I tend to get every cold and flu that comes around. I was really sick with what I thought was the flu in Feb 2020. I never got covid-19 (afaik) even though I never went to great lengths to avoid it. Only wore masks when asked, and hung around all different crowds of folks - maskers and non-maskers. Got early vaccine but no boosters. Perhaps I got the early alpha or beta version of the disease and that is what has kept me well. Thus article hints that could be the case.
