New vaccine aims to shield transplant patients from deadly virus

NCT ID NCT02506933

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

Summary

This phase II trial tests a vaccine designed to protect stem cell transplant recipients from cytomegalovirus (CMV), a common virus that can cause serious illness in people with weakened immune systems. The vaccine uses a modified, harmless virus to deliver three CMV proteins, training the immune system to fight off CMV. About 100 participants who have had a stem cell transplant will receive either the vaccine or a placebo, and researchers will monitor for CMV infections and other complications.

What this could mean

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

Active substance

CMV-MVA Triplex Vaccine

What this could lead to

If it works, this vaccine could help prevent dangerous CMV infections in stem cell transplant patients, reducing the need for antiviral drugs and improving recovery.

What could go wrong

This is a phase II trial with only 102 participants, so results may not apply to everyone. The vaccine may not provide enough protection, and there is a risk of side effects like graft-versus-host disease.
