I for one really hope the T cell resistance is a big thing but, whilst we don’t know this yet and have no way yet of finding out, it’s not something that a best practise can be based on. The one good thing nowadays is that hospital cases and deaths are still well down which maybe gives some hope that perhaps the covid strain is weakening a bit.
All the same I still think the way we are doing things now (ignoring the shit show earlier in the year obviously) is the best way to proceed. Social distancing, masks on in shops, gradually open things up, work from home if you can and apply local lockdowns (or international ones) to fire fight. Oh and fining illegal rave and gathering organisers too
