Bill Gates is plugging money into building factories for seven promising coronavirus vaccines, despite the fact it will mean wasting billions of dollars.

In a preview clip released from Friday’s episode of The Daily Show, the Microsoft billionaire told host Trevor Noah that his philanthropic organization, the Gates Foundation, can mobilize faster than governments to fight the coronavirus outbreak.

“Because our foundation has such deep expertise in infectious diseases, we’ve thought about the epidemic, we did fund some things to be more prepared like a vaccine effort, our early money can accelerate things,” said Gates.

Gates said he was picking the top seven vaccine candidates and building manufacturing capacity for them. “Even though we’ll end up picking at most two of them, we’re going to fund factories for all seven, just so that we don’t waste time in serially saying, ‘OK, which vaccine works?’ and then building the factory,” he said.
