Mice with diverse microbial exposure histories as a model for preclinical vaccine testing

Summary In a recent issue of Cell Host and Microbe, Fiege and colleagues1 report that laboratory mice exposed to pathogens from pet-store mice exhibit impaired humoral immunity to influenza vaccination and display gene expression signatures that more authentically reflect human vaccine responses.
