Yes, the dreaded polio shot! I do remember it. And possibly the smallpox vaccine at school, as well.
I know of several people who contracted polio, and were affected throughout their lives. And as they got older, the effects just got worse. Quite a bit of suffering and disability.
As far as current generations, it might be that the local health departments offer vaccines for people who can't afford the luxury of a pediatrician. I don't know if that depends on the state or the county or whatever the municipality, as to what services they offer.
And this is where it's a problem. If vaccination is not mandated and supported by the government, then you may not have this resource for people that most need it.
