A new study finds that one in four U.S. parents believes some vaccines cause autism in healthy children. But most parents continue to follow the advice of their children's doctors despite their own concerns about the shots.
Extensive research has not found a link between vaccines and autism, an idea that dates to a flawed British study in 1998.
The survey of U.S. parents' opinions on vaccines was released Monday in the journal Pediatrics. Lead author Dr. Gary Freed of the University of Michigan says nine out of 10 parents believe vaccination is a good way to prevent disease.
