How COVID infection or vaccination during pregnancy shapes newborn immunity
Investigating the role of maternal-fetal crosstalk on neonatal immunity in COVID-19 infection or vaccination in pregnancy
This project looks at how getting COVID or a COVID vaccine while pregnant changes a mother's antibodies and a newborn's immune cells.

What this research studies
If you were pregnant and had COVID or got a COVID vaccine, researchers will use your blood, placenta samples, and your baby's cord blood to measure antibodies and immune cell activity. They will look for immune complexes and whether maternal antibodies or other signals cross the placenta and activate the baby's T cells or other immune cells. The team will compare samples from two groups followed through pregnancy to see differences between infection and vaccination and will study placental tissue to understand how maternal-fetal crosstalk happens. Findings aim to clarify which maternal responses protect newborns and which might alter infant immune development.
Who could benefit from this research
Good fit: Pregnant people who had SARS-CoV-2 infection during pregnancy or who received a COVID vaccine in pregnancy and who are willing to provide blood, placenta, and cord blood samples are ideal candidates.
Not a fit: People who are not pregnant, who never had COVID nor received a COVID vaccine during pregnancy, or those unwilling to provide samples are unlikely to directly benefit from participating.
Why it matters
Potential benefit: If successful, this work could help doctors choose better vaccination timing or strategies in pregnancy to protect newborns and limit harmful immune effects.
How similar studies have performed: Previous studies show maternal antibodies transfer to newborns and that infection can change infant immune markers, but antigen-specific fetal priming via immune complexes and detailed placental mechanisms remain relatively new.
