I had two jabs in 2021 and never got Covid.
My DIL, grandson and granddaughter have been getting jabbed every year - liberal DIL - and none of them got Covid.
I can understand genetically about grandson and granddaughter being like me and never getting it but puzzled about the DIL who is not related and works as school secretary in a public grade school.
No control group. Might you all have remained covid-free without the jab? The world will never know.
