Idk how old OOP is, but I’m almost 30 and I never got a polio vaccine. My mum was very diligent getting me vaccinated too, I got all the whoopng cough, measles etc. shots. Even got tuberculosis for some reason, but polio was considered so near extinct that it wasn’t on the list.

(thanks for making me check my vaccination passport to confirm this btw, found out this way that I need to get something refreshed)
