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.
Studies show that children with rickets, a vitamin D-deficient skeletal disorder, suffer from frequent respiratory infections, and children exposed to sunlight are less likely to get a cold. The increased number of deaths that occur in winter, largely from pneumonia and cardiovascular diseases, are most likely due to vitamin D deficiency.
Unfortunately, now, for the first time, flu vaccination is also being pushed for virtually all children -- not just those under 5.
This is a huge change. Previously, flu vaccine was recommended only for youngsters under 5, who can become dangerously ill from influenza. This year, the government is recommending that children from age 6 months to 18 years be vaccinated, expanding inoculations to 30 million more school-age children.
The government argues that while older children seldom get as sick as the younger ones, it's a bigger population that catches flu at higher rates, so the change should cut missed school, and parents' missed work when they catch the illness from their children.
Of course, this policy ignores the fact that a systematic review of 51 studies involving 260,000 children age 6 to 23 months found no evidence that the flu vaccine is any more effective than a placebo.
