It's only an estimate. It's closer to only 20 percent not producing antibodies. Some percentage of that is people having immuno compromise and not developing humeral immunity even though they've likely been exposed. Then there's testing failure. None of these tests are 100 percent sensitive.

I do believe though like what. Ten to fifteen percent of people have isolated for three years and not gotten it. I'd buy that for sure. And there are a lot of places where you just don't encounter people often. People that naturally were distanced from others just sort of...kept doing what they were doing.
