COVID-19 updates: No unemployment benefits for vaccine refusal in this state

The United Kingdom and South Korea have agreed to share COVID-19 vaccine doses to mutually support the rollout of shots in each nation.

The U.K. will send 1 million of the Pfizer-BioNTech vaccine doses to South Korea to enhance their vaccination program, with the first batch of shots expected to arrive in the coming weeks. South Korea will return the same volume by the end of the year, as the U.K. presses ahead with its vaccine rollout and booster shot program over the winter months, according to a press release from the U.K. Department of Health and Social Care.

The swapping initiative, similar to the arrangement between the U.K. and Australia, will help South Korea toward hitting its target of administering a second dose to 70% of its population by the end of October.

"The Republic of Korea is a strategic partner for the UK and the sharing of one million vaccines benefits both countries as we help build resistance against COVID-19 and save lives," British Foreign Secretary Liz Truss said in a statement Tuesday.

The deal will have no impact on the U.K.'s ongoing vaccine rollout or booster shot program, nor will it effect the doses the country has already pledged to give to the global vaccine-sharing initiative COVAX. Almost 90% of people over the age of 16 in the U.K. are fully vaccinated against COVID-19, and Pfizer-BioNTech vaccine doses are not immediately required in the U.K. due to robust supply management, according to the U.K. Department of Health and Social Care.

Brazilian Minister of Health Marcelo Queiroga said Tuesday that he has tested positive for COVID-19 while in New York City for the United Nations General Assembly.

Queiroga, who accompanied Brazilian President Jair Bolsonaro to the event, announced his diagnosis on Twitter and said he will quarantine.

In a letter to the Texas Education Agency, the U.S. Department of Education on Tuesday said it is beginning an investigation into Texas schools' ban on mask mandates, and how that could potential be an infringement of students’ civil rights.

The investigation will focus on "whether, in light of this policy, students with disabilities who are at heightened risk for severe illness from COVID-19 are prevented from safely returning to in-person education, in violation of Federal law,” the letter states.

The Department of Education’s acting assistant secretary for civil rights, Suzanne Goldberg, laid out the process of the investigation in the letter, but also made clear that it could be resolved at any time if masks in schools are reinstated.

"OCR’s Case Processing Manual provides several ways for this investigation to be resolved, including an option to reach a voluntary resolution agreement prior to the completion of an investigation,” the letter reads. “If TEA expresses an interest in resolving the investigation in this way and OCR determines this form of resolution is appropriate based on the investigation, we will follow the steps set out in Section 302 of the Case Processing Manual.”

The U.S. daily death average has now climbed over 1,400 despite skewed reporting from the weekend, according to federal data.

About one-third of the nearly 9,500 virus-related deaths in the last week came from just three states: Texas, Georgia and Alabama.

About 90,000 Americans are currently hospitalized with COVID-19, compared to more than 100,000 patients about three weeks ago, according to federal data. But in the past month, at least 10 states -- Alaska, Idaho, Kansas, Maine, North Carolina, Oregon, South Carolina, Tennessee, Washington and West Virginia -- have reported record hospitalizations.

West Virginia is leading the nation in cases, followed by Alaska, Montana, Idaho, Alabama, Wyoming, Kentucky, North Dakota, Tennessee and Ohio, according to federal data.
