COVID-19 updates: Austria orders nationwide lockdown for unvaccinated residents
The lockdown for unvaccinated residents began at midnight on Monday.
As the COVID-19 pandemic has swept the globe, more than 5 million people have died from the disease worldwide, including over 763,000 Americans, according to real-time data compiled by Johns Hopkins University's Center for Systems Science and Engineering.
Just 68.8% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the U.S. Centers for Disease Control and Prevention.

Biden administration urges schools to provide COVID-19 shots, info
The Biden administration sent letters to superintendents and principals across the United States on Monday, urging them to set up COVID-19 vaccination clinics inside their elementary schools.
"Parents rely on their children’s teachers, principals, school nurses, and other school personnel to help keep their students safe and healthy every school year," U.S. Secretary of Health and Human Services Xavier Becerra and U.S. Secretary of Education Miguel Cardona wrote in the letters. "We need your help now more than ever to continue to protect our communities and our children."
They also asked the school leaders to distribute information "from trusted sources" about COVID-19 vaccines to all families with children ages 5 to 11, and to host community engagements with parents in partnership with local pediatricians and "other trusted medical voices" in the community.
"The communications you issue -- in languages accessible to your parents -- will be critical in helping families learn more about the vaccine," Becerra and Cardona wrote.
The letters went out on the same day that first lady Jill Biden and U.S. Surgeon General Vivek Murthy plan to visit an elementary school in McLean, Virginia, that was used as one of the first sites in the country to begin administering the polio vaccine in 1954.
School officials would not be responsible for handling COVID-19 vaccines or giving shots to students. Instead, they would partner with a local vaccine provider already administering shots, such as a pharmacy or community health clinic.
The schools would be allowed to use federal dollars through the American Rescue Plan to offset any costs with providing the space and organizing the vaccine drive.

Pfizer asks FDA to amend booster authorization to include all adults
Pfizer is asking the FDA to amend its booster authorization to include all adults 18 and older.
In September, the FDA and CDC authorized Pfizer booster shots after six months for anyone older than 65 and younger adults with a high risk of developing COVID-19. But the agencies stopped short of recommending a Pfizer booster for all adults, saying data was insufficient to recommend boosters for everyone.
Since then, Pfizer published new data from its Phase 3 trial showing that a booster shot raises vaccine efficacy against symptomatic infections to 96% -- regardless of the person’s age. Now, the company is asking the FDA to broaden its authorization so that everyone over the age of 18 would be eligible for a booster shot. The FDA still needs to review this request.
