Let be fair: certainly maladies like polio HAVE been eradicated by vaccines. We can probably put rabies (yes...I know...animals...work with me) and tetanus on that list as well. These are net benefits to society, and a great example of eradication policy making good on its promise.
But let's be honest as well: if COVID19 is akin to influenza insofar as it mutates, abates then returns, afflicts the weak and those with comorbidities, AND (here's the big one) is tamed - but not cured - by immunizations (influenza vaccines recently were maybe 50% effective), then an honest discussion should emanate.
Or, being blunt, this bug isn't polio and the vaccine - perhaps helpful as a management tool - won't render people immune for life. Promising eradication via vaccination is like promising the end to world hunger...
