COVID-19 updates: Austria orders nationwide lockdown for unvaccinated residents

Ten states are suing the Centers for Medicare and Medicaid Services over the Biden administration's vaccine mandate targeting health care workers.

About 17 million health care workers who are employed at places that get funding through CMS are required to get vaccinated by Jan. 4, 2022. They do not have the option to test.

"The mandate is a blatant attempt to federalize public health issues involving vaccination that belong within the States’ police power," stated the suit, which was filed by Missouri Attorney General Eric Schmitt, a Republican who is running for Senate.

The attorneys general of Nebraska, Arkansas, Kansas, Iowa, Wyoming, Alaska, South Dakota, North Dakota and New Hampshire have joined the lawsuit, which is one of many filed against different parts of the Biden administration's vaccine requirements but the first to target the health care worker mandate.

Twenty-six states are suing over the mandate that applies to businesses, while another handful are suing over the federal worker mandate. Last week, a federal court temporarily blocked the business vaccine rule.

The U.S. daily case average has jumped by 15% since the end of October, according to federal data.

Twenty states have seen daily cases jump by at least 10% in the last two weeks: Arizona, California, Colorado, Illinois, Indiana, Iowa, Maine, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, Nevada, New Hampshire, New Mexico, New York, Utah, Vermont and Wisconsin.

Cases are still falling in most of the South, which was the first region to get hit hard by the delta surge over the summer. In Florida, where high transmission was reported in every county over the summer, now only 1 out of the 67 counties is reporting high transmission, according to federal data.

White House COVID coordinator Jeff Zients said Wednesday that the pace of vaccines for kids is expected "to continue to accelerate across the coming days and weeks."

CDC director Dr. Rochelle Walensky made the case that children get vaccinated against far less deadly vaccines. 

"In the years prior to the recommendation for Hepatitis A, meningococcus and varicella vaccination, the average annual reported deaths from these infections were three, eight and 16 respectively," she said. "All of those numbers are far lower than 66 -- the number of deaths we have seen from COVID-19 in children 5-to-11 over the past year."

The White House estimates that by the end of Wednesday over 900,000 children ages 5 to 11 will have received their first vaccine shot.

That’s 3% of the 28 million newly eligible kids in this category.

Another 700,000 kids in that age range have appointments booked at pharmacies to get their first jab, according to the White House.
