The U.S. Centers for Disease Control and Prevention released its latest vaccine numbers Sunday afternoon and revealed that over 209.2 million Americans 12 and older have received a COVID-19 vaccine dose.

That represents 73.8% of all Americans 12 and older, the agency said.

In 13 states, over 80% of the population has at least one dose, CDC data shows.

Hawaii is in the lead, as 88% of its residents have at least one shot, according to the CDC. West Virginia is last, as just 54.6% of its residents over 12 have at least one dose, the CDC data shows.

More than 40.9 million COVID-19 cases have been confirmed in the U.S. since the pandemic began, according to Johns Hopkins University's Coronavirus Resource Center.

And more than 659,000 Americans have been killed by the virus.

The city of West Hollywood, California, issued an emergency executive order Friday requiring patrons to show proof of COVID-19 vaccination to enter the indoor portions of businesses such as restaurants, bars and gyms.

The order comes “as the transmission rate of the COVID-19 delta variant remains high in Los Angeles and throughout the entire nation,” the city said in news release.

Anyone 18 or older must show proof of vaccination prior to entering “any indoor portion of a facility, subject only to certain exceptions.” The requirement should be enacted “as soon as possible but no later than Oct. 11.,” according to the order. 

Individuals who do not provide proof of full vaccination will be allowed to use outdoor portions of business facilities.

Other businesses affected by the order include nightclubs, theaters, cannabis consumption lounges and entertainment venues as well as yoga studios and tattoo parlors. 

Employees 18 and older and all affected businesses must “ensure all staff who routinely work onsite provide proof of full vaccination before entering or working in any indoor portion of the facility” by Nov. 1.

Some 74 million Americans eligible for the vaccine still aren't vaccinated, White House COVID-19 Data Director Cyrus Shahpar said Saturday.

Still, many are flocking to get their shots with “+903K doses reported administered over yesterday’s total,” Shahpar said, with 395,000 of them being new vaccinations. 

The Texas attorney general has filed lawsuits against six school districts that mandate masks, the office said Friday.

The lawsuits target the school districts of Richardson, Round Rock, Galveston, Elgin, Spring and Sherman for flouting Gov. Greg Abbott’s executive order prohibiting local entities from requiring masks -- what Texas Attorney General Ken Paxon referred to in a statement as "acts of political defiance."

In a statement to ABC News, Sylvia Wood, a spokesperson for Spring Independent School District, said the district had yet to be served and had no details about the lawsuit beyond a press release.

"Spring ISD will let the legal process unfold and allow the courts to decide the merits of the case," Wood said.

Elgin Independent School District Superintendent Jodi Duron also told ABC News the school district had not been served yet, and that schools in Travis County, part of Elgin ISD, are required to have students wear masks. "To the District’s knowledge, the Travis County Order has not been suspended," she said.

Round Rock Independent School District spokesperson Jenny LaCoste-Caputo told ABC News the school district is following Texas Education Agency guidance that allows for mask requirements "for adults or students for whom it is developmentally appropriate" and is working with local authorities "who advise us that masks remain an essential tool in stemming the spread of COVID-19 in our classrooms."

Sherman Independent School District told ABC News in a statement that it had not received any information on the lawsuit yet and for now "will continue to focus on promoting a safe and healthy learning environment for our students and staff."

ABC News has reached out to the other school districts for comment.

Nearly 90 school districts currently have mask mandates, according to a list compiled by Paxton's office. The attorney general anticipates more lawsuits if school districts "continue to defy state law," his office said in a statement.

Several school districts have sued the state to challenge the ban on mask mandates.

Last week, the Texas Education Agency said it is not enforcing the governor's executive order "as the result of ongoing litigation."

Florida Gov. Ron DeSantis' school mask mandate ban was reinstated by an appeals court Friday. 

This overrules a Tallahassee judge's decision on Wednesday to lift the stay, preventing the state from enforcing the ban. (The appeals court still needs to rule on the legality of the order, but the reinstatement of the stay means that until then, the state can continue sanctioning school districts.)

DeSantis responded on Twitter, "I will continue to fight for parents’ rights."

DeSantis has struggled to rein in the state's largest school systems as they implement mask mandates in defiance of state law. At least 13 districts, including Florida's six largest, have mask requirements in place. The Florida Department of Education has threatened to withhold the salaries of school board members in most of these districts and has begun doing so in at least two cases.
