NCT ID NCT03251495
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial tested the oral cholera vaccine Vaxchora in 34 healthy adults to see how well it triggers protective antibodies and immune cells. Participants received a single dose, and researchers measured antibody levels, B cells, and T cell responses. The goal is to understand the vaccine's immune effects and safety.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Vaxchora (live attenuated oral cholera vaccine)
What this could lead to
If successful, this study could confirm that Vaxchora produces strong immune memory, supporting its use for cholera prevention.
What could go wrong
This is a small, early-phase study with only 34 healthy adults, so results may not apply to broader populations. The vaccine may not provide long-lasting protection.
