Yeah but that's a worst case scenario. You might as well say that by 2036 Barnsley Football Club could be playing in the National League. It's just as likely IMHO.
So do I. It would mean everyone regardless of age or underlying health conditions can live the normal life they have before Covid came along. But should they show signs like shivering but with a high temp they could ring 111 or 999 and someone can come test them straight away at their house and if they have it get them sent to hospital and straight on to one of the drugs they think works at making people better before their condition got worse over the coming days, which is what has happened so far because testing levels have been so poor.
