'Steady increase' in vaccines in past month, White House says
The U.S. saw its largest single-day increase in nearly nine months Friday.
The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.
More than 613,000 Americans have died from COVID-19 and over 4.2 million people have died worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
Just 57.9% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.
The CDC on Tuesday, citing new science on the transmissibility of the delta variant, changed its mask guidance to now recommend everyone in areas with substantial or high levels of transmission -- vaccinated or not -- wear a face covering in public, indoor settings.

Delta variant leaves vaccinated, unvaccinated with similarly high viral loads: CDC
Data shows that the delta variant leaves vaccinated and unvaccinated people with similarly high viral loads, CDC Director Dr. Rochelle Walensky said in a statement Friday.
"High viral loads suggest an increased risk of transmission and raised concern that, unlike with other variants, vaccinated people infected with Delta can transmit the virus," Walensky said.
"This finding is concerning and was a pivotal discovery leading to CDC’s updated mask recommendation" this week, Walensky said.
