On the other hand, Wakefield research has lots and lots of mistakes and errors. The most remarkable one is using a small population to accomplish this study by basing it on only 12 children 11 boys and 1 girl as if you want a reliable investigation you need to have more patients who are in the same age and having equal gender. And there was no control group because of the consecutive selection of the children, he didn’t provide a baseline of data to compare it with the result and this cause increase in the chances of errors and bias (Rao and Andrade, 2011). Also according to the General Medical Council (GMC), Wakefield was the only one who wrote the last version of the research under the use of authors names and reputations, as they appear to have been having no knowledge of what he was doing (Godlee, Smith and Marcovitch, 2016). Furthermore, Wakefield focused on children who suffer from gastroenterological and other disease and neglected children who have only autism. He also based his study on children who have autism and other disorders disease and forgot about other children who don’t have autism. Moreover, he did a more unnecessary test, for example, lleocolonoscopy and biopsy sampling, lumbar puncture, electroencephalography (EEG) and magnetic resonance imaging (MRI) without their permission and approval also he tried to give the children new vaccine without telling the parent. In addition, the parents might give faulty information about the abnormal attitude of their children as they say their children were not communicated so that makes his theories based on parent remembrance. Following that he did not pay attention if there were other cases in the families of the children which might make it a genetic disease. Even though his research approved, many rules were broken. Finally, this report spread fear in parents and has lots of impact on children medical health, and it has been attracted in the media, which make Wakefield clarify the facts.
