Did polio injections leave telltale scarring? My recent two didn’t. Smallpox vaccinations were notorious for leaving a long lasting if not permanent scar.

Yes, a wonderful vaccine, able to attain a herd immunity through a vaccination program because it stopped transmission. People lining up for it willingly because the vaccine worked against a deadly disease.
The only argument imo is informed consent, a yes or no question eg should medical treatment be forced on people? Amazing how many morons think medicines should be forced on people. Even ones that don't work and are still in testing. Even targeting children who were never at risk from the disease.

I had the injection and used to be able to see the scar, but no more. My sister had the sugar cube and I was so jealous of that. We both are happy and healthy and escaped contracting polio.

Hard to believe there are still people who believe that anyone who got the polio vaccine within the last 70 years will die of cancer, but I met one of those believers a couple of weeks ago. I'll try my luck with science over fear mongering. With science, when a mistake is discovered, it is corrected.

I remember seeing people with the vaccine scar and wondering why I didn't have one (and being glad not to be scarred like that). (Now I'm proud of my scars...)

I remember being lined up in the school, during the school day, for both the red liquid over a sugar cube and the shot....everybody was ecstatic!
if not a recipient, no more school for you....not aware of any such BS, either.
in fact your parents could not register you for any grade of school, including kindergarten, without your Shot Card even before the polio vax came out.
i also remember Public Service movies in the gym, every Thursday after lunch, where we got to see how happy Little Emily was, living in her Iron Lung, utilizing her mirror, and the last scene was the camera at the ceiling pulling back to show rows & rows & rows of Little Emilys. as the chuffing sound the iron lungs made increased.
I believe this short may still be available, in B&W of course, on Youtube.
Almost as cheerful & uplifting as "Duck & Cover"!

The oral vaccine was so successful in the US the cases that still occurred were due to rare backmutations of the vaccines into vaccine derived cases. After the switch to injectable vaccine this was no longer an issue. I had gotten the oral vaccine as a child, but after the case of vaccine derived polio in NY decided to go through the three shot series of injectable vaccine to feel more safe.
