UK could become first country in world to deliberately infect volunteers with Covid-19 for vaccine test

The UK could host the world's first Covid-19 'human challenge trials' in which healthy volunteers are infected with coronavirus to test the effectiveness of experimental vaccines. The studies are expected to begin in January at a secure quarantine facility in east London, according to a Financial Times report. Those taking part will be inoculated with a vaccine before receiving a “challenge” dose of Sars-Cov-2, the virus that causes Covid-19, under controlled conditions a month or so later.
