Infant Immune Response

We are inviting all infants born to mothers enrolled in the MAMA study to be considered for follow up investigations of their immune system with 3 blood tests over a year. This will provide valuable information about the impact of being exposed to biologic medication during pregnancy on the development of babies' immune systems.

How will we do this?

When you sign the initial study consent form, we will ask you to let us know if you are happy to be contacted by the MAMA Coordinating Centre about the “Infant immune response” component of the MAMA study after your baby is born. Once your baby is born, we will contact you by phone or email to see if you are still interested in taking part, and answer any questions you may have. We will make an appointment to see you and your baby at your home to sign the consent form and collect the samples. Babies will have three study visits at ages 2, 5 and 13 months. During each of the visits the babies will have blood samples taken and samples of nasal fluid collected. We will use a local anaesthetic cream to numb the skin for blood tests.

If you did not originally consent to being contacted about this element of the study and you decide that you might be interested in taking part, please contact the MAMA Co-ordinating team or the local research team at the hospital where you were enrolled on the MAMA trial. We will then update your records to say that you are willing for us to contact you about this part of the MAMA trial.
