NCT ID NCT06134804

First seen Apr 07, 2026 · Last updated May 07, 2026 · Updated 5 times

Summary

This study tested whether a new vaccine against a serious E. coli infection (ExPEC9V) can be given at the same time as the high-dose flu shot in adults 65 and older. About 959 volunteers received either both vaccines together or separately to check if the immune response stays strong. The goal is to prevent invasive E. coli disease and seasonal flu with fewer doctor visits.
