Different Surveys Summarized
The childhood diseases usually posed to respondents by the independent surveys involved asthma, reoccurring tonsillitis, chronic bronchitis, sinusitis, allergies, eczema, ear infections, diabetes, sleep disorders, bedwetting, dyslexia, migraines, hyperactivity, ADD, epilepsy, depression, and slower development of speech or motor skills.
In 1992, a New Zealand group called the Immunization Awareness Society (IAS) surveyed 245 families with a total of 495 children. The children were divided with 226 vaccinated and 269 unvaccinated. Eighty-one families had both vaccinated and unvaccinated children.
The differences were dramatic, with unvaccinated children showing far less incidence of common childhood ailments than vaccinated children (http://www.vaccineinjury.info/images/stories/ias1992study.pdf).
From a different survey in the South Island New Zealand city of Christchurch, among children born during or after 1977, none of the unvaccinated children had asthma events where nearly 25% of the vaccinated children were treated for asthma by age 10 (http://www.vaccineinjury.info/images/stories/ias1992study.pdf).
