Abstract
Four research articles---two research studies and two literature reviews---were compared in this review, all of which consider the legitimacy of the hypothesis that immunization vaccines are correlated with the higher prevalence of autism spectrum disorders. In short, the scientific disagreement on this issue is reasonably well established---the science repeatedly shows no solid correlation and, in turn, researchers generally do …show more content…
2).
As for the ‘Results’ section, the points of comparison between the two research studies, aside from the literature reviews, will be explained. The first point of comparison is the child’s age at first parental concern, which is found to be mostly around the time of the child’s 18th thru 24th month, “with one exception” (1999, p. 2027), in Taylor’s study. In Fombonne’s study, on the other hand, it is said, “in the Stafford sample [the main sample, selected specifically for this study], the mean age at which parents first were concerned was 19.8 months” (2001, Results section, para. 5). In
Taylor’s study, the statistic was compared to the children’s immunization records and were found to be the following: “Of the 356 cases of core or atypical autism with age at diagnosis of 18 months or greater, 233 received MMR vaccine before this age, 64 never received MMR vaccine, and 59 received MMR vaccine at 18 months or later” (1999, p.
