70% Of U.S. Adults Will Have 1 Dose By End Of May

The U.S. is on pace to hit President Biden's goal of at least one dose of vaccine for 70% of U.S. adults by July 4. One model says that could happen by the end of this month. More than 108 million people are fully vaccinated, but there's concern about a drop in demand with people who are hesitant still holding out.
