First seen Nov 01, 2025 · Last updated Jun 13, 2026 · Updated 29 times

Summary

This study tested the antiviral drug valacyclovir in 41 pregnant women whose unborn babies were infected with cytomegalovirus (CMV), a leading cause of birth defects. The goal was to see if treating the mother could lower the virus levels in the baby and reduce symptoms at birth. The approach aims to improve outcomes for infected fetuses by using a drug already known to be safe during pregnancy.
