In Austria, people over 12 who are not vaccinated are currently almost completely locked down, only allowed outside for absolutely essential tasks like food or medical appointments.

In an interview she gave to the BBC, the EU chief said that it was "understandable and appropriate" to consider vaccine mandates, especially due to the new Omicron variant of COVID 19, which has been now detected in 12 different member nations of the EU.

"How we can encourage and potentially think about mandatory vaccination within the European Union? This needs discussion. This needs a common approach, but it is a discussion that I think has to be led," commented von der Leyen to the BBC.

The WHO, however, has strongly encouraged countries not to enact travel bans because of Omicron, and further iterated that early data points to the fact that most Omicron cases are not severe. Most of the world's governments are not paying attention to the WHO's guidelines on this occasion, however.
