Comparing natural COVID-19 infection and vaccine-induced immunity in pregnant women and their infants

SARS-CoV-2 in Pregnancy: Comparison of Natural Infection and Hybrid Immunity in Mother-Infant Pairs

NIH-funded research University of California Los Angeles · NIH-10881968

This study is looking at how getting COVID-19 and being vaccinated during pregnancy affects both moms and their babies, especially how different types of immunity can help protect newborns.

What this research studies

This research investigates the effects of SARS-CoV-2 infection and vaccination during pregnancy on both mothers and their infants. It aims to understand how hybrid immunity, which combines natural infection and vaccination, influences immune responses in pregnant women compared to those who only experience natural infection. By studying mother-infant pairs, the research will explore the long-term immunological impacts of these different types of immunity, particularly focusing on the transfer of protective antibodies to newborns. This study leverages data from an existing cohort of mothers and infants affected by COVID-19 during pregnancy.

Who could benefit from this research

Good fit: Ideal candidates for participation include pregnant women who have experienced either natural SARS-CoV-2 infection or vaccination against COVID-19.

Not a fit: Patients who are not pregnant or those who have not been exposed to SARS-CoV-2 or vaccinated may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could enhance understanding of how to protect pregnant women and their infants from severe COVID-19 outcomes.

How similar studies have performed: Previous research has shown promising results in understanding immunity in pregnant populations, but this specific comparison of hybrid immunity is relatively novel.
