MV140 is a mucosal vaccine of inactivated whole bacteria (E. coli, K. pneumoniae, E. faecalis, P. vulgaris) with clinical efficacy against recurrent urinary tract infections (UTIs). Here, MV140 was evaluated in a murine model of acute uropathogenicE. coli(UPEC)-induced UTI using the UTI89 strain. MV140 vaccination resulted in UPEC clearance, concomitant with increased influx of myeloid cells in urine, CD4+ T cells in the bladder, and a systemic adaptive immune response to both MV140-containingE. coliand UTI89.
