You realize that the way other diseases were eradicated required the cooperation of everyone on earth? Or at least in most countries. The reason we don't get polio in virtually any country on earth is because of global cooperation in the face of a disease with a known mitigation. Barely 500 known cases world-wide in 2019. Thanks to global cooperation. Too bad propaganda and social media probably ruined our chances of repeating such a feat...

The polio vaccine being a sterilizing one is certainly a _major_ reason for its success. The Covid vaccine, by contrast, does not confer sterilizing immunity. Polio also spreads through contaminated food and water, not the exhaled breath of the infected. So other than those minor things, great comparison.
I'd say another major reason for the polio vaccine's success is the whole world took it. Substitute mumps, measles, rubella, smallpox, whatever you'd like. Anyway you totally missed the point about global cooperation. We know masks, social distancing, and vaccination with enough cooperation could end the pandemic, but no, people just won't cooperate.
