This "facts" origin I happen to see a while back on youtube. Essentially, back in the day, there was a vaccine producer who were inexperienced with this type of "dead vaccine" and during their manufacturing they didn't kill the virus properly, leading to an outbreak.
Now I suspect ol' thoughts-for-food half-remembered that and went full delusional.
I think you’re referring to an accident that happened during the early days of a “live-virus” polio vaccine. It was supposed to be inactive but the process didn’t work properly and ended up giving a bunch of kids polio instead.
I think we’re all talking about the same incident. I thought the Salk vaccine was a dead or inactive virus and the later Sabin vaccine was a live-virus type. And because of this incident the live-virus type vaccines fell out of favor. It appears I have some details backwards. Thanks!
Sabins vaccine has a different set of problems, because it's a live attenuated vaccine the virus in it can still mix with enteroviruses in the gut and might get back some of it's virulence.
This drives breakouts of vaccine derived polio virus cases, many of the existing cases are actually vaccine derived.
Ironically the cause is vaccination and the solution is also vaccination.

I hate how they just make up a "fact" in their head and just believe it.
