment shows despite a vast range of precautions including being isolated US Marines have contracted Covid -19. Stuart Sealfon, Professor of Neurology at Mount Sinai Hospitals says this study shows we need testing to be integrated more thoroughly into everyday life and that many of the precautions we currently use may not be enough to prevent transmission.

We all feel pain on a regular basis; when we stub a toe, break a bone or even experience heartbreak. Bebeto from Cameroon wants to know how to cope with a pain in his wrist that just won’t go away. Does a positive mindset help? Or perhaps meditation? Marnie Chesterton speaks to psychologists and neuroscientists to find the answers.

We hear from two people with very different experiences of pain. Lucy has fibromyalgia and experiences pain all over her body every day. While Stephen has a rare genetic condition which means he doesn’t feel physical pain at all. But they both argue that pain shouldn’t always be unwanted.
