Biden, Harris urge vaccinations as U.S. looks likely to miss July 4 target

The United States has administered 300 million COVID-19 vaccinations in 150 days, a White House official said on Friday ahead of Biden's speech.

Biden said the new Delta virus variant, first detected in India, was "a serious concern" which underscored the need to keep increasing vaccination rates.
