Childhood vaccination is a controversial topic with high stakes in the field of autism. The danger in declaring a positive association between autism and vaccinations that is based on unsound research methods, like those described above, is that other findings that are grounded on more solid research methods may be discarded as a result. No matter what your beliefs are in regards to vaccinations, I urge you to take caution when interpreting the results of this study.
However, the show did a fairly decent job of representing the problem. The vast majority of the scientists and pediatricians repeated the party line that “science has already proven that vaccinations do not cause autism” while a group of frustrated parents eloquently but emotionally expressed the fact that the studies have not been exhaustive and have not taken individual children into consideration.
