That's probably less of a smoking gun than it seems like. This case was only discovered because someone actually suffered from paralysis, which is somewhat uncommon even in the unvaccinated and extremely uncommon amongst the vaccinated. The thing is, although it gives very strong protection against paralysis and death the inactivated vaccine used in countries like the US probably isn't all that effective at preventing people catching and spreading polio - all of the polio elimination efforts globally have used the oral polio vaccine which contains live virus for this reason. It's not used in the developed world because the serious side effect rate is hard to justify in a country where polio no longer exists.

I'm in the US and I had an oral polio vaccine.
Okay, I should probably have been a bit clearer about that. Polio eradication efforts everywhere in the world, including the US, were based around the oral polio vaccine due to its apparent benefits in stopping vaccinated people from spreading polio. This was discontinued in the developed world, including the USA, a couple of decades ago (edit: and replaced with the inactivated polio vaccine - I though this was clear enough from the context...) after polio was eliminated there and the risk of spread from other countries was considered low enough. Entire age groups have never been vaccinated using the OPV. And of course it doesn't matter how well protected the population as a whole is if there's a subcommunity of people who regularly interact with each other who aren;t...

Where are you getting this information from?
All those vaccinations will be the inactivated polio vaccine, since it's the only polio vaccine in use in the USA since 2000: https://www.cdc.gov/vaccines/vpd/polio/index.html
