The country will narrowly miss President Biden's goal of having 70% of the U.S. adult population at least partially vaccinated by July 4, according to a White House official who did not want to get ahead of the public announcement. But the official also noted that 70% of those 30 and older have already been vaccinated a week and a half ahead of Independence Day and that those 27 and older are expected to also reach the 70% mark by July 4.
