Studies Shows No Connection Between Vaccines and Neurological Disorders, Quells Autism Fears
One in 88 children is diagnosed autistic before his eighth birthday. That rate shrinks to one in 54 for boys, who are nearly five times more likely to have the condition than girls. Swirling around this growing body of diagnoses is a debate over the disorder's cause, which scientists have not yet established, but it continues to draw speculation, particularly from people who argue rising vaccination rates are playing a key role.

However, a recent study adds to the evidence that suggests otherwise. Published in Pharmacoepidemiology and Drug Safety, the study culled publicly available data on the immunization rates of seven to 10 year olds from four managed care organizations from when they were seven months, 12 months, and 24 months old. Researchers tested the children for a variety of cognitive and physiological functions and compared the findings with the number of antigens they received during infancy. No connection was found between immunization rates and neurological disorders.
