Joe Biden laid out a lofty goal to vaccinate 70% of American adults against COVID-19 by Independence Day, saying the U.S. would need to overcome “doubters” and laziness to do it. “This is your choice,” he told Amercians. “It’s life and death.”As for the ambition of his 70% goal, Biden added: “I’d like to get it at 100%, but I think realistically we can get to that place between now and July Fourth.”He won’t.With the July Fourth holiday approaching, the White House acknowledged this week that Biden will fall shy of his 70% goal and an associated aim of fully vaccinating 165 million adults in the same time frame.
