Although parents are always worried about the amount of vaccine received by their child at an early age, but research shows that the vaccine, even given together in one day, did not increase the risk of autism.
In a survey in 2011, nearly a third of parents admitted they were worried that children get so many vaccines before age 2 years. In fact, not infrequently there are multiple vaccines to be administered in a single day.
In the first six months of the baby's age, he would receive about 19 doses of six different types of vaccines. At the age of 6, the average child received 25 doses of 10 vaccines.
Some previous studies have found no link between the amount of vaccine received by children and the risk of neurological disorders. Indeed, the study did not specifically mention the risk of autism.
In a recent study led Dr.Frank DeStefano of the Center for Disease Control and Prevention, the researchers took a step to see the link between exposure to an antigen (protein in the vaccine that stimulates the immune system) with the risk of children affected by autism.
The research team would prefer to see antigen exposure than the amount of vaccine received by children because it is actually the anxiety so parents are a child gets more immunological stimulation of the immune system can handle them.
According to DeStefano, the number of vaccines can not be a measure of immunologic response because the vaccine contains a variety of antigens and several antigens that provide protection for more than one disease.
He and his team analyzed information from 250 children with autism and 750 children without autism, who were born between 1994 and 1999.
Children with autism are exposed to antigens in the same amount of children without autism at age 3 months, 7 months, and 2 years. There was no difference between the two groups in the total amount of antigen received in one day.
"Anxiety parents that their children receive too many vaccines before age 2 years or been vaccinated too much during a visit to the doctor did not increase the risk of autism," the researchers write in the Journal of Pediatrics.
Actually, every day children are also exposed to many viruses and pathogens that stimulate their immune system, as well as how the vaccine. In other words, truth in a single day thousands of children receive vaccinations.
Although the number of vaccines children receive today more than children in the era of the 1990s, but the latest generation vaccine antigen less. So the child gets antigen era in the 1990s between 3,000 to 15,250 before the age of 2 years, the current generation of children received only about 315 antigens.
