More than half of American adults vaccinated as COVID-19 cases ebb

WASHINGTON - More than half of all adults in the United States have been fully vaccinated against COVID-19, the White House said on Tuesday, roughly six weeks before U.S. President Joe Biden's July 4 goal of 70% of the adult population receiving at least one shot.

The halfway mark comes as federal, state and local leaders press ahead with delivering COVID-19 shots to people who have not yet received them, while also battling vaccine hesitancy, fears and misinformation. "Now, with another week left in May, half of all U.S. adults are fully vaccinated," White House senior COVID-19 adviser Andy Slavitt tweeted overnight.
