Nearly 9 million Americans had been given their first Covid-19 vaccination dose as of Jan. 11, the U.S. Centers for Disease Control and Prevention said, as states scrambled to step up inoculations that have yet to slow the roaring pandemic.

The United States recorded more than 1 million new Covid-19 cases in the past week as new infections rose in every state except for Hawaii, according to a Reuters analysis of state and county reports.

White House Coronavirus Task Force Coordinator Dr. Deborah Birx dismissed the notion that the White House was considering a strategy of allowing Americans to become infected with coronavirus in order to reach “herd immunity.”
