It is a heavily guarded secret within the medical establishment (especially within the corridors of the CDC) that the Cochrane Database Review, which is the gold standard within the evidence-based medical model for assessing the effectiveness of common medical interventions, does not lend unequivocal scientific support to the belief and/or propaganda that flu vaccines are safe and effective.
While the Polio Global Eradication Initiative (PGEI), founded in 1988, declares itself successful in nearly eradicating wild-type polio in nations like India, vaccine-induced polio paralysis cases far outnumber those the vaccines were intended to prevent. It is believed that vaccines produce at least 300% more cases of polio than those existing in the wild, indicating that a natural problem has been transformed into a manmade one.
Some vaccines have been shown to be more harmful, even lethal, than the diseases they are used to "prevent." Recently, attenuated yellow fever vaccine was found to be 5 times more likely to harm, and 12 times more likely to kill, than the natural yellow fever infections that only rarely occur in the wild.
