“Health officials consider a vaccine to be safe if no or very few serious adverse events occur in pre-licensure clinical trials. However, the truth is that most serious adverse events which do occur in clinical trials are dismissed as “coincidental” and unassociated with the experimental new vaccine being investigated. When new vaccines are added to the universal use list, very few children have ever received the experimental vaccine in combination with other vaccines, and follow-up of these children is limited to a few days, weeks or months post vaccination. Furthermore, vaccine manufacturers and U.S. federal health agencies have not concluded studies to assess the long-term effects of a vaccination schedule with 49 doses of 14 vaccines by age six, starting at birth, and [69 doses of 16 vaccines] by age 18.
In order to fully understand the pathological effects on the developing brain and immune system of this kind of vaccination schedule, researchers would have to conduct a prospective, case controlled study comparing completely vaccinated to completely unvaccinated children living in the U.S. They would have to evaluate the children for at least 10 to 20 years for all morbidity and mortality outcomes, for pathological changes in immune and brain function at the cellular and molecular levels, and for changes in chromosomal integrity. Within the first five to seven years, differences between the two groups, in terms of biological integrity and rates of autism, learning disabilities, ADD/ADHD, asthma, juvenile diabetes and other brain and immune system disorders, would begin to emerge.”

Note: The above study has never been conducted. The main argument by the CDC against carrying out such a study is that it would be immoral, unethical not not vaccinate an entire group of children. Secondary arguments have to do with the immense financial cost of such a study and the near-impossibility of designing a study that would adequately account for all factors that might skew the results. One assumption is that participating families who would agree not to vaccinate their children might have a different lifestyle or level of education that would contribute unusually to their children being healthier, regardless.
