Is there current data for CFR for unvaccinated persons who had “original” COVID (basically all cases in 2020) vs. unvaccinated persons who got Delta? This would have to be in a single country and likely needs to be broken down by age group.
Interesting. Maybe profiling by months. Delta reached 90% in early June 2021. Original virus June 2020.
Hmmm. There will be difficulty with differences in testing density determining case count.
This is a big reason why I got the global result. The numbers and seasons an countermeasures could average out to 1.9%.
