Vaccine Hesitancy and the Future of the Pandemic

There’s an article today in the Times which reports that we may never reach ‘herd immunity’ for COVID or at least that we may not do so for a very long time. The article strikes me as needlessly alarmist, in part because the ‘news’ being reported is as much a question of semantics or people being informed about epidemiology as it is some new negative development in the course of the pandemic. The details are probably what you would expect, a mix of vaccine hesitancy, more transmissible viral strains and viral evolution that slowly chips away at vaccine immunity all working together to put ‘herd immunity’ out of reach. But I want to zoom in on the potential role of vaccine hesitancy or politics-driven resistance to vaccines.
