You're a freakishly gigantic waste of bandwidth. Why are you even here?
I never claimed that Polio had been eradicated but only nearly so....
Wild poliovirus has been eradicated in all continents except Asia, and as of 2020, Afghanistan and Pakistan are the only two countries where the disease is still classified as endemic.
Recent polio cases arise from two sources, the original 'wild' poliovirus (WPV), and mutated oral vaccine strains, so-called circulating vaccine-derived poliovirus (cVDPV). There were 140 diagnosed WPV cases worldwide in 2020, a decrease from 2019's 5-year high, an 81% reduction from the 719 diagnosed cases in 2000 and a 99.96% reduction from the estimated 350,000 cases when the eradication effort began in 1988. Of the three strains of WPV, the last recorded wild case caused by type 2 (WPV2) was in 1999, and WPV2 was declared eradicated in 2015. Type 3 (WPV3) is last known to have caused polio in 2012, and was declared eradicated in 2019. All wild-virus cases since that date have been due to type 1 (WPV1). Vaccines against each of the three types have given rise to emergent strains of cVDPV, with cVDPV2 being most prominent, and such strains caused over 1000 polio cases in 2020.
In the last 12 months (5/19/20 - 5/18-21) there have been a total of 980 cases world wide.

Your chances of getting Polio are many times smaller than getting struck by lightning twice unless you live in Pakistan where there is no health infrastructure! Pretty much everywhere else in the world your chances drop basically to zero because, as I said in my previous post, it has been all but completely eradicated.
And, incidentally, the near eradication of the virus has been accomplished because of the vaccines. Many many hundreds of thousands, even millions of people, mostly children, don't have to be crippled and die young thanks to a vaccine that is significantly less effective against Polio than the Pfizer and Moderna vaccines are against COVID19.
