WASHINGTON (AP) For much of the past two years, America has been first in line for COVID-19 vaccines and treatments. Now, as drugmakers develop the next generation of therapies, the White House is warning that if Congress doesnt act urgently the U.S. will have to take a number.

Already the congressional stalemate over virus funding has forced the federal government to curtail free treatment for the uninsured and to ration monoclonal antibody supplies. And Biden administration officials are expressing increasing alarm that the U.S. is also losing out on critical opportunities to secure booster doses and new antiviral pills that could help the country maintain its reemerging sense of normalcy, even in the face of potential new variants and case spikes.

Japan, Vietnam, the Philippines, and Hong Kong have all placed orders for treatments and vaccine doses that the U.S. cant yet commit to, according to the White House.

Months ago, the White House began warning that the country had spent through the money in the $1.9 trillion American Rescue Plan that was dedicated directly to COVID-19 response. It requested an additional $22.5 billion for what it called urgent needs in both the U.S. and abroad.

The Senate last month closed in on smaller $10 billion package focused on domestic needs. But even that deal fell apart as lawmakers objected to an announcement from the Centers for Disease Control and Prevention that it would end Trump-era border restrictions related to the pandemic.

The White House this week is mounting a push for doctors to get less stingy about prescribing the antiviral pill Paxlovid, which was initially rationed for those at the highest risk for severe outcomes from COVID-19 but is now more widely available. A 20 million-dose order placed last year by the government helped boost manufacturing capacity.
