Re: eliminating COVID-19 will be easier than polio
What you seem to have managed to omit is that vaccinated people who do get infected have far fewer and lesser symptoms, if any.
Yes you can still catch Covid if you are vaccinated but if you do it'll do far less damage than if you weren't vaccinated.
Considering the long term problems associated with C19, vaccination is definitely a benefit and not taking it because of some lunatic conspiracy theory is most certainly idiotic.
