Summary

This trial will study the effects of two doses of a CMV vaccine on preventing CMV disease in liver transplant recipients, using a protocol-mandated preemptive therapy strategy.

Who is the study for?
This trial is for CMV-negative people listed for their first liver transplant, who understand the study and consent to it. They must not have HIV or a history of positive CMV serology, be likely to get a transplant within 1-12 months, and if they can have children, agree to use birth control. People with recent vaccinations, certain immune conditions or treatments, breastfeeding women, those in other trials that affect this one's outcomes or who've had stem cell transplants are excluded.
What is being tested?
The trial tests the efficacy of two doses of a vaccine called CMV-MVA Triplex against placebo in preventing Cytomegalovirus infection after liver transplantation. Participants will either receive the vaccine or placebo before their transplant and will be monitored for how long they need antiviral therapy post-transplant.
What are the potential side effects?
While specific side effects aren't listed here, vaccines like CMV-MVA Triplex may cause reactions at the injection site (like pain or swelling), feverish symptoms (such as mild fever), fatigue, headaches and muscle pains which typically resolve without treatment.
