RotaFlash was an e-news alert that provided breaking scientific news and updates on progress made by PATH and partners toward increasing global access to vaccines against rotavirus, the leading cause of severe and fatal diarrhea in young children worldwide. PATH distributed RotaFlash from 2011 to 2016 as part of our work to help expand access to rotavirus vaccines around the world by increasing understanding of the public health burden of rotavirus disease and the effectiveness of rotavirus vaccines to prevent childhood deaths and hospitalizations.
