NCT ID NCT04232280
First seen May 16, 2026 · Last updated May 16, 2026
Summary
This study tested an experimental mRNA vaccine (mRNA-1647) to see if it is safe and triggers an immune response against cytomegalovirus (CMV), a common virus that can cause serious problems in newborns and people with weak immune systems. The trial included 315 healthy adults aged 18-40, some already exposed to CMV and some not. Researchers measured side effects and antibody levels after vaccination to find the best dose.
