Shigella-04 Vaccine Study for Shigella and Diarrhea

This study is testing a new vaccine called IVT Shigella-04 to see if it is safe and if it helps your body create protection against Shigella, a bacteria that causes diarrhea. We are looking for healthy adults between 18 and 49 years old to join. The study will compare IVT Shigella-04 to a placebo (a salt water solution that has no active medicine). Researchers will be looking at how many participants have side effects (reactogenicity events and adverse events) and for how long after receiving the vaccine. The study aims to enroll 60 participants.

Study design
This is a Phase 1, single-site, randomized, double-blind, placebo-controlled study. About 60 healthy individuals will be enrolled.
What's involved
You would receive two injections 28 days apart. Researchers will monitor you for side effects for 7 days after each dose, and for up to 6 months after the second dose.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for reactogenicity events for 7 days after each dose, and for adverse events for up to 6 months after the second dose.
