CDC Finds Vaccines Not Associated with Risk of Autism
An article released this week in the Journal of Pediatrics said there was no relationship between numbers of vaccines received and the development of autism spectrum disorder (ASD). The article, written by Dr. Frank DeStefano and his colleagues was the first article to deal with the “too many vaccines too soon” issue.
Scientific evidence supports that vaccines do not cause autism, even though 15 percent of parents believe that they do, according to a 2012 HealthStyles survey. More than one in five parents have concerns that children receive too many vaccines by the age of two years old and during a single doctor’s visit. However, A Centers of Disease Control and Prevention study found that most parents vaccinate their children and consider vaccines important.
In the DeStefano study, researchers collected data from managed care organizations and evaluated the number of vaccine antigens received by children during their first two years of life. Antigens are substances in vaccines that cause the body’s immune system to produce antibodies to fight disease. They compared a group of 256 children with ASD to a group of 752 without the disorder, finding that antigens from vaccines received were the same between both groups.
The United States currently has the safest, most effective vaccines in history. The number of vaccine antigens has decreased in recent years. Because of changes in vaccines, children are exposed to fewer vaccine antigens now than in the 90s, even though children now receive more vaccines.
