We’re approaching the year-and-a-half mark of the globe’s collective experience with the SARS-CoV-2 virus and the Covid-19 pandemic it has triggered. At this point, it’s fair to assume people the world over are asking themselves the same two questions: How will this end? And when?
There may have been a fleeting chance humans could have halted spread of SARS-2 and driven it back into nature, as happened with its cousin, SARS-1. But that door was firmly shut long ago. It also seems that another option — vaccinating our way out of the pandemic — is an expensive toll highway that few countries will be able to access in the near term.
That probably sounds bleak, but don’t despair. The truth of the matter is that pandemics always end. And to date vaccines have never played a significant role in ending them. (That doesn’t mean vaccines aren’t playing a critical role this time. Far fewer people will die from Covid-19 because of them.)
