Extending the Concept of Vaccinology to the Control of Multidrug-resistant Sepsis in Neonates

Standard infection control bundles have not been consistently effective in combating sepsis due to multidrug-resistant organisms (MDROs). Recent trials showing the beneficial effects of probiotics in controlling late-onset sepsis, the so-called “cross-contamination” or “cross-colonization” phenomenon that draws a parallel with the herd immunity concept in vaccinology. This editorial highlights the putative benefits of adapting the vaccinology-based concept using probiotic bacteria in our combat against MDROs.
