Answer For Derps: polio vaccine isn’t 100% effective. How many people surround you that have polio (zero)? After a successful vaccination campaign the disease is pretty much non-existent in North America. If people carrying polio were all over the place like COVID, you would see what you are seeing now with the COVID vaccine and some positive tests after vaccination.

Polio was pretty much eradicated with vaccines because there was a time before the internet.


Polio vaccine efficacy: "99% to 100% effective" (source: https://www.cdc.gov/vaccines/vpd/polio/hcp/effectiveness-duration-protection.html).
Coivd vaccine efficacy: " estimated to be 93%" with third booster. (https://pubmed.ncbi.nlm.nih.gov/34756184/)

One of these things is not like the other. One of them will eradicate a virus from a population and the other won't. Care to guess which one is which?

Polio was also mainly spread through contaminated water and poor sanitation. So sewers helped end polio as well.
