New oral vaccine aims to tackle two Diarrhea-Causing bugs at once

This early-stage study tested a new oral vaccine designed to protect against two bacteria that cause severe diarrhea: Shigella and ETEC. Fifty-three healthy adults received the vaccine to check for side effects and to see if it triggers an immune response. The goal is to develop a single vaccine that fights both infections, which are major health problems in many parts of the world.
