The U.K. government announced Tuesday it is investing 33.6 million pounds (about $43.5 million) in the first stage of what are known as "challenge trials." The groundbreaking but controversial studies involve volunteers being injected with a potential vaccine before being given a dose of COVID-19.

The trials could start in January of next year if they get regulatory and ethical approval first, the U.K. government said in a statement.

While young people rarely die of the disease, there is increasing evidence they can be left with long-term debilitating illnesses.
