New study seeks immune clues to prevent HCMV transmission in pregnancy
NCT ID NCT07477925
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is looking for immune system markers that might predict whether a pregnant woman with a first-time HCMV infection will pass the virus to her unborn baby. Researchers will study blood samples from 90 pregnant women and their newborns to see which immune responses are linked to lower transmission risk. The goal is to develop a test that helps doctors better assess risk and guide care.
