What this trial studies

This observational study aims to assess the impact of COVID-19 infection on maternal and neonatal outcomes. It focuses on pregnant women receiving prenatal care at Johns Hopkins Hospital and those admitted for delivery, particularly examining the effects of mRNA COVID-19 vaccines on their immune responses. The study will also explore adverse outcomes related to COVID-19 during pregnancy and its implications for newborns. By analyzing these factors, the research seeks to fill knowledge gaps regarding COVID-19's effects on pregnancy and lactation.

Who should consider this trial

Good fit: Ideal candidates include pregnant women receiving prenatal care at Johns Hopkins Hospital who plan to receive an mRNA COVID-19 vaccine.

Not a fit: Patients who have previously been infected with COVID-19 will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide critical insights that inform guidelines for COVID-19 vaccination in pregnant women, ultimately improving maternal and neonatal health outcomes.

How similar studies have performed: While there have been studies on COVID-19's impact on pregnancy, this specific approach focusing on mRNA vaccine responses in pregnant women is novel and has not been extensively tested.
