New mRNA vaccine targets Epstein-Barr virus in early trial

NCT ID NCT07478952

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-stage trial is testing an mRNA vaccine called mRNA-1189 to see if it is safe and triggers an immune response against Epstein-Barr virus (EBV). EBV is a common virus that can cause mononucleosis and is linked to certain cancers. The study involves 120 healthy adults aged 18 to 30, who will receive the vaccine either under the skin or into a muscle. Researchers will monitor for side effects and measure antibody levels.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
mRNA-1189 vaccine
What this could lead to
If successful, this could lead to a vaccine that prevents Epstein-Barr virus infection, which is linked to mononucleosis and some cancers.
What could go wrong
This is an early Phase 1 trial with only 120 participants, so it's primarily checking safety and immune response. The vaccine may not work as hoped or could cause side effects.
