Mean values of NoV VLP binding to saliva samples expressed as percentages. NoV VLPs (G1.1, GII.4-v0, GII.4-v2 and GII.4-2006b) were assayed for their ability to bind to saliva samples from 22 volunteers including non-secretors (n = 3) and secretors with blood group A (n = 8), B (n = 4) and O (n = 7). Error bars indicate standard deviations. P values indicating significant differences between NoV VLP binding are shown
