Vaccination rate nearly double than it was in mid-July
The U.S. vaccination rate per day is now nearly double than it was in mid-July, according to the White House.
"Back in mid-July we were averaging 500,000 vaccinations per day. Today, we’re averaging 900,000," White House COVID response coordinator Jeff Zients told reporters Tuesday. "Last week we got over 6 million shots, the biggest weekly total since July 5."

The increase in vaccinations comes amid fear about the rapidly spreading delta variant.
The delta variant, which is more transmissible, has also been part of the conversation around booster shots of the mRNA and J&J vaccines. The Biden administration said Americans would need a third shot eight months after their second because of waning immunity.
The Biden administration is standing by its decision to call for vaccine boosters beginning Sept. 20 despite questions about whether there's enough data and the unusual process of announcing a plan before the FDA has evaluated the data and made a recommendation.
