ClinConnect Summary

The COVID-19 Vaccines International Pregnancy Exposure Registry (C-VIPER) is a study designed to understand how receiving a COVID-19 vaccine during pregnancy affects both mothers and their babies. Researchers want to learn about various health outcomes for mothers, such as complications during pregnancy and childbirth, as well as outcomes for their newborns, including any birth defects or health issues in the first year of life. The study will compare the experiences of pregnant women who have received a COVID-19 vaccine to those who have not been vaccinated during their pregnancy.

To be eligible for this study, women must be at least 18 years old and currently pregnant. They should either have received at least one dose of a COVID-19 vaccine during their pregnancy or within 30 days before their last menstrual period, or they should have not received any COVID-19 vaccines during that time. Participants will be asked to sign a consent form and complete a questionnaire about their health and vaccination status. This study aims to gather important information that could help improve understanding of the safety of COVID-19 vaccines for pregnant women and their babies.
