Microsoft (MSFT) founder and philanthropic billionaire Bill Gates is spending “billions” of dollars on seven possible vaccines for the coronavirus and the disease it causes, COVID-19, in hopes of finding an end to the pandemic.

Through his philanthropic organization, the Bill & Melinda Gates Foundation, Gates revealed that he was funding several efforts in partnership with other companies and countries to “save months, because every month counts.”

“Our early money can accelerate things,” Gates told The Daily Show with Trevor Noah. “Of all the vaccine constructs, the seven most promising of those, even though we’ll end up picking at most two of them, we’re going to fund factories for all seven, and just so that we don’t waste time in serially saying, ‘Okay, which vaccine works?’ And then building the factory.”

Gates added that spending “a few billion dollars in this situation we’re in, where there’s trillions of dollars — that’s a thousand times more — trillions of dollars being lost economically, it is worth it.”

Asked about the remarks, Gates Foundation said in a statement to Yahoo Finance: “The Gates Foundation is working with a range of national and multilateral stakeholders who are funding the development of vaccines for COVID-19. Many of the current vaccine approaches are novel and have never been scaled for a commercialized product… The foundation is exploring using its catalytic funding to get the process moving, recognizing that any large-scale projects will require multilateral and/or government funding.”

‘The ultimate solution... is to create a vaccine’

There are more than 330,000 cases of the coronavirus infection in the U.S., surpassing the rest of the world, according to data compiled by Johns Hopkins as of Monday morning.

“This is a nightmare scenario, because human-to-human transmission of respiratory viruses can grow exponentially,” Gates told Fox News on Sunday. “And we had kept on going to work, traveling like we were.”

Gates noted that with the introduction of extreme social distancing and improved testing, both of which he called for previously, the situation could improve so that the overall death toll falls short of the 100,000-240,000 estimated by the White House.

“If we do the social distancing properly, we should be able to get out of this with the death number well short of that,” Gates said. “I do think we get the testing fixed, we get all 50 states involved, we’ll be below that. Of course we’ll pay a huge economic price in order to achieve that.”
