The first federally approved coronavirus vaccine was set to arrive at 145 locations across all 50 states Monday, a landmark moment as the nation struggles to contain a virus that's killed 300,000 Americans.
The vaccine, developed by German company BioNTech and its United States partner Pfizer, was given emergency use authorization by the Food and Drug Administration on Friday night.
Trucks departed Pfizer's plant in Portage, Michigan, on Sunday and the company expects to deliver 2.9 million doses to 636 locations by the end of this week.
Still, the vaccine will not be given to the vast majority of Americans until well into next year. And it will take some time to make even a dent in a pandemic that is killing thousands of people across the U.S. every day — more than ever before.
