Chicago cancels classes after teachers vote for remote learning
Chicago Public Schools canceled its Wednesday classes after the Chicago Teachers Union voted against in-person learning amid a wave of COVID-19 cases.
All classes, both in-person and virtual, and all after-school activities have been cancelled.
"I understand your frustration and deeply regret this interruption to your child's learning," said Pedro Martinez, chief executive of the schools. "We want out children back in their classrooms as soon as possible and will continue working with the CTU to reach an agreement that addressed their concerns and that is in the best interest of all in our CPS community, especially our children."
About 88% of the union's leadership and 73% of members voted on Tuesday to return to remote education, the union said in a statement.
"To the parents and guardians of this city, we want you to know that when you put your children in our care we put their well-being and safety first," the union said in a statement. "We fight for your children like they are our own, because they are. As this pandemic continues, we will do everything in our power to ensure that our classrooms are the safest and healthiest places for your children to learn, thrive and grow."
Teachers were being locked out of their Google Classrooms, the union said on Twitter.
Mayo Clinic lays off 1% of staff for vaccine noncompliance
Mayo Clinic said it will lay off about 1% of its staff for failing to get at least one dose of the COVID-19 vaccine by a company deadline.
"While Mayo Clinic is saddened to lose valuable employees, we need to take all steps necessary to keep our patients, workforce, visitors and communities safe. If individuals released from employment choose to get vaccinated at a later date, the opportunity exists for them to apply and return to Mayo Clinic for future job openings," Mayo Clinic said in a statement to ABC.
Last October, Mayo Clinic had set a Jan. 3 deadline for all employees to get at least their first vaccine dose or face dismissal.
The health care organization said the number of staffers being let go was "comparable to what other health care organizations have experienced in implementing similar vaccine requirement programs."
Mayo Clinic employs about 73,000 people, according to its website.
FDA: Do not swab your throat with at-home COVID-19 tests
The FDA is warning people not to swab their throats as part of an at-home COVID-19 test.
In a statement obtained by ABC News, the FDA said that is not how the tests were designed and it could pose a safety concern.
"The FDA advises that COVID-19 tests should be used as authorized, including following their instructions for use regarding obtaining the sample for testing," the statement said.
Social media posts promoting at-home COVID-19 rapid test swabbing techniques claim that throat swabs collect a better sample. However, this hasn't been proven for currently authorized tests.

Biden doubles Pfizer antiviral pill purchase
President Joe Biden announced Tuesday afternoon that he was doubling the federal government's purchases of Pfizer's COVID-19 antiviral pill, from 10 million to 20 million treatment courses.
"They’re a gamechanger and have the potential to dramatically alter the impact of COVID-19, the impact it's had on this country and our people,” Biden said.
He also warned that those who remain unvaccinated "will die" during the ongoing omicron surge.
“So there's no excuse, no excuse, for anyone being unvaccinated,” Biden said.

CDC director responds to criticism of COVID-19 guidance
Dr. Rochelle Walensky, director of the U.S. Centers for Disease Control and Prevention, is standing by her agency's new quarantine and isolation guidance for COVID-19, which the nation’s largest association of physicians has criticized as "confusing."
The CDC updated its guidelines on Dec. 27, saying asymptomatic people who test positive for COVID-19 should self-isolate for five days rather than 10. In a scathing statement released Wednesday night, the American Medical Association (AMA) said the new recommendations "are risking further spread of the virus."
"The American people should be able to count on the Centers for Disease Control and Prevention (CDC) for timely, accurate, clear guidance to protect themselves, their loved ones, and their communities. Instead, the new recommendations on quarantine and isolation are not only confusing, but are risking further spread of the virus," the AMA's president, Dr. Gerald E. Harmon, said in the statement. "With hundreds of thousands of new cases daily and more than a million positive reported cases on January 3, tens of thousands -- potentially hundreds of thousands of people -- could return to work and school infectious if they follow the CDC’s new guidance on ending isolation after five days without a negative test."
But Walensky defended the new guidance, telling ABC News' Cecelia Vega in an interview Friday on "Good Morning America" that the CDC "make[s] these recommendations in the context of science, in the context of ongoing epidemiology and in the context of what is feasible in collaboration with our public health and local and state public health partners."
"I've read the AMA statement and I have deep respect for the AMA," Walenskey said, "but I will also say we've heard a lot of support for ongoing guidance from public health partners, from other clinical and laboratory partners as well."
Walensky referenced "dozens of studies" that have shown a COVID-19 patient is most infectious in the one to two days before symptoms and the two to three days after symptoms.
"So by five days after your symptoms, the vast majority of your contagiousness is really behind you," she said. "And what we say at day five then is, are your symptoms gone? Are you feeling better? Is your cough gone, sore throat gone? And if so, then it is safe to go out if you are wearing a mask all the time. And that means not going out to restaurants, not going out to gyms, not going out and visiting grandma, but really conscientiously wearing your mask for those last five days."
Walensky noted that people may choose to take an antigen or at-home test at day five, if they have access to one. But it's not required.
"If that test is positive, you should stay home for those extra five days. But if that test is negative you should go out and continue to wear your mask," she said. "You know, these tests are actually not authorized for the purpose of evaluating contagiousness."
