I happen to one who is severely allergic to eggs. Tetanus vaccines are a danger to my life. I haven't had one in over 30 years and I'm still here at 59 years of age. I've worked around horses for many years and have yet to come across one person (or horse for that matter) that has contracted the disease, yet the spores exist in the gut of the animal. Any wounds get thoroughly cleaned with peroxide and colloidal silver. I've lied on several occasions to a doctor asking me when my last tetanus shot was. One vaccination is enough to give you a lifetime of immunity in any case. A simple titer would prove this to be true. Most vaccines are a real danger to whomever or whatever is receiving them. They contain squalene, mercury, aluminum, formaldehyde, antibiotics, detergents, and viral particles that have no place in a human body. Severe autoimmune reactions do occur, and life long illness can result. I'm not a scientist, but why they put these toxic substances in the mix is beyond me. I'm not against physicians, I'm against the premise that the only way to treat disease is to poison the patient with a toxic drug. Surgery is unavoidably necessary on occasion and I admire their skills which are often life saving.
