The United States on June 14 crossed the grim milestone of 600,000 Covid-19 deaths, according to a Reuters tally, as slowing vaccination rates threaten the Biden administration target of having 70 percent of U.S. adults receive at least one shot and 160 million fully inoculated by July 4.

From free beer to free childcare, President Joe Biden on June 2 touted new efforts to get 70 percent of U.S. adults at least one shot of vaccination against Covid-19 by the July 4 Independence Day holiday.

President Joe Biden on May 4 announced a goal to vaccinate 70 percent of U.S. adults with at least one Covid-19 shot by the July 4 Independence Day holiday and said the government would innoculate 12- to 15-year-olds as soon as allowed. The president had previously announced July 4 as a target date for Americans to gather in small groups to celebrate the holiday and signal a return to greater normalcy in the middle of the pandemic.

Rising coronavirus cases in 39 U.S. states cast a shadow over the nation’s Fourth of July celebrations as health experts worried that holiday parties will cause a further spike in infections that could overwhelm hospitals.
