The administration of President Joseph Biden announced March 17 a $10 billion allocation of funds for testing to reopen schools in the final months of the current school year, a source of revenues that was provided by the recently passed $1.9 trillion American Rescue Plan. The news follows by one day a new FDA policy on screening tests that allows test developers to distribute tests designed to screen those who are asymptomatic without first validating the test for this use, although there are still questions as to whether this new push will yet again crimp vital testing supplies.
