There's an innovative, but risky way we could speed up development of a COVID-19 vaccine. Some scientists argue we should intentionally infect volunteers with the coronavirus to get a vaccine sooner.

Tradeoffs' Dan Gorenstein explores how scientists could ethically and safely infect people to speed up the fight against COVID-19.
