NCT ID NCT04962477
First seen Jan 07, 2026 · Last updated May 30, 2026 · Updated 26 times
Summary
This study looked at why pregnant women tend to have milder COVID-19 but more severe flu. Researchers compared nasal samples from 48 pregnant and non-pregnant women to measure how the virus enters cells and how the immune system responds. The goal was to uncover the biological reasons behind these differences, not to test a treatment.
