We don't have mandatory smallpox vaccines in Austria anymore, even though we had them in the past. I really see no way how these energency powers will stay.
But is that a bad thing necessarily? If we have powers that we can use in emergency situations and there's precedent they will only get used in such, isn't that the ideal state?
Looking at the US, because they keep good records on emergencies, it has been unlikely for an emergency situation to end from around 1994. There appears to still be an ongoing emergency that started in 1979.
This is a relative strong precedent in the west of emergency powers being used in an ongoing way.
