Didn’t know there was more than ONE POLIO VACCINE!
See my Post 15
When there were little ones in my family (20 years ago), I think there was a live virus vaccine and dead virus vaccine version.
The original polio vaccine, that was a shot, had a number of problems and was not effective, that was the Dr. Salk version I think. Dr. Sabin came out with an Oral medication vaccine that did work very well. So yes there have been different variations of the Polio Vaccine.
You’re the one calling something ridiculous while knowing nothing about it. Look up some day. The one Billy Gates pushed onto Africa killed lots. They modify / create a new vaccine, retire the previous well tested one, up the price make more $. My guess is you have at least 3 vid vax.
