The UK could be the first country in the world to carry out Covid "challenge trials" - where healthy volunteers are deliberately infected with coronavirus to test possible vaccines.

It is understood the studies - first reported by the Financial Times - would be conducted in London.

The UK government said it was holding discussions about developing a vaccine through such "human challenge studies".

No contracts have yet been signed, the BBC understands.

'Out of the pandemic'

Alastair Fraser-Urquhart, an 18-year old university student, is planning on volunteering for the trial if it is given the green light to go ahead. He helps run the advocacy group, 1Day Sooner.
