No link between autism, many vaccines, US study shows
WASHINGTON - A United States study out on Friday sought to dispel the fears of about one-third of American parents that giving a series of vaccines to children may be linked to autism.
Even though children are receiving more vaccines today than they did in the 1990s, there is no link between "too many vaccines too soon" and autism, said the study in the Journal of Pediatrics.
About one in 10 US parents refuse or delay vaccinations for their children because they believe it is safer than following the schedule put out by the Centres for Disease Control and Prevention (CDC), according to previous research.
Prior studies have already shown there is no link between vaccines and autism, including a 2004 comprehensive review by the Institute of Medicine. This time, researchers at the CDC decided to look children's exposure to antigens, the substances in vaccines that cause the body to produce antibodies to fight infection and disease.
