A remarkable study published in the Cochrane Libary found no evidence of benefit for influenza vaccinations and also noted that the vast majority of trials were inadequate.
The authors stated that the only ones showing benefit were industry-funded. They also pointed out that the industry-funded studies were more likely to be published in the most prestigious journals...and one more thing: They found cases of severe harm caused by the vaccines, in spite of inadequate reporting of adverse effects.
The study, "Vaccines for preventing influenza in healthy adults", is damning of the entire pharmaceutical industry and its minions, the drug testing industry and the medical system that relies on them.
In the usual manner of understatement, the authors concluded:
The results of this review seem to discourage the utilisation of vaccination against influenza in healthy adults as a routine public health measure. As healthy adults have a low risk of complications due to respiratory disease, the use of the vaccine may be only advised as an individual protection measure against symptoms in specific cases.
