First seen Jul 27, 2026 · Last updated Jul 28, 2026 · Updated 1 time

Summary

This early-stage trial is testing whether a new oral vaccine can safely protect against norovirus, the highly contagious virus that causes vomiting and diarrhea. Healthy adults aged 18 to 80 will receive a single dose of the vaccine, which targets two common norovirus strains. Researchers will monitor for side effects and measure the immune response in the blood.

Active substance
an experimental oral norovirus vaccine targeting two strains (G1.1 and G2.4)
What this could lead to
If successful, this could lead to a convenient oral vaccine that protects against the highly contagious norovirus stomach bug.
What could go wrong
This is an early phase 1 trial with only 60 participants, so safety and immune response are still unproven. The vaccine may not generate strong enough protection or could cause side effects.
