The lockdown, at least in Austria, is because they are running out of ICU beds.
I'm wondering what's the long-term strategy, in general, too. The virus isn't likely to go away. There are no sterilising vaccines and efficacy of the current ones wanes sharply in months, requiring boosters and then likely boosters of boosters for a foreseeable future. The virus will also keep on mutating, and since it can still infect vaccinated people, there's the danger of vaccine-resisting and immune system evading strain emerging due to selective pressure.
So what's the plan here? Vaccine mandates, "green passes" allowing only fully vaccinated individuals to take part in society, and winter lockdowns forever? How is it all going to be implemented? QR codes and ID checks for entering any public space and transportation? How many shots will a person need to be considered fully vaccinated, and when will that status expire, requiring another booster? Will it even be possible to maintain vaccination levels of 90%+ of the population constantly for years?
