Another Study Finds Possible Link Between Autism & Vaccines
The Journal of Toxicology and Environmental Health has come out with yet another study suggesting possible links between autism and childhood vaccines. The study, conducted by Gayle DeLong of the City University of New York, examined occurrences of autism on a state-by-state basis, comparing the percentage of children who were diagnosed with autism by the age of eight with the vaccination rates in the state when those same children were two years old. This data was then corrected for factors including family income and ethnicity, factors that may play a role in the diagnosis of autism. More affluent parents may be more likely to seek a diagnosis, and dark skinned people, who require a greater amount of vitamin D, may be more likely to develop autism, which has been linked to vitamin D deficiency.
The results of the study indicate that there is reason to link autism with childhood vaccination. States which had high childhood vaccination rates (that is, where a greater percentage of children received all recommended vaccines by the age of two) tended to see a corresponding increase in the number of children with autism. This makes sense; there are many factors that support a link between childhood vaccination and autism. As Dr. DeLong points out, many childhood vaccines, including those for influenza that are recommended for children and expectant mothers alike, contain aluminum and mercury – toxic substances that can hamper the immune system’s ability to fight off the live viruses contained in the same vaccines. At the same time, chronic negative reactions to vaccines have been noted in both humans and animals since they were first developed, and such reactions have included fatigue, diarrhea, and seizures.
This study concludes that there is a possible relationship between childhood vaccination and autism prevalence. Although Dr. DeLong acknowledges that further research is warranted, it is encouraging to see this link being explored; up until now, there have been no studies conducted on the impact on children of the entire childhood vaccination schedule. This study is the first to take a step towards remedying the situation.
