Wake up. Stop kidding yourelf.
We all want to get back to as normal a life as possible, but that wont be fr a long while - and only if everyone treats this virus more responsibly this late spring and summer than they did last late spring and summer...government most of all.
But the answer to stop people getting ill is the vaccine, isn't it? Vaccine resulting in herd immunity, like any other illness.
So what difference does it make once the populations are vaccinated? The virus will be suppressed, just as it is in NZ.
Once that has happened, then stuff will and should be back to normal, but there will obviously just be elements of things like track and trace (i.e. getting a proper one that works for western nations in place), perhaps care workers etc having to get regular tests, wearing masks on public transport or in supermarkets?
Other than that... what difference does it make if that happens this year or in 5 years as long as everyone is vaccinated?
