US reaches 75% of sdults with at least one vaccine dose

Three-quarters of U.S. adults have received at least one dose of a Covid-19 vaccine as of Tuesday, according to the White House, setting a new milestone in the country’s fight against the pandemic.

But with a continued surge of cases, hospitalizations and deaths due to the delta variant of the coronavirus, President Joe Biden plans a speech Thursday to outline a "six-pronged strategy” to "get the pandemic under control,” Press Secretary Jen Psaki said. The U.S. hit 70% of adults with at least one dose in early August, four weeks after Biden’s July 4th target for the achievement. Despite wide availabiltiy of free shots, hesitancy among many Americans -- especially political conservatives -- has left the U.S. well behind many other countries in inoculating its population.
