More than 30m of UK government money is to fund the world's first Covid-19 challenge trials", in which healthy young volunteers are intentionally infected with the virus to hasten the development of a vaccine.

The trials have the potential to yield results more quickly than conventional vaccine field trials in which researchers must wait for participants to get infected in the real world.
