If vaccinated you can still get infected and test positive, but the symptoms are significantly reduced. Though not fully confirmed, the risks of long covid complications are also significantly reduced.
So when we get to the stage that everyone has been OFFERED a vaccine, then we can move to a phase where virus can be allowed in the community. Those that are vaccinated will be not become ill from it, and those that choose not to get vaccinated can live with that risk of illness.
