In September 2011, German researchers carrying out a longitudinal study surveyed a total of 8000 unvaccinated children from the ages of 0 –19. As with the New Zealand study, researchers collected their data by conducting a survey using questionnaires. 
Results showed that vaccinated children were up to five times more likely to suffer from a variety of diseases and disorders than unvaccinated children.
Their results were compared to another German study (KiGGS), which examined a larger sample group consisting of 17,461 participants between the ages of 0 –17.
Dr. Andreas Bachair, a German classical homeopathic practitioner, responsible for collecting the results of the survey from the website vaccineinjury.info stated that:
“Asthma, hay fever and neurodermatitis are seen very frequently today. A recent German study with 17461 children between 0-17 years of age (KIGGS) showed that 4.7% of these children suffer from asthma, 10.7% of these children from hay fever and 13.2% from neurodermatitis. These numbers differ in western countries, i.e. the prevalence of asthma among children in the US is 6% whereas it is 14-16% in Australia (Australia’s Health 2004, AIHW).
The prevalence of asthma among unvaccinated children in our study is around 2.5%, hay fever, 3%, and neurodermatitis, 7%. According to the KIGGS study more than 40% of children between the ages of 3 and 17 years were sensitized against at least one allergen tested (20 common allergens were tested) and 22.9% had an allergic disease. Although we did not perform a blood test, around 10% stated that their children had an allergy.” 
(As this study is a longitudinal study, the number of children being studied has since risen to 13,222. To join the study, you can fill in the questionnaire provided by clicking on the link listed as the third reference at the end of this article.)
Although there were four cases of autism reported among unvaccinated children, Dr. Bachair reported that:
“Of these 4 children one tested very high for metals (mercury, aluminium, arsenic); in another case the mother was tested very high for mercury.”
However, this number pales into insignificance when we compare it to the 1 in 88 children currently being reported as autistic by the CDC. 
Other Conditions Found To Be Almost Non-Existent In Unvaccinated Children
Dr. Andreas Bachair continued her report by stating that their study found the prevalence of sinusitis, warts, skin problems and middle ear infections were also much lower in the unvaccinated children, as were the cases of diabetes and epilepsy.
She went on to say that the results demonstrated that the prevalence of many conditions in the unvaccinated children were also significantly lower.
