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.

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.
