Hepatitis C Virus Immunity in Women and Children

Official Title

Hepatitis C Virus Immunity in Women and Children

Purpose

This is a study to find out how pregnancy affects a mother’s immune system. (The “immune system” is the part of the body that fights germs.) This study is also to find out why some babies who are exposed to infections during pregnancy get infected and others do not.

To do this project we need to study some women and babies who are infected with the hepatitis C virus and others who are not. This will allow us to compare their immune systems.

Could this study be right for you?
