“Our findings may allay some patient, caregiver, and health care provider concerns. Strength of evidence is high that MMR vaccine is not associated with the onset of autism in children; this conclusion supports findings of all previous reviews on the topic. There is also high-strength evidence that MMR, DTaP, Td, Hib, and hepatitis B vaccines are not associated with childhood leukemia.

Evidence was found for an association of several serious AEs with vaccines; however, these events were extremely rare: absolute risk is low.”

“Fortunately, the adverse events identified by the authors were rare and in most cases would be expected to resolve completely after the acute event. This contrasts starkly with the natural infections that vaccines are designed to prevent, which may reduce the quality of life through permanent morbidities, such as blindness, deafness, developmental delay, epilepsy, or paralysis and may also result in death.”

— Carrie L. Byington, MD, FAAP, in a Commentary in Pediatrics, July 1, 2014.


“Our findings support that vaccines are very safe for children, and add to a substantial body of evidence that the benefits of vaccination outweigh the very low risks. Hopefully, this will engage hesitant parents in discussions with their health care providers.”
