So now that the dust has settled and we are not creationists and we are in fact pro-scientific people that adhere to the literature and prevailing scientific theories and we of course know these vaccines work, how should academics, the pharmaceutical industry and medical professionals address the possibility of creating indefinite and possibly even more pathogenic variants of sars-CoV2 through vaccinating healthy, non-vulnerable and young individuals and therefore creating increased artificial selective pressures?

You're not a creationist that denies science are you? I mean, you understand the basic principle of not over-prescribing antibiotics to make sure that normal or pathogenic flora doesn't become resistant and creates 'superbugs' (as they are colloquially known in those that are not as scientifically literate as us), do you?
