(NEW YORK) -- The United States has been facing a COVID-19 surge as the more contagious delta variant continues to spread.
More than 721,000 Americans have died from COVID-19 while over 4.8 million people have died from the disease worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
Just 66.2% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the CDC.

Unvaccinated people had over 11 times greater risk of dying from COVID-19 in latest delta surge
The CDC updated its website with data previously released last month that shows vaccines still dramatically reduce the risk of testing positive or dying from COVID-19, even amid the latest delta surge.
In August, unvaccinated people had an over-six times greater risk of testing positive for COVID-19 and over 11 times greater risk of dying from the virus, compared to the vaccinated, according to federal data pulled from 16 states and jurisdictions.
In every age group, the death rate was higher for COVID-19 among unvaccinated populations. Americans 80 and older had the highest rate of deaths among fully vaccinated people per capita, though their risk of death was about 5.7 times lower than their unvaccinated counterparts in the same age group.

Undefeated Cardinals to be without head coach for Browns game
Arizona Cardinals head coach Kliff Kingsbury will miss Sunday's road game against the Cleveland Browns after he tested positive for COVID-19, the team announced Friday night.
Kingsbury, 42, has led the hottest team in the NFL this season. Arizona (5-0) is the only undefeated team left in the league.
Sunday's game figures to be one of the biggest of the week, with the 3-2 Browns suffering only two narrow losses coming off a playoff appearance last year and expectations to contend for a title.
The Cardinals will also be without quarterbacks coach Cam Turner and defensive lineman Zach Allen, who each tested positive Friday. Star outside linebacker Chandler Jones was put on the COVID list earlier this week and won't play.
Kingsbury told reporters exactly three weeks ago that 100% of the Cardinals' roster was vaccinated.
Defensive coordinator Vance Joseph and special teams coordinator Jeff Rodgers will split head coaching duties against Cleveland.

FDA panel votes to authorize booster shots for J&J vaccine
An independent FDA panel has voted to move forward with Johnson & Johnson vaccine boosters.
The panel’s decision on J&J was broader than for Moderna and Pfizer as it applies to all J&J recipients 18 and older. The timing is also different: The J&J booster can be administered two months after the initial shot.
The 19-person panel voted unanimously.
Johnson & Johnson's one dose has shown to be 85% effective against severe illness, but adding a second dose boosted that to 100%.
Penny Heaton, a J&J executive, acknowledged Friday that J&J’s efficacy is below the mRNA vaccines but said they would be on par if they used a booster.

CDC advising states to preorder Pfizer's vaccine for young children
The U.S. Centers for Disease Control and Prevention is advising states to order Pfizer's COVID-19 vaccine doses for children ages 5 to 11 ahead of a vote on its authorization.
An independent Food and Drug Administration advisory panel is scheduled to discuss the vaccine on Oct. 26, and a vote is expected soon after. In planning documents posted by the CDC, the agency is advising states to order their doses in advance of the meeting, with preorders starting Oct. 20.
This is meant to "ensure that vaccine can be placed in many locations nationwide, making it easier for children to get vaccinated" and "allow for a manageable and equitable launch," the CDC said.
A decision from the CDC on recommending the vaccine is not likely until early November; the CDC's Advisory Committee on Immunization Practices is scheduled to meet on Nov. 2 and Nov. 3.

The recommendation is in line with what the FDA and CDC authorized for Pfizer booster shots last month.
The FDA panel will meet on Friday on J&J boosters. Following next week's meetings from the CDC’s independent advisory group, Moderna and J&J boosters could be authorized and recommended for specific populations as soon as Oct. 22.
