data?
I got data!
Protection offered from prior infection was 81.8% (95% confidence interval 76.6 to 85.8), and against symptomatic infection was 84.5%

(except it’s against wild wuhan 2020 and shows acquired immunity is about as effective as vaccine immunity - 2021 Delta affects the percentages of both wild wuhan and vaccine)
Why do you call a 'virus' intentionally created and released 'wild wuhan'?
There's your problem right there, Granny Plum. You don't have a fundamental understanding of wtf is going on here. That's why all your words are wind.
