The hazards of childhood vaccines, especially the measles vaccines, were discussed previously(1). The only recommended vaccines are Oral Polio, Oral Influenza vacinnes, and the smallpox vaccine(intradermal), intradermaly because the necessity outweighs the risk. The rest of the vaccines carry more risk than potential benefit. The present paper discusses the Influenza vaccine which significantly increases the risk of Alzheimer's Disease in normal individuals aged 65-70 (11 fold as compared to controls matched for age, sex, and geographic location), perhaps due to the mercury content, and the resultant mercury-antigen antibody complexes. The Hepatitis B vaccine is especially dangerous, perhaps becuase of the mercury content, and has produced man immune complex diseases including nephrotic syndrome and various neurologic disorders, prsumably because the complexes bind to the glial cells in the brain, and various opthalmologic diseases, presumably because the complexes bind to monocyte-derived cells in the retinal blood vessels. The risk associated with these vaccines far exceeds any potential benefit.
