Public officials around the world are imposing new restrictions on the unvaccinated as many nations struggle to raise their COVID-19 vaccination rates.

Why it matters: Unvaccinated people are five times more likely than those vaccinated to get infected and 10 times more likely to die from the coronavirus, per the Centers for Disease Control and Prevention. Many health care systems are buckling under new waves in cases among the unvaccinated.

Driving the news: Austria's chancellor imposed a "lockdown for unvaccinated people" age 12 and older, per DW. It's designed to lift the vaccination rate, which has stalled at 65%. From Monday, unvaccinated Austrians can only leave home for work, medical reasons or to get groceries under the order.

• The Singaporean government announced last Monday that it will stop covering medical bills for people who are "unvaccinated by choice" after Dec. 8.
• The New Zealand government has announced a business vaccine mandate that affects 40% of its workforce. Businesses including hair salons, bars, and gyms must ensure all staff are vaccinated in order to operate under the upcoming order.
• In New South Wales, Australia, unvaccinated people over the age of 16 are no longer allowed to visit another person’s residence, except in limited circumstances. 
• Some German states have barred people who are eligible for vaccination but choose not to get it from indoor venues like restaurants and clubs, according to France 24.

The big picture: Roughly 40% of the world's population is fully vaccinated, per data from Johns Hopkins University.

Worth noting: The U.S. has faced censure from international experts and the World Health Organization for pursuing booster shots instead of distributing vaccines to lower-income countries.
