Abstract
Laboratory mice comprise an expeditious model for preclinical vaccine testing; however, vaccine immunogenicity in these models often inadequately translates to humans. Reconstituting physiologic microbial experience to specific pathogen-free (SPF) mice induces durable immunological changes that better recapitulate human immunity. We examined whether mice with diverse microbial experience better model human responses post vaccination. We co-housed laboratory mice with pet-store mice, which have varied microbial exposures, and then assessed immune responses to influenza vaccines. Human transcriptional responses to influenza vaccination are better recapitulated in co-housed mice. Although SPF and co-housed mice were comparably susceptible to acute influenza infection, vaccine-induced humoral responses were dampened in co-housed mice, resulting in poor control upon challenge. Additionally, protective heterosubtypic T cell immunity was compromised in co-housed mice. Because SPF mice exaggerated humoral and T cell protection upon influenza vaccination, reconstituting microbial experience in laboratory mice through co-housing may better inform preclinical vaccine testing.
