Delta Variant Linked to COVID Surges Amid Slow U.S. Vaccination Rates as Global Inequity Persists

The White House says it will miss its goal of getting 70% of adults at least partially vaccinated by July 4. Vaccinations are available for anyone age 12 and up in the U.S., but just 45% of people in the U.S. are fully vaccinated, and only 16 states have fully vaccinated more than half of their populations.

Epidemiologist Dr. Ali Khan says despite more than 150 million people in the U.S. now being vaccinated against the coronavirus, the highly contagious Delta variant is quickly becoming a concern. "Our expectation should be, by July, this will be the dominant variant," he says.
