HuNoV-RRV (IMAGE) Washington University School of Medicine Caption Intestinal cells (nuclei shown in blue) are infected with a strain of rotavirus genetically modified to carry a gene from norovirus (green). Researchers at Washington University School of Medicine in St. Louis have found a creative way to make a vaccine for norovirus, the leading cause of foodborne infections, by piggybacking on rotavirus, an unrelated virus for which there are already several highly effective vaccines.
