Join the Tdap Vaccine Pregnancy Study
Join our observational, fully virtual study to help researchers gain real-world insights about the Tdap vaccine during pregnancy. We are enrolling people who are 27+ weeks pregnant—whether you have received the Tdap vaccine or have not received it.
No study medication. No required vaccines. No clinic visits.
We simply follow your real-life decisions and collect information about pregnancy and baby’s health outcomes.
Your experience matters.
Why This Study Matters
Many vaccines and medications are recommended in pregnancy—but families and providers still want better data.
By participating, you help researchers:
- Understand how Tdap use in late pregnancy affects infant health outcomes
- Compare outcomes between those who did and did not receive Tdap
- Improve counseling and guidance for future parents
- Strengthen real-world safety data used by healthcare providers
Your participation helps shape the information families rely on.
Who Can Join?
You may qualify if you are:
- 27+ weeks pregnant
- Considering, planning, or have already received the Tdap vaccine
- Or have decided not to receive Tdap during pregnancy
We are enrolling:
- Participants who received or plan to receive Tdap during pregnancy
- Participants who have not received Tdap during pregnancy (unexposed comparison group)
You do not need to decide about vaccination to participate. We will simply follow your decision.
