Despite the popular hyperbole that vaccines are "Safe and Effective", a legal battle was won that showed that no vaccine has ever been properly put through rigorous scientific safety studies. (See Kennedy and Suri ICAN vs HSS) No surprise since the testing is done by people invested in the success of the vaccine. On top of that, vaccine manufacturers are not liable for any adverse events suffered. With no accountability comes no incentive to restrict that incredibly lucrative industry. (See the National Childhood Vaccine Injury Act 1986)
