Flu vaccines, according to the best scientific evidence available today, will only work against 10% of the circulating viruses that cause the symptoms of seasonal epidemic influenza. Additionally, flu vaccines have been found to elicit inflammatory reactions that may harm the human heart, the developing fetus, and the fragile immune systems of our infants. So, do the theoretical benefits really outweigh the known harms?
According to the Centers for Disease Control and Prevention (CDC), "Immunity to a disease is achieved through the presence of antibodies to that disease in a person's system." This, in fact, is the main justification for vaccination, and a primary focus of vaccine research and development.
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.
