First and foremost SARS-CoV-2 will never go away because it infects animals. Because it is so infectious, it will go through an entire herd or farm within days and eventually cause mutations and jump back to humans. So it will never go away and we need to prepare for it. The main goal is to make it survivable, ie. akin to the flu, and not cause hospitals to get overrun like we have seen so many times around the world…
This is also one of the main mechanisms for antibiotic resistance in bacteria that infect humans[1].
