It appears to be advantageous for the natural immunity to work stratified by age/metabolic health.
It is helped by early interventions like ivermectin etc.
The circulating B cells paper on “Spanish” flu is fascinating.
With a case fatality rate of less than 3% around 50 million people died.
So we are assuming that natural immunity saved…

The circulating B cells paper on “Spanish” flu is fascinating.
With a case fatality rate of less than 3% around 50 million people died.
So we are assuming that natural immunity saved around 97% infected.
About 50% of deaths were in the age group 20/40 where you would expect a robust immune response.
With death possibly caused in the majority of cases by bacterial pneumonia.
