It all would come to focusing on age groups. For most young people, say under 40, if you were healthy you are at essentially no risk. If you were over 80, or even over 65 with 2-3 cobormidities then yeah, it was a big concern.

Issue that I have is that most data sets use Relative Risk Reduction over Absolute Risk Reduction which would give a better picture.

This was the percentage of risk out of death, as per the break down of actual cases @ June 2020 from 13 different countries, so 6-7 months before the shot were avaiable for different age groups. Not all countries locked down like the USA or Canada did.

Would like to see it compared to today, true.
