Half of all adults in the United States are expected to have been fully vaccinated against COVID-19 this week, it was announced at a briefing of the White House COVID-19 Response Team. The Centers for Disease Control and Prevention says almost 130 million U.S. adults are now fully vaccinated — or about 49.8% of the adult population. Earlier this month, President Joe Biden announced a goal of 70% of Americans having at least one dose by July 4.

CDC data shows that at least 25 states and Washington, D.C., have fully vaccinated at least half of their adult residents. Early on Tuesday, Moderna announced that its vaccine is safe and effective in children between the ages of 12 and 17. If approved by regulators next month, it would be the second coronavirus vaccine available in the United States to children.
