In addition to the pre-established reasons for this being a poor "study" it fails to take account of the obvious; Neuro Developmental Disorders are diagnosed. Vaccinated children are more likely to be exposed to a diagnostic environment than
non-vaccinated children, without a full health/development screening of every child in every group of the study (which didn't happen here) no conclusions can be drawn from diagnosis rates. As it is the diagnosis information in this report is anecdotal and in many cases based on each parent's own diagnosis/memory.
