Polio vaccination requires a tough trade-off, and the knowlege that either way children will suffer. The article is disingenuous when it states that "the vaccine-derived paralysis has ruined at least 47,500 real human lives in India, in children who would have likely never contracted paralyzing polio" because absent polio vaccination a lot more children would contract polio. It's fair enough to criticize the choice to go with a particular vaccine when another version has a lower risk of causing paralysis, but using this as a basis for criticizing the entire concept of polio vaccination goes too far. Read some history and you'll see just how devastating polio could be before comprehensive vaccination became routine.
