Hopes are growing that a dark-horse coronavirus vaccine from a tiny U.S. drugmaker can shore up supplies in the U.S. and globally as safety concerns and production problems shadow shots from Johnson & Johnson and AstraZeneca, Politico reported.

The shot entered late-stage clinical trials months after candidates from bigger names like Pfizer and Moderna.
