The Biden administration is set to announce Wednesday that it's buying another $1 billion of rapid at-home tests, on top of the $2 billion investment in September.
White House COVID-19 response coordinator Jeff Zients is expected to make the announcement at the afternoon COVID-19 briefing.
With this new purchase, combined with September's investment and the FDA approval of the ACON rapid test money, the White House says the U.S. is now on track to quadruple the number of rapid at-home tests available to Americans in December.
A White House official emphasized that this is not just about more tests on the market, but more affordable tests on the market.
