A mutation in the NPHP5 gene leads to a severe blinding disorder, Leber congenital amaurosis. Dogs with the condition that were treated with a gene therapy regrew normal, functional cone cells, labeled in red, that had previously failed to develop. The treatment led to a recovery of retinal function and vision. (Image: Courtesy of Gustavo Aguirre and William Beltran)

How news messages affect views on vaccination

News coverage of expert scientific evidence about vaccine safety is effective at increasing public acceptance of vaccines, but the positive effect is diminished when the expert message is juxtaposed with a personal narrative about real side effects.
