Reps. Carlos Curbelo, Will Hurd, Jeff Denham and David Valadao filed a petition on Wednesday that could force a vote to make DACA law, permanently protecting from deportation undocumented immigrants who came to the U.S. as children.

What's next: The petition must first get 218 signatures, which means 20 Republicans must support the move as well as all House Democrats. At least 15 Republicans are on board, Politico reports.

It'll likely be a long time before children are vaccinated against COVID-19, even though vaccinating kids could eventually play an integral role in reducing the virus' spread.

The big picture: None of the leading contenders in the U.S. are being tested for their effectiveness in children. Even once one of them gains authorization from the Food and Drug Administration, there will only be a limited number of available doses.
