"None" will bring back polio which finally killed one of my friends when in his late 60s.
He was raised as an orphan as his entire family was wiped out by polio.
Due to polio he was a short humpback with a curved spine and screwed up lungs.
In spite of that he was able to build a successful blacksmithing business.
The last few years he was gasping for breath from taking a few steps.
That’s tough, but polio today comes from the polio jabs.
Unvaxxed children are much, much healthier than the jabbed.
