Once the vaccines become widely available I think the situation will become like kids going to school. You can choose not to be vaccinated BUT you will then be denied entry to certain events/locations like sports events, concerts, hospitals, rest homes, etc. where the chances of transmission are high.
Now that's just my speculation. Haven't seen it predicted any where else but if they can deny kids entry to schools without vaccination then this would be similar with Covid-19 being so contagious.
By the way I believe that requiring vaccination for certain things was already ruled legal by the Supreme Court a long time ago.
