In view of the rapidly increasing number of new corona infections, significantly more people in the USA have recently been vaccinated again.
The vaccination campaign had stalled since June, with only around half a million injections being administered each day.
However, the trend is now reversing in view of the new corona wave, which is attributed to the particularly contagious delta variant.
816,000 vaccinations were given on Sunday, including 517,000 primary vaccinations, a senior White House official wrote on Twitter.
The latest data showed a "steady increase," said Cyrus Shahpar.
Number of vaccinations increased significantly
According to the official, the vaccination numbers in the past few days were well above those of the previous week.
On Saturday, for example, there were 712,000 cans, an increase of 77 percent compared to the previous week (403,000).
On Friday there was an increase of 43 percent.
In April, a good three million doses had been administered daily.
The number of new infections registered per day on a weekly average, which temporarily fell to 11,000 in June, is now back to 72,000.
The number of new infections is increasing across the country.
States with lower vaccination rates, including Louisiana and Florida, are particularly affected.
In the USA, almost 50 percent of the population of around 330 million people have so far been fully vaccinated, around 58 percent have received at least the first injection - less than in Germany, for example.
Initially missed target in adults
President Joe Biden had set the goal in the spring that by the national holiday on July 4th, 70 percent of adults should have received at least the first vaccination.
The target was missed despite ample supplies and vaccination incentives, it was only 67 percent.
Well, about a month later, it should soon be ready: The latest increase caused the rate among adults to rise to 69.9 percent by Sunday.
