COVID-19 vaccinations in Houston increased more than five-fold on Thursday as the city launched a new incentive program.

The Houston Health Department is now providing up to $150 in gift cards to get vaccinated against COVID-19. A total of 740 vaccine doses were administered at the health department's eligible sites on Thursday, the first day of the program, marking a 51% increase over Wednesday's total of 121 doses.

Of the total shots administered Thursday, 658 were first doses and 82 were second dose, according to a press release from the health department.

The U.S. Supreme Court suspended the Center for Disease Control and Prevention's nationwide eviction moratorium in an unsigned, 6-3 opinion Thursday night

"It is indisputable that the public has a strong interest in combating the spread of the COVID–19 Delta variant. But our system does not permit agencies to act unlawfully even in pursuit of desirable ends," the court wrote. "It is up to Congress, not the CDC, to decide whether the public interest merits further action here."

"If a federally imposed eviction moratorium is to continue, Congress must specifically authorize it," it continued. "The application to vacate stay presented to THE CHIEF JUSTICE and by him referred to the Court is granted."

Liberal justices Sonia Sotomayor, Stephen Breyer and Elena Kagan dissented.

White House press secretary Jen Psaki lamented the Supreme Court's ruling, saying the CDC moratorium "saved lives by preventing the spread of the COVID-19 virus."

"As a result of this ruling, families will face the painful impact of evictions, and communities across the country will face greater risk of exposure to COVID-19," Psaki said in a statement, before reiterating President Joe Biden's call for states, localities, landlords and local courts to do what they can to prevent evictions.

The Biden administration has repeatedly called on Congress to act in regard to the eviction moratorium, but Republicans have opposed the proposals.

The CDC had issued a 60-day extension to the moratorium the first week in August after the previous one expired July 31.

Every state in the country is now reporting high community transmission of COVID-19, according to newly updated federal data.

In mid-June, no states were reporting high transmission, and just six states were reporting substantial transmission. Now, 10 weeks later, all 50 states are in that category, according to data from the Centers for Disease Control and Prevention.

The development comes as the delta variant has also rapidly spread. In June, the highly contagious variant accounted for just 26.4% of all new COVID-19 cases in the U.S.; today, it accounts for nearly 99%, according to the CDC.

The U.S. is continuing to experience its steepest increase in COVID-19 hospitalizations since the winter of 2020, with more than 101,000 patients now in hospitals, according to federal data. This marks the highest number of patients in seven months.

Eight weeks ago, there were under 12,000 patients receiving care.

The country's daily death average has increased to more than 800 deaths per day. This is a 317% jump in the last seven weeks and marks the highest average since mid-March 2021.

Japan has suspended the use of about 1.63 million doses of Moderna's COVID-19 vaccine due to reported contamination, as the country grapples with surging infections.

Japanese drugmaker Takeda Pharmaceutical Co., which is in charge of distributing the Moderna vaccine in Japan, said in a press release Thursday that it has received reports of foreign substances in some unused vials at multiple inoculation sites. Although some doses might have been administered, Takeda said there have been no reports of safety concerns tied to the affected vials so far.

After consulting with Japan's Ministry of Health, Labor and Wealth, Takeda said it decided as a safety precaution to stop using doses from three separate lots, manufactured in the same production line as the contaminated vials. The company said it has requested Moderna to conduct an emergency investigation into the issue.

For doses from non-suspended lots, Takeda urged people to check the vials for discolouration, foreign substances or other abnormalities before continuing to use. Meanwhile, the Japanese health ministry said it will work with Takeda to supply alternative doses in an effort to minimize the impact on the country's vaccination progress.

Moderna told ABC News that it has put the 1.63 million doses on hold in Japan after being notified that some of the vials may have been contaminated. One of the three lots received "several complaints of particulate matter" in its vials, the American drugmaker said, while the two other adjacent lots were put on hold out of "an abundance of caution" and for continued assurance of quality.

According to Moderna, the manufacturing issue may have come from one of the lines used at its contract manufacturing site in Spain. The Massachusetts-based company said it is looking into the contamination reports and "proactively communicating with Japan’s health authorities and its partners as the investigation proceeds." Moderna added that it remains "committed to working transparently and expeditiously" with its Japanese distribution partner and with regulators to address any potential concerns. No safety or efficacy concerns have been identified so far, the company said.

Moderna noted that the pause in Japan does not impact doses distributed in the United States, or put the American supply at risk in any way.
