You can also visit our Frequently Asked Questions to learn more about participating in our studies.

Who May Qualify?

You may qualify if you are:

  • Currently pregnant
  • Not planning to receive the Tdap vaccine during this pregnancy
  • Willing to participate in research remotely
  • Willing to provide permission for researchers to obtain medical records for your pregnancy and your child through 2 months of age
  • Live in the United States

What Does Participation Involve?

Participation is completed remotely and includes:

  • Up to 4 interviews (1–3 phone interviews during pregnancy, and one after delivery)
  • Questions about your pregnancy and health
  • Permission to obtain your medical records for your current pregnancy
  • Permission to obtain your child’s medical records through 2 months of age

We will not give the Tdap vaccine as part of this study. This is an observational study, which means we simply follow you through your pregnancy and collect information about your pregnancy and your baby’s health through interviews.

Why Is This Research Important?

Some people have questions and concerns about vaccines during pregnancy. Researchers need to study all pregnancy experiences—including pregnancies where vaccines are not received—to better understand potential risks, benefits, and outcomes for mothers and babies. By participating, you can help researchers gather the evidence needed to answer important questions about vaccine safety during pregnancy.

Our Ebglyss® study includes

  • 1-3 phone interviews during your pregnancy and at least 1 interview after you have your baby.
  • Your permission to obtain a copy of your and your baby’s medical records from your healthcare providers.
  • An opportunity to receive a specialized, non-invasive exam of your baby with a study doctor.
  • A neurodevelopment assessment that can also provide insight into the child’s development at approximately 12 months of age.

If you have eczema (atopic dermatitis) and have taken Ebglyss® at any point from 123 days before conception through your current pregnancy, you may qualify for this important study.

Will you take the next step and help us learn more about the use of Ebglyss® during pregnancy?

Help Us Better Understand the Possible Effects of Sotyktu® in Pregnancy

Many people need to take medication during pregnancy to appropriately manage a chronic health condition. In some cases, avoiding or stopping medication use during pregnancy may be more harmful than taking medication. Yet fewer than 10% of medications have enough information to determine their safety for use in pregnancy — this is where you come in!

MotherToBaby is currently enrolling people who are pregnant in a study examining the use of Sotyktu® (deucravacitinib) during pregnancy.

Are you currently pregnant? Did you take Sotyktu® at any point in your current pregnancy? If you answered “yes” to both of these questions, then you have the opportunity to help us learn more about Sotyktu® use in pregnancy.

We’re Collecting Info on BOOSTRIX When Taken in Pregnancy

MotherToBaby is currently enrolling pregnant people who received (or plan to receive) the BOOSTRIX Tdap vaccine in an observational study. This vaccine is recommended during the 3rd trimester of pregnancy to prevent pertussis (whooping cough) in infants under the age of 2 months. If you have already received the Tdap vaccine during the third trimester of your pregnancy or you plan to do so, we invite you to join our observational study. Participation involves providing information about your pregnancy and your baby’s development for a certain period of time after birth.

Please note that we will not ask you to receive the Tdap vaccine as part of the study; we are solely interested in gathering data from those who have already chosen to receive BOOSTRIX during the third trimester of pregnancy. If you meet this criteria, you may be eligible to participate.
