You seem like someone who appreciates new information. You might find some new-to-you information here, https://en.wikipedia.org/wiki/Polio, here https://en.wikipedia.org/wiki/History_of_polio, or in the citations for these articles. Polio pre-dates 20th-century pesticides by thousands of years. Polio vaccines are estimated to have saved hundreds of thousands of lives.

Having a nutritious (and/or well-supplemented) diet and healthy lifestyle are important. No one doubts that. But medical records and studies have shown that that only gets you so far w/r/t to things like the Delta Variant. The only way to tell if your immune system is up to that particular task is to see how it responds to being infected. Lots of people have made the mistake of overestimating just how much their immune response is under their control. The subset whose immune systems proved unequal to the task are the ones in emergency rooms.

Given that Salk gave away the Polio vaccine for free, you have to ask what the financial incentive would be to gin up a made up virus.
