Several Paralympic athletes have tested positive for COVID-19 in Tokyo in recent days.

According to daily figures released by the Tokyo 2020 organizing committee, at least eight positive cases have been confirmed among unnamed Paralympic athletes so far, with two new cases reported on Wednesday following the opening ceremony.

The 2020 Summer Paralympics officially opened in the Japanese capital on Tuesday, after a yearlong delay due to the coronavirus pandemic. Like the 2020 Olympics, which ended on Aug. 8, this year's Paralympics is taking place under a state of emergency as Japan struggles with a growing COVID-19 crisis.

Leaders of the Orange County public school system voted Tuesday to require a mask mandate for all students and staff.

The rule goes into effect on Aug. 30 and will last for at least two months. There will be exemptions for medical reasons.

School board members cited the growing COVID-19 rates and hospitalizations in the area as the reason for their decision.

“Doctors are.

New York City Schools Chancellor Meisha Porter spoke with ABC News about the vaccine mandate for public school staff that goes into effect Sept. 27.

Porter said she was confident that teachers and other staff members would comply to ensure that classrooms are safe for everyone.

"This is the additional extra layer of protection that we didn't have a year ago," she said.

Porter said she has been in discussions with the United Federation of Teachers over what the penalties will be if a teacher doesn't comply, and she was told that "many of their members are already vaccinated."

The chancellor said those who still have concerns should know that the Food and Drug Administration has fully approved the Pfizer vaccine and it has shown to prevent severe illness.

Kentucky Gov. Andy Beshear tweeted a dire update on the state's COVID-19 cases.

The state health department reported that 2,014 people are currently hospitalized with the virus, 589 of whom are in intensive care units and 338 are on ventilators. Beshear said these are record numbers.

"Folks, this is dangerous. Please, get vaccinated and mask up indoors," the governor tweeted.

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.
