Possibly, but the vaccines have prevented many orders of magnitude more cases: "Since 2000, more than 10 billion doses of OPV have been administered to nearly 3 billion children worldwide. As a result, more than 13 million cases of polio have been prevented, and the disease has been reduced by more than 99%. During that time, 24 circulating vaccine-derived poliovirus (cVDPV) outbreaks occurred in 21 countries, resulting in fewer than 760 VDPV cases."[1]

- tboyd47 6y agoThere were only 350,000 cases in 1988, when the vaccine was first deployed, and 5 billion people on Earth then versus 7 billion now. How do 350,000 cases turn into 13 million, according to the WHO? [1] https://www.who.int/news-room/fact-sheets/detail/poliomyelitis https://www.who.int/news-room/fact-sheets/detail/poliomyelit...
- DiogenesKynikos 6y ago350,000 cases/year * 32 years = 11.2 million cases, which is in the right ballpark, assuming we're counting from 1988.
- gus_massa 6y ago350,000 cases/year * 32 years = 11.2 million cases They may have some more precise method, but with this estimation 11 or 13 millions doesn't seams to be too off.
