Another influenza season is beginning, and the U.S. Center for Disease Control and Prevention (CDC) will strongly urge Americans to get a flu shot. In fact, the CDC mounts a well-orchestrated campaign each season to generate interest and demand for flu shots.
But a recent study published in the October issue of the Archives of Pediatric & Adolescent Medicine found that vaccinating young children against the flu appeared to have no impact on flu-related hospitalizations or doctor visits during two recent flu seasons. At first glance, the data did suggest that children between the ages of 6 months and 5 years derived some protection from vaccination in these years. But after adjusting for potentially relevant variables, the researchers concluded that "significant influenza vaccine effectiveness could not be demonstrated for any season, age, or setting" examined.
Additionally, a Group Health study found that flu shots do not protect elderly people against developing pneumonia -- the primary cause of death resulting as a complication of the flu. Others have questioned whether there is any mortality benefit with influenza vaccination. Vaccination coverage among the elderly increased from 15 percent in 1980 to 65 percent now, but there has been no decrease in deaths from influenza or pneumonia.
There is some evidence that flu shots cause Alzheimer’s disease, most likely as a result of combining mercury with aluminum and formaldehyde. Mercury in vaccines has also been implicated as a cause of autism.
Three other serious adverse reactions to the flu vaccine are joint inflammation and arthritis, anaphylactic shock (and other life-threatening allergic reactions), and Guillain-Barré syndrome, a paralytic autoimmune disease.
One credible hypothesis that explains the seasonal nature of flu is that influenza is a vitamin D deficiency disease. Vitamin D levels in your blood fall to their lowest point during flu seasons. Unable to be protected by the body’s own antibiotics (antimicrobial peptides) that are released by vitamin D, a person with a low vitamin D blood level is more vulnerable to contracting colds, influenza, and other respiratory infections.
