This seems a strange speculation. Basically, one should get two covid-19 vaccine shots and a booster shot and if a breakthrough covid-19 infection happens, the result will be better future covid-19 immunity. I'm reminded of the Chautauqua tent hucksters who were tarred and feathered and run out of town on a rail. So far all of the data indicates that two shots and a booster are a prudent efficacious precaution for those 50yo and up. Likewise, all above age 10, should do social distancing and masking in enclosed crowded areas, and avoid prolonged association with strangers. The future evolution of the laboratory made SARS-Cov-2 for morbidity and mortality is both uncertain and random.
