.///// I don't believe the figure is falling because of the vaccine or because of lockdown. /////
I think that you are wrong, but entitled to your opinion.
.//// I believe the virus has killed the weakest and most vulnerable so far. ////
I agree.
////Many, many people tested positive and didn't develop the illness, let alone the disease.////
You mean haven't developed symptoms. I agree........but, they can still transmit the disease.
////People are more resistant to it than some think and now that the weakest have fallen, lots are more resistant to it. ////
That sounds good and maybe correct and that is my definition of herd immunity, but not the scientific definition, however studies have been very confusing, as to what % of the population have antibodies ranging from 5% to 45% pick which one to suit your argument either way and how long the antibodies last and to which, if any, variants the above apply.
Isolation AND vaccine are our only weapons.
