The review found that with rare exceptions, these vaccines are very safe.Source: Adverse Effects of Vaccines: Evidence and Causality [Institute of Medicine. 2012]external icon

    •A CDC study published in 2013 added to the research showing that vaccines do not cause ASD. The study focused on the number of antigens given during the first two years of life. Antigens are substances in vaccines that cause the body’s immune system to produce disease-fighting antibodies. The results showed that the total amount of antigen from vaccines received was the same between children with ASD and those that did not have ASD.Source: Increasing exposure to antibody-stimulating proteins and polysaccharides in vaccines is not associated with risk of autism [J Pediatr. 2013]external icon
