GP was referring to a limited subset of data that gives an incorrect picture of what the R0 is. I was trying to point out why that data is the wrong set to draw

  Yea, I skipped that part of your comment as meaningless. RO excludes vaccinations and prior infections by definition. https://en.wikipedia.org/wiki/Basic_reproduction_number https://en.wikipedia.org/wiki/Basic_reproduction_number In epidemiology, the basic reproduction number, or basic reproductive number (sometimes called basic reproduction ratio or basic reproductive rate), denoted R 0 R_{0} (pronounced R nought or R zero),[1] of an infection is the expected number of cases directly generated by one case in a population where all individuals are susceptible to infection.[2] The definition assumes that no other individuals are infected or immunized (naturally or through vaccination). Some definitions, such as that of the Australian Department of Health, add the absence of "any deliberate intervention in disease transmission". I assume your concerned about transmission, but that’s not a constant when you include vaccinations reducing infection severity.
