According to the CDC, 46% of Texans have been fully vaccinated.
The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.
More than 620,000 Americans have died from COVID-19 and over 4.3 million people have died worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
Just 59.1% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.
New Americans are getting vaccinated at the highest rate in over two months, White House COVID-19 data director Cyrus Shahpar tweeted.
There are currently 166,524,108 Americans ages 12 and up who are fully vaccinated, according to the CDC.
More than 8,300 Americans are currently being admitted to hospitals each day for COVID-19.
The COVID19 Forecast Hub at U Mass Amherst, used by the CDC, predicts that hospital admissions could skyrocket to as high as 33,300 per day by Sept. 4.
Even the lowest end of the forecast -- 9,600 hospital admissions per day -- is much higher than where we are now.

The Dallas Independent School District, the second largest in Texas, said it's temporarily requiring face masks for all students, staff and visitors as of Tuesday.
It's not clear how long the mask mandate will last.
In the Austin Independent School District, students, staff and visitors must wear face masks beginning Wednesday.
This comes after Texas Gov. Greg Abbott imposed a ban on mask mandates.
In Houston, Texas' biggest school district, the board of education will vote this week on a proposed mask requirement, according to ABC Dallas affiliate WFAA.
Dr. Richard Besser, president and CEO of the Robert Wood Johnson Foundation and former acting director of the CDC, said parents should not get to choose if their kids wear masks in school.
"Allowing it to be an issue of personal choice is fine if it only affected your child, but it doesn't. It affects everyone around your child as well," Besser told "Good Morning America" Tuesday.
"There's a lot we don't know about this virus," Besser said. "I urge parents, I urge schools, I urge governors, not to underestimate what we're dealing with."
