Answer 1

Answer:

Did you know that once a person has been vaccinated for something, even if they get the exact same symptoms as the disease they were vaccinated against, the doctor can't diagnose them with the condition they were vaccinated against? Research the umbrella term Acute Flaccid Paralysis, and tell me what you come up with. Also, go study charts, from many credible sources, that clearly demonstrate that polio had already massively declined before any vaccine was introduced.
