Where the heck are you getting that 490,000 number from? The oral polio vaccine (aka OPV/Sabin) uses a weakened form of the live virus, which known to revert occasionally to virulent form.
Here’s what the WHO site says:
“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 cVDPV outbreaks occurred in 21 countries, resulting in fewer than 760 VDPV cases.”

A total of 640,000 children developed NPAFP in the years 2000–2017, suggesting that there were an additional 491,000 paralyzed children above our expected numbers for children with NPAFP.
- danieltillett 6y agoThis is not a good paper and that number of 491,000 children is ludicrous.
